"Look after Rosie......promise me......"

John shifted.

"Mary Watson... was the only life worth living."

"Mary..." John mumbled in his sleep.

"Thank you..."

"Mary—!"

He sat up.

His arms were empty. His hands were shaking, reaching for something that wasn't there, grasping at bedsheets that were just bedsheets. John sat in the dark and breathed, or tried to, his chest working against something that hadn't gotten the message that he was awake now, that it was over, that she was—

He pressed the heels of his hands against his eyes.

It was the third time this week. He knew because he had started counting, the way you count things when the alternative is not counting them.

The bed was too big. It had been too big for months and he had not moved to the other side of it, not once, because the other side still held the faint shape of someone who used to sleep there, and disturbing it felt like a decision he was not prepared to make. John lay back down slowly. He reached for her pillow without thinking, pressed it to his face, and inhaled.

Faint. Fainter than last week. The scent of her was leaving by degrees, and there was nothing he could do about that either.

He lay still in the dark.

Why did it have to be his Mary who died? Why did it have to be Sherlock who killed her? Why did it have to be the two people John Watson had trusted most completely, had built the scaffolding of his rebuilt life around, who had between them managed to take everything apart?

Sherlock Holmes.

The first person who had made a crime scene feel like an antidote to something. The first person who had looked at John Watson, broken and directionless and fresh from a war, and treated him like someone worth keeping up with. The first person who had made John think that maybe, just maybe, life after Afghanistan was not a thing to merely survive.

And the person who had stood in a room with Mary and let his arrogant mouth run ahead of his considerable brain, and got her killed for it.

Bloody fucking Sherlock Holmes.

He had mourned him once already. Two years of it. He had stood at a grave and meant every word and rebuilt himself again from nothing, and then Sherlock had walked back into a restaurant and insulted him in front of his fiancee like the two years had been an inconvenience he was mildly sorry about.

John stared at the ceiling.

Maybe Donovan was right. Maybe that was the thing about Sherlock Holmes that John had never been willing to see straight.

But today it's different; It doesn’t stay quiet.

“You promised.” Mary. Mary Watson doesn’t sound angry. That would be easier. She sounds disappointed.

Sherlock exhales slowly. Irrelevant. Memory is unreliable under chemical influence.

“You said you would keep me safe.”

A flicker now, behind his eyes. Gunshot. Blood. John shouting. The imagery, the scent of gunpowder, blood, the sound of somebody's heart giving in—

It was too loud. He pressed his fingers against his temple.

“Stop.” It came out weaker than intended. Maybe it was because of the nausea. 

Another voice cut in. Male. Familiar. “You ruined us.”

John. Of course. John Watson doesn’t shout in Sherlock’s head. He states facts, which was worse.

Sherlock’s breathing changes. Shallow... uneven.

“I solved the case,” he mutters. Pathetic defence. Even to himself.

“And you got her killed.”

"I—" His thoughts began to fragment, speeding up, overlapping. Variables. Outcomes. Missed details. The exact angle of the shot. The timing. The words he chose. Always the words—

“Your arrogance.”

“Yes.”

“Your fault.”

“Yes.”

“Your doing.”

Yes. Yes. Yes. 

The room tilted slightly. Interesting. Motor control degradation ahead of projected curve. He noted it automatically. Even now. Even like this. Always like this. Sherlock let out something that might have been a laugh. But it is devoid of any joy or relief. Still thinking, Sherlock thought. Still calculating. Still wrong.

Mary again: “Look after Rosie.”

John: “Sherlock—!”

Sherlock squeezed his eyes shut. His grip tightened around the syringe.

And before he knew it (and it was too late by the time he did) his fingers were injecting more drugs.

It didn't take long for Sherlock to realise that he was falling.

Too bright.

"—pupils fixed, resp is—"

"—get him on his side, he's—"

"—hit his head on the—"

Fragments. Arriving in the wrong order. Sherlock let them.

"Sir. Sir, I need you to stay awake."

I don't want to stay awake.

"Doc, he mixed them. Lab's running bloods now but it'll take—"

"For fuck's sake. Naloxone, now, don't wait for the—"

"Mr. Holmes. You're going to be alright."

Yeah, no shit.

