Chapter Text
The storm came in like a slow breath turning into a scream.
It spilled from the ridgeline in aching pulses—thunder groaning like some ancient beast in mourning, lightning splitting the sky in jagged veins of fire. The rain didn’t fall so much as beat the ground senseless, soaking the roots of trees and flattening everything in its path. The forest below bent and howled, and Castiel stood in the doorway of his cabin like a man carved out of stone, sleeves soaked, hair sticking to his neck, one shoulder wedged against the frame as if the wind might knock him down too.
He didn’t move.
Not until the scent hit him.
Omega.
Hot and raw and wrong. Twisted with panic and blood and scent suppression patches half-melted by fever. It lanced through him like lightning—not down his spine but straight through his chest. It was the kind of smell that made most Alphas surge forward.
But Castiel’s body locked.
Just like it always did.
That’s what Alpha Instinct Reversal did. It caged you. Wrapped instinct in barbed wire and made it something unusable unless someone else—someone softer—opened the door.
And still—
Still.
Even frozen in place, he felt it. The scream inside his bones. The scream that said: someone needs you.
A thud broke the trance. Just outside. Something heavy.
Then—ragged breathing.
He turned on instinct, even though instinct had betrayed him more times than he could count.
The porch door flung inward with the wind.
And there he was.
The Omega.
Collapsed halfway inside the doorway like the storm had tried to swallow him and failed. His fingers—torn, dirty—scraped against the floorboards like he was still crawling even now. Blood smeared down one arm, soaking into denim. His jacket had been shredded by the forest, by the wind, by something worse. He was narrow-framed, too lean, too pale. And the heat coming off him wasn’t right. It was the kind that burned through the bones first.
Castiel couldn’t move.
His knees locked. His shoulders stiffened.
Every inch of him screamed protect, help, move, and still he stood like a coward, trembling with the weight of his own biology.
The Omega looked up, just barely. Eyes glazed. Lips cracked. His whole body shaking with the effort of simply existing.
“Help,” he rasped.
One word.
Just one.
And something in Cas shattered.
The paralysis broke like glass hit with a hammer, and he was on the floor beside him before the word had fully passed between them.
“May I?” he asked, voice hoarse, heart hammering.
The Omega nodded. Not even a nod, just a twitch of the chin. But it was permission.
And Castiel moved.
He pulled the Omega into his arms gently, one hand cradling his skull, the other already checking for warmth, for pulse, for breath. The scent of blood and heat nearly knocked him over.
“You’re burning up,” Cas whispered, guiding them inside, kicking the door shut with a foot, rain pounding behind them like a war drum. “You’re in heat, but it’s starved. It’s wrong. You’re not supposed to feel this alone.”
The Omega didn’t answer. He sagged against Cas’s chest, shivering, unconscious. Gone.
Cas worked quickly, his mind calculating and soft at once. The couch became a place of triage. He laid the Omega down, whispering each step:
“May I take off your jacket?”
“May I clean the blood?”
“May I lift your shirt?”
Nods—weak, barely-there—guided every move.
He cleaned what wounds he could. Bruises marbled his ribs. Shallow cuts lined his hands. And there, on the inside of his forearm—half-peeled suppression patch, barely clinging to skin.
Cas peeled it off gently, hating the way the Omega flinched even in sleep.
“I’ve got you, sweetheart,” he whispered, thumb stroking the curve of his wrist.
The Omega wasn’t breathing right.
Cas felt it. The shallow rise, the too-long pause. He pressed two fingers to the side of his neck.
Weak.
No, no, no.
He tilted the Omega’s head carefully, opened the airway, mouth to mouth.
One breath. Two.
“Stay with me,” Cas murmured, giving compressions, eyes burning. “You asked for help. Don’t take that back.”
And then—
A sputter.
The Omega’s back arched off the couch as he gasped, choked, coughed.
Air rattled in. Not enough.
Cas caught him again, held him up, pressing their foreheads together.
“Breathe with me,” he begged. “Come back. Please.”
The Omega drew another ragged breath, this one deeper.
Then another.
His body sagged, finally, and Cas caught him fully this time. Not as a psychiatrist. Not as an Alpha trying to survive his own damage.
But as something else.
As someone who didn’t want to lose this stranger.
Cas whispered to him, even as he passed out again.
“You’re not alone. Not anymore. I swear it.”
He stayed kneeling beside him until the fire burned down to embers.