The beeping pulled Sherlock back. He lay still, eyes half-lidded. Ceiling tiles. Saline drip. The particular, insulting predictability of hospitals reducing everything to pattern. His arm felt heavy with the line running into it— stabilisers, something mild, sedation that apparently believed it could negotiate with a mind like his. He turned his head. No restraints. A mistake.

The IV stand stood beside him, obedient and silent. The vial was labelled. Sedative. Safe dose. Sherlock's lips moved faintly at that. He pushed himself up, slow and deliberate, and found the line with his fingers, traced it to the regulator.

There it was. Simple mechanism: increase flow, increase dosage. He preferred to frame what came next as silence, and silence was precisely what he wanted.

His fingers adjusted the regulator. Then more. His pulse was already shifting— faster than projected, his body still compromised— and he exhaled, eyes drifting shut. This would work. Finally—

The door didn't open. It was put open, the kind of impact that came from someone who hadn't slowed down to turn a handle so much as removed the door as an obstacle.

John stood in the doorway.

He wasn't moving. Three seconds, maybe four, where John Watson stood completely still and just looked. At the IV stand. At the regulator. At Sherlock's fingers, and the particular angle of his wrist, and the deliberate, unhurried quality of what he was doing.

Sherlock watched him understand it.

He'd expected anger. Anger was manageable. Anger had structure; it escalated, peaked, burned out, and in the intervals Sherlock knew exactly how to operate. He knew how to wait it out, how to redirect it, how to say precisely the wrong thing at precisely the right moment to make it go somewhere less useful.

But John's face didn't go to anger.

It went somewhere older than that.

His chin dropped slightly. His shoulders settled. Everything about him, the set of his jaw, the stillness of his hands, the quality of his attention, reorganised into something that had nothing to do with Baker Street or Mrs. Hudson's biscuits or the comfortable, accumulated domesticity of the last several years.

Sherlock had seen photographs. He had read the file. He had, on one occasion, watched John Watson shoot a man through a window across a car park without appearing to breathe.

He had not, until this moment, fully understood what he was looking at.

"Remove your hand from the regulator."

Not a request. Not a warning. A command, delivered with the particular flatness of a voice that had been stripped of all affect except authority. The kind of voice that assumed compliance as a matter of structure, not negotiation. No preamble. No escalation. Just the instruction, and behind it, the unmistakable implication that it would be followed.

Sherlock's fingers stayed where they were.

John's eyes tracked them. He didn't move yet.

"Remove your hand," he said again, quieter this time, which was worse. Louder would have been manageable. This was a register Sherlock hadn't heard before, low and unhurried, stripped of everything decorative. "Now."

"John—"

"That was not a request." John's voice didn't rise. It levelled, which was different. A surface becoming flat and hard and perfectly, terribly even. "Hand. Off. The regulator. Look at me while you do it."

Sherlock looked at him.

He did not move his hand.

Something shifted in John's expression. Not anger. Sherlock watched him file Sherlock's non-compliance the way a person files a variable: noted, accounted for, factored into what happened next. He stepped fully into the room. The door swung shut behind him.

"Last warning," John said, still crossing the floor, still at that same measured pace, voice absolutely level. "Step back from the IV stand. Hands where I can see them. Do it now, Sherlock."

Sherlock opened his mouth.

John's hand closed around his collar.

Not a grab. A grip. The distinction was important. There was no fumbling, no excess motion, no emotional charge in it. It was the grip of someone who had decided on contact as the next step and was executing it with the same economy he'd applied to everything else. One motion: close, lock, move. And then Sherlock was moving, backwards, away from the IV stand, feet stumbling to catch up with a body that had already been relocated.

John didn't let go.

"I told you," he said, quiet and completely even, "to step back."

"I heard you—"

"Then why," John said, still in that voice, still not loud, each word placed with deliberate weight, "are we here?"

Sherlock's back met the wall. John's forearm was across his chest, not choking, not crushing, containing. A calculated application of force. Enough to communicate that Sherlock was not currently in a position to go anywhere John hadn't decided he could go.

"Get your hands up where I can see them."

Sherlock's jaw tightened. "This is excessive."

"Hands. Up."

Something in the repetition did something to Sherlock's ability to resist it. Not the words. The tone. The absolute, load-bearing certainty of it. Like it hadn't occurred to John that there was a version of this in which Sherlock didn't comply, and somehow that was more arresting than any threat could have been.

Sherlock raised his hands. Slowly. Watching John's face.

John's eyes tracked them, checked them, then came back to Sherlock's face. "Good," he said, flat. Not praise. Acknowledgement. The way a soldier acknowledges that a situation is now under control.

His forearm eased back, fractionally. Sherlock tested the distance.

"Don't," John said. Not sharp. Just immediate, and absolute.

Sherlock complied.

John held the distance. He wasn't touching him anymore, but he didn't need to. His presence in the six inches between them had the same structural quality as a hand, as a locked door, as a perimeter that had been drawn and was not being redrawn.

"Look at me," John said.

Sherlock looked at him.

"You are not going to touch that IV stand again."

It wasn't a question. It wasn't even precisely a command. It was a statement delivered with the certainty of something already decided, already true, and Sherlock found, to his faint dismay, that he had no immediate counter-argument. Not because the logic had changed. Because the voice hadn't.

"You don't—" he started.

"I'm not finished," John said. Not cutting him off. Correcting. Matter-of-fact. Like Sherlock had simply misunderstood the current order of operations. "When I am, you can talk. Right now, you're going to stand there and listen."

Sherlock's mouth closed.

John's eyes stayed on him. Not angry. Worse than angry. 

"Sit down," John said. Quieter now. Still level. "On the bed. Now."

For a long moment, Sherlock did not move.

John waited. He was very good at waiting, Sherlock was realising. It wasn't passive. It was the opposite of passive. It was a weight, patient and immovable, that simply remained until the situation resolved itself in the appropriate direction.

Sherlock sat down.

John stepped back. He moved to the IV stand without looking away from Sherlock, reached past it, and adjusted the regulator back to its correct position with the practiced efficiency of a man who had been trained to restore function under pressure. Then he pulled the chair from the corner of the room and sat down in it, positioned squarely between Sherlock and the door and squarely between Sherlock and the IV stand, and settled into it with the unhurried quality of someone who had set a perimeter and was now occupying it.

"Hands on your lap," John said.

Sherlock looked at him.

"I can see them there," John said, "or I can do this a different way. Your choice."

Sherlock placed his hands in his lap.

John looked at them. Then looked at Sherlock. Something passed across his face, very briefly, before the controlled surface came back down over it. Not anger. Something that lived behind anger, underneath it, in the place where the real weight was kept.

"Are you going to try that again," John said, "if I leave this room, Sherlock?"

Sherlock held his gaze. Said nothing.

"I asked you a question."

"I don't know," Sherlock said, which was the most honest answer he'd given in some time.

John absorbed this. His jaw worked once. "Right," he said.

He didn't move from the chair.

"Then I'm not leaving," John said, matter-of-fact. "So you may as well get comfortable."

The silence held for approximately four minutes. Sherlock counted them.

He was thinking. He was always thinking, even now, even with the sedative dulling everything, making each sensation arrive a fraction too late, the world softened at the edges. John stood between him and the IV stand. John stood between him and the door. With very little apparent effort, John had reduced Sherlock’s available options to almost nothing.

Almost.

John’s attention shifted, briefly, toward the window. A car outside. A sound. One second, perhaps two, his gaze tracking away.

Sherlock moved. He came off the bed fast. Or as fast as the sedative allowed, which was to say, not very. But he had surprise on his side, and he used it, closing the distance with the intention of slipping past John’s left, reaching the stand, reaching the—

John’s knee drove into him.

Not a grab, not a tackle. Just a single, sharp strike to his side that sent Sherlock stumbling, his balance already compromised, his own momentum turning against him. Before he had fully processed the impact, John was moving. One hand caught Sherlock’s right wrist, twisting, redirecting that failing momentum and bringing him down. The floor met him stomach-first.

The IV needle tore free from the back of his hand, leaving a thin line of red.

He hadn’t seen it coming. He, Sherlock Holmes, had not seen it coming.

“Don’t move,” John said from above and behind him. Still that voice. Still level. “Stay down.”

Sherlock’s left arm moved anyway, instinctive, scrambling for purchase against the linoleum, trying to push himself up. John caught it immediately, as if he had been waiting for exactly that, and pinned it beside the other with a force that was precise, controlled, and absolute.

John’s knee settled at the centre of his back. Not crushing. But enough to tell Sherlock that he was not getting up from the floor any soon.

“Don’t. Move.”

Sherlock tested the grip. It didn’t give. He tested it again.

John twisted Sherlock’s arm, just enough to draw a sharp intake of breath from the man beneath him. “For Christ’s sake, Sherlock Holmes.” His voice remained low, perfectly even. “If you move even an inch, I will sprain your arm.”

The linoleum was very cold on the detective's cheek. Sherlock lay still and took stock with the detached clarity of someone assessing a situation that had moved entirely outside his control. John's hand on his shoulder was not crushing— it was the opposite of crushing, weight applied with the precision of someone who knew exactly where the line was and had no intention of crossing it. His arms behind his back were held, not twisted. The difference between those two things, in John Watson's hands, was apparently quite small and entirely intentional.

"You knew," Sherlock said, to the floor.

"Yes," John said.

"You were waiting for it."

"Yes."

A pause.

"How long."

"Since you sat down," John said, "and started counting."

Sherlock closed his eyes briefly. Opened them again. "You counted too."

"I know how you think," John said. Simple. Factual. Like it wasn't the most quietly devastating thing he could have said. "And there is nothing in it I haven't seen before. In a field hospital. In a surgery. In people with a fraction of your intelligence and every one of your excuses." He let that sit. "There is nothing exceptional about what you just did, Sherlock."

Sherlock exhaled. His abdomen was making its opinions known. His arms were not going anywhere. He lay still, not because he had chosen stillness exactly, but because John had chosen it for him and had, as it turned out, chosen correctly.

"This is undignified," Sherlock said.

"Yes," John agreed. He didn't move.

"You could simply ask me not to—"

"I did," John said. "Several times. We've covered this."

Sherlock's jaw tightened. Above him, John hadn't shifted, hadn't recalculated, hadn't given any indication that this was a temporary arrangement he was reconsidering. He was simply there, weight and presence and absolute, immovable certainty, in the way that Sherlock was beginning to understand was not a mood or a decision but a thing John Watson simply was when the situation required it.

"John."

"What."

Sherlock turned his head as far as the angle allowed. "You can't hold me down indefinitely."

"I can hold you down," John said, "for exactly as long as necessary."

"And when does that end."

John looked at him. His expression had that quality again, stripped back, load-bearing, the grief and the fury wound so completely through each other they'd become structural.

"When I believe you," John said quietly, "that you're not going to do something I can't undo."

The room was very still after that.

Sherlock looked at the floor. His arms were behind his back. The thin line of red on the back of his hand had stopped. Somewhere down the corridor, wheels on linoleum, indifferent and ongoing.

He didn't say anything. Neither did John. John looked down at him.

"You think," he said, still in that voice, still stripped of everything decorative, "after everything you've done, you get to follow her?"

Sherlock coughed. His lungs were still negotiating. "Not follow," he managed. "I was simply—"

"No." John Watson cut him off. "You don't get to explain this away. I know what you were doing. I know exactly what you were doing, and you are going to lie there and listen to me."

Sherlock went still.

John's weight was a constant, even pressure across both shoulders. Not punishment. Containment.

"You don't get an easy way out of this."

John's voice changed then, barely, a single thread of it pulling taut beneath the surface of the control. The control itself didn't break. It held. But Sherlock could hear what it was holding against now, could hear the weight of it.

"You don't get to leave me here with this."

The crack was so small. A hairline fracture in something that had been holding an enormous amount of weight for a very long time.

Sherlock strained his neck, trying to assess the older man.

John's jaw was set. His eyes were steady in the way eyes are steady when the person behind them is working very hard to keep them that way. He was breathing through his nose, measured, the kind of breathing you learn when you need your hands to stay usable.

He was furious, Sherlock realised. Not the loud, combustible kind. The deep, cold, load-bearing kind. The kind that had kept John Watson functional through things that should have broken him and probably had, quietly, in ways he never showed anyone.

John looked back down at him.

"You don't get to do this," he said, quieter now. Still flat. Still that voice. "Not on my watch."

"You forgot," Sherlock said, "that you managed before."

John's expression snapped.

"I managed because I thought you were dead!" The control broke, just for a moment. "Barely! I managed barely, Sherlock, and that was—" He stopped. Started again. "There's a difference. Between thinking someone is gone and watching them choose it."

The room felt very still after that.

Sherlock stared at him. Something was happening that he didn't have clean language for. Something that was interfering with his ability to construct a proper response, which was inconvenient because a proper response was currently his only viable strategy.

"You promised her," John said. His voice had dropped again, gone hoarse. "You promised Mary."

There it was.

The name.

Sherlock's chest hitched. Not quite a breath. Not quite anything. He had been, up to this moment, functioning at some level of remove, processing the situation through whatever thin layer the sedative had managed to install. Clinical. Observational. Safe.

Mary.

He couldn't find the remove anymore.

"I failed," he said.

John's jaw tightened. "Yes."

The word landed without cushioning. Sherlock had expected an argument. A reframing. Something that might allow him to rebuild the logic that had gotten him this far. Instead John just— agreed. And somehow that was the thing that made the floor feel more solid beneath him, more real, more unpleasantly present.

"Then I should be removed."

"No," John said. Immediately. Like he'd been waiting for it. "You don't get to reduce it to that. Like it's just another experiment that went wrong. Like you can weigh it up and come out the other side with a clean conclusion."

Sherlock's gaze drifted, unfocused. "It is—"

"Look at me."

He didn't want to.

Which, unfortunately, meant he did.

John's eyes were wrecked. Not performing it, not weaponising it, just wrecked. Red at the edges. Exhausted in a way that had nothing to do with lost sleep. Alive in a way that Sherlock found, suddenly and without adequate warning, very difficult to look at directly.

He looked anyway.

"She would not want this," John said. "You know she wouldn't. You knew her. So don't. Don't use her as a reason. Don't do that to her."

Sherlock's throat tightened. He said nothing. For once he had nothing to say that wouldn't make it worse, and the absence of language felt like standing on the edge of something structural.

"If you leave as well—" John started.

He stopped.

Something moved across his face. He looked away for a moment, jaw working, and Sherlock watched him swallow whatever the first version of that sentence was going to be. Watched him find a version he could actually say out loud.

"If you leave as well," John began again, quieter, "what will become of me?"

The sedative was pulling at Sherlock's edges. He could feel it, the slow softening of things that were usually sharp. Timings. Angles. Calculations. All of it going slightly imprecise. But that sentence— that sentence landed with complete, terrible clarity.

He didn't answer.

He wasn't sure he could.

John's grip on him hadn't loosened. "I need Sherlock Holmes," he said. "Not the idea of him. Not the memory of him. Just you. It has to be you."

Sherlock's lips parted. No reply came. The words existed somewhere, presumably, but the route between thought and language appeared to have been compromised. He was aware that his breathing had changed. That his eyes were doing something he would have found unacceptable twenty minutes ago. He was aware that John was still holding him down on a hospital floor and that he was not, in any meaningful way, trying to get up anymore.

"I don't—" he started.

Stopped.

"I don't know how to—"

The end of that sentence existed too. He simply couldn't say it.

He didn't need to.

John looked at him for a long moment. The machines beeped. Somewhere down the corridor someone was moving, the sound of wheels on linoleum, entirely indifferent to the two of them on the floor.

"Then don't," John said finally.

Sherlock's brow furrowed, barely.

"Just don't die," John said. "We'll deal with the rest later."

"That's not a plan."

"No," John agreed. "It's not."

The sedative pulled harder. Sherlock's thoughts were losing their edges, slipping out of formation, and he found he lacked the will to call them back.

"…John."

John leaned in immediately. "What?"

Sherlock swallowed. The word snagged somewhere unfamiliar on the way up, like it had to pass through something that didn't usually open.

"…Stay," he said.

John didn't answer straight away.

He knew why. That was the thing— he had enough clarity left for that much.

"I'm not going anywhere," John said.

Sherlock's grip on consciousness loosened after that. Not falling. Not the way it had been before, the deliberate downward pull of it, the chosen dark. Just— slipping. Edges dissolving. The ceiling tiles blurring into something abstract and unimportant.

John's hand was still on his shoulder.

Sherlock noted it. Filed it somewhere that wasn't quite thought.

And for once, the silence that followed wasn't empty.

When Sherlock blinked back into being conscious, he found himself on the hospital bed again. Sherlock stayed still longer than necessary. Not out of weakness. He told himself that, anyway. It was… observation. Yes. Taking stock. His body felt like it had been poorly reassembled; his shoulders ached faintly, and his head was thick with the lingering drag of sedation. Unpleasant. Inefficient. But more or less alive.

How irritating.

His gaze slid sideways, and though the great detective would never accept it, he was happy and relieved to see that John was still there. Slumped in the chair, chin dipped toward his chest, one arm hanging awkwardly off the side. It looked deeply uncomfortable. Sherlock watched him for a moment. Then, because he was apparently determined to make poor decisions in rapid succession lately, he spoke. “…John.”

John jerked awake instantly. Not gradual, not confused, but just straight to alert. Soldier. Always.

“What?” His eyes locked onto Sherlock, scanning fast. “You with me?”

Sherlock blinked once. “Regrettably.”

John exhaled, tension bleeding out in a sharp, controlled breath. “Right. Good. That’s-that's good.”

A pause.

“You look terrible,” Sherlock added.

John let out a short, incredulous laugh. “Cheers. You look like death warmed up, so I think I’m still winning.”

“Temporary condition.”

“Let’s aim to keep it that way.”

Silence settled, but it wasn’t the same suffocating kind from before.

John stood, stretching slightly, then stepped closer to the bed. “Can you sit up?”

Sherlock tried to sit up, straining, but failed. It seemed as if John did a very good job in landing his knee squarely to the weak spot.

John caught him before gravity could make a point about it, one hand steady on his shoulder, the other bracing his arm. Efficient. Careful. Familiar in a way that made something unpleasant twist low in Sherlock’s chest.

“I don’t require assistance,” Sherlock muttered.

“Yeah, clearly,” John shot back, adjusting his grip. “That’s why you nearly keeled over just now.”

Sherlock allowed himself to be pulled upright. Temporarily. Definitely not because his vision was still doing that inconvenient blurring thing.

John watched him for a second, assessing. “We’re getting you discharged.”

Sherlock frowned faintly. “That seems… premature.”

John raised a brow. “You want to stay?”

A beat.

“…No.”

“Thought so.”

The hospital discharge process was, in Sherlock’s opinion, offensively slow. Forms, signatures, warnings about “proper recovery” and “substance misuse.” He ignored most of it. John didn’t. Of course he didn’t.

By the time they stepped outside, the air felt sharper. Colder. Real. Sherlock paused, just slightly. John noticed.

“You going to faint again, or are we good?” he asked.

Sherlock straightened. “I don’t faint.”

“Mm.”

A cab was flagged down with minimal effort. They climbed in, John giving the driver the address without hesitation. “221B Baker Street,” he said.

The car pulled away.

For a while, neither of them spoke. But eventually, because silence apparently wasn’t unbearable anymore, Sherlock broke it.

“…How did you know?”

John didn’t look at him. He kept his gaze fixed out the window.

“Mrs. Hudson,” he said. “She found you. Called the ambulance.”

Sherlock’s expression shifted, faintly. “I see.”

“And then,” John continued, voice tightening just a fraction, “your brother decided to get involved.”

Of course he did.

“Mycroft called me,” John added. “Didn’t bother explaining much. Just said it was urgent.”

Sherlock let out a quiet breath. “Vague as ever.”

“Understatement of the year.”

Another pause.

John finally glanced at him. “You didn’t think anyone would notice?”

Sherlock’s lips pressed together briefly. “Irrelevant variable.”

“That’s not an answer.”

“It’s the only one you’re getting.”

John studied him for a second longer, then looked away again. “Right.”

The cab slowed as it turned onto Baker Street.

Something shifted in Sherlock’s posture. Subtle. Barely there. But it was enough.

“Our flat,” John said, quieter now. Not quite a question, nor reassurance. His gaze fixed on the familiar building as it came into view. Windows. Door. Everything exactly where it should be.

Unchanged. Despite everything.

“…Yes,” Sherlock replied.

The cab stopped. John paid the driver, then stepped out, moving around to Sherlock’s side before he could attempt something idiotic like proving he could stand unassisted.

Too late.

Sherlock was already halfway out. He swayed. John caught him.

“Brilliant,” John muttered. “Really selling the independence.”

Sherlock exhaled slowly, allowing the contact this time. “Temporary,” he repeated.

“Keep telling yourself that.”

They stood there for a moment, in front of the door. On the threshold of something neither of them was particularly equipped to define. Then John shifted his grip slightly.

“Come on,” he said. “Let’s get you upstairs.”

Sherlock hesitated for a second. Then, quietly, almost imperceptibly, he leaned into the support.

And this time, he didn’t pretend it was anything else.

"God, Sherlock…" John muttered under his breath as he entered the living room.

He didn't go to the couch first.

He crossed to the kitchen. Opened the cabinet Sherlock thought he didn't know about. He did. He'd known for some time. He removed everything in it without comment, dropped it into the bin bag he'd found under the sink, and dragged the bin itself all the way in front of the door.

"John—"

"Don't."

"Those are not all—"

"Sit down."

"I am sitting down."

"Then keep sitting down and don't. Talk." John crouched beside the armchair, retrieved something from underneath it, stood again.

"That's a controlled substance," Sherlock said. "Technically speaking, you're—"

"Sherlock." John didn't look up. "What did I just say?"

Sherlock closed his mouth.

John pulled open a drawer. Checked it. Moved on. He was thorough in the way trained people are thorough— no wasted motion, no second-guessing, no pausing to negotiate with the situation. He simply proceeded through the flat with the quiet, load-bearing authority of someone who had decided what was going to happen and was now making it happen.

Sherlock shifted on the couch. "You're being excessive."

"Mm."

"The majority of those were for—"

"A case? I don't care."

"This is my flat," Sherlock said.

John looked at him. "Yes," he said. "It is." Then he went back to work, which was somehow worse than any argument.

Sherlock watched him move through the room and found he had no strategy for this. John was simply removing the problem with the same quiet efficiency with which he had once cleared a room, and there was nothing for Sherlock's considerable intellect to get purchase on.

"You can't—"

John stopped. Turned. "Can't what?"

A pause. Sherlock's usual precision failed him.

"Say it," John said. "Finish the sentence. Tell me what it is I can't do."

Sherlock said nothing.

John looked at him for exactly one second. Then: "Where's the rest of it?"

"I don't know what you're—"

"Where. Is. The rest of it."

"I don't remember—"

John looked at him.

Just looked. The kind of look that had nothing behind it except certainty, and the complete, load-bearing patience of a man who had all night.

"…Bedroom," Sherlock said, after a moment. "Second drawer."

John disappeared. Sherlock heard the drawer open. A pause— longer than it should have been, which meant the amount was worse than John had expected. Then the sound of things being removed, unhurried, thorough. When John came back, he was carrying enough that something in Sherlock's chest tightened involuntarily, though he would have strongly denied it.

The army doctor set everything down, and then he turned and looked at Sherlock properly for the first time since he'd started— and something in his face had shifted. Gone colder. More deliberate. The quality of attention that meant he had finished with one phase of things and was beginning another.

"William Sherlock Scott Holmes."

Sherlock went very still at his full name.

John crossed the room and crouched in front of him, eye level, unhurried, and his eyes when they met Sherlock's were not furious exactly. Fury was too simple for what was there. It was something that had burned through furious and come out the other side as something colder and far more permanent.

"Listen to me very carefully," John said, quiet and absolutely even. "Because I'm only going to say this once, and I need you to understand that I mean every single word of it."

Sherlock said nothing.

"If you use again," John said, "and I find out— and I will find out, because I know every hiding place in this flat now and I will be back to check— I will break your arm." He held Sherlock's gaze without blinking. "Not as a figure of speech. Not as a threat I don't intend to follow through on. I will break your arm, and then I will sit with you while it heals, and for six weeks you will not be able to inject anything into it, and we will call that a start." A pause. "Are we understanding each other?"

The flat was very quiet.

"You wouldn't," Sherlock said. Not a challenge. Something much closer to a question.

John looked at him for a long moment.

"I have pulled three people out of burning vehicles," he said. "I have performed surgery in a ditch with no anaesthetic and a penknife. I have done things in the service of keeping someone alive that I will not describe in this room, in this context, to you." His voice didn't waver. Not a millimetre. "Do not sit there and tell me what I wouldn't do."

Something happened behind Sherlock's eyes. Something that didn't have a name yet.

"…Understood," he said quietly.

John held the eye contact for one more beat— making sure Sherlock knew he was being taken seriously and that was not a comfortable thing— then stood.

"Good." He moved to the window ledge.

"I keep nothing there," Sherlock said.

"Mm." John checked anyway. "I'll decide that."

He tied off the bin bag. Set it by the door. Dusted his hands together once, like a full stop, and then stood in the middle of the room and looked at it properly. When he was satisfied, he sat down across from Sherlock. And only then, only once the room was done, did something in his posture settle. Very slightly, almost imperceptibly, the way a soldier stands down when the situation is contained rather than resolved, but settled nonetheless.

"Right," John said.

A silence.

"You're going to see someone," he said. "A professional. Starting this week."

Sherlock's eyes narrowed. "I don't see how that would—"

"I wasn't asking," John said. "I'm telling you. You will make an appointment, you will attend it, and you will continue attending it. That is what is going to happen."

"Therapy is not designed for a mind like—"

"Sherlock." John turned. His voice had that quality again, flat and load-bearing, the one that didn't invite negotiation. "You are going to sit down with someone who is qualified to help you, and you are going to do it because I am telling you to. That is the entire conversation."

Sherlock's mouth pressed together. "I can manage myself—"

John crossed his arms. "You almost killed yourself twice today."

The younger man opened his mouth trying to retort, then closed it, looking down. He knew John was right. He was always right when it came to his health.

"Once in Baker Street," he continued, "and once in a hospital bed with a sedative drip. That is your management, Sherlock. That is what managing looks like for you." He held Sherlock's gaze. "So you will talk to someone. And if I find out you've cancelled an appointment, or failed to make one, or decided unilaterally that you've had enough sessions, I will take you there myself and sit outside the door until it's done." A pause. "Are we clear?"

Sherlock looked away.

"Are we clear," John repeated. Not louder. Just again.

"...Yes," Sherlock said, very quietly.

"Good." John held his gaze for another moment. Then he uncrossed his arms. "Next. I'm moving back in."

A pause.

"...For surveillance purposes?" Sherlock asked.

"Call it whatever you like."

"That's—" Sherlock started. Something shifted in his expression. The familiar machinery of deflection beginning to turn. "You don't have to. I'm not— you shouldn't feel obligated to—"

"Stop."

"—waste your time on someone who—"

"Sherlock—"

"—who doesn't deserve—"

The chair scraped back hard.

John was on his feet before Sherlock finished the sentence, and the sound that came out of him was not the captain-voice, was not the flat controlled register he'd used in the hospital, was not anything load-bearing or measured or contained. It was raw and it was loud and it filled the flat in a way that left no room for anything else.

"Don't." He crossed the distance between them in two steps and his hand came down on the arm of the couch, not at Sherlock, never at Sherlock, but hard enough that the whole frame shook. "Don't you dare finish that sentence."

Sherlock went very still.

John's face was close. His jaw was tight, his eyes were furious and wrecked and wide open in a way he never allowed, and his voice when it came again was shaking, actually shaking

"I have been holding this together all day," he said. "All day, Sherlock. Since Mycroft called me. Since I walked into that hospital room and saw what you were doing." His voice cracked down the middle. He didn't stop. "I have watched you nearly die twice today!" The words came out ragged, not measured, not clipped, just torn. "Twice, Sherlock! And you are sitting there telling me you're not worth my time? You are going to sit there and say that to my face?"

Sherlock said nothing. His hands had gone very still in his lap.

"Say it again," John said, voice cracking at the edges. "Go on. Say it again and see what happens."

He stopped. Turned away. His hand went to his mouth.

For a moment he just stood there, back to Sherlock, shoulders rigid, breathing hard through his nose. He pressed his mouth shut, breathed in hard through his nose, and Sherlock watched him wrestle with it, watched the moment John Watson stopped containing something and let himself feel the full weight of it instead.
