Summary
Emily Prentiss never expected to question her heart so late in life. She always thought she was straight, and that her bond with JJ was nothing more than friendship. But after their fallout and Will’s death, she realizes there’s a depth between them she can’t ignore. JJ loved Will, she chose him, and Emily respects that. His absence doesn’t change the past, but it forces Emily to face truths she has long avoided.
As Emily untangles her feelings for JJ, she crosses paths with Dr. Maja Keller; first a fleeting encounter, then an unexpected friendship, and finally something undeniable. For the first time, Emily learns what it means to be seen, pursued, and cherished with the same loyalty she has always given others. Amid grief, longing, and the weight of old choices, she discovers a love she never thought possible, and one she can no longer deny.

Summary
Michael is okay. Kids are resilient and even with Henry off to college, he’s got no shortage of male role models to choose from. Luke is his favourite, which JJ is pretty sure is only because Luke is Aunty Penelope’s favourite and Michael worships the ground she walks on. So, Michael has Luke and Penelope, Henry has Spence, and JJ has all of them and none of them. Most days it feels like she’s on her own.
“That’s not totally true though,” Dr. Ochoa says. “You have Emily.”

Summary
By December, Ava knows where the mugs go, which stair creaks, how Henry pretends not to care and Michael never stops talking. What Ava doesn’t know is how to feel normal in a life that wasn’t supposed to be hers.
JJ knows exactly how long it takes for Ava to answer when she’s having a bad day, how to make pasta that everyone will actually eat, and how to pretend she isn’t terrified of messing this up. What JJ doesn’t know is how to be a mother to a girl who flinches at sudden noises and doesn’t always believe she deserves to stay.Over the course of one December, Ava starts to test the fragile idea that she is more than “the broken girl” from a headline. She’s a daughter in a house that isn’t legally hers, a sister in a family still learning how to fit around her scars, a teenager who might get to choose what comes next. And JJ, standing beside her in grocery store aisles, at therapy doors, and under New Year’s fireworks, has to believe that loving someone might actually be enough.
Glass Lights continues Ava and JJ’s story from Paper Shadows, not with miracles or neat endings, but with two people learning how to hold each other’s fear and still move forward, one winter day at a time.

Summary
Emily Prentiss got kicked out of her London school for kissing a girl. Now she's stuck in suburban Virginia, wearing too much eyeliner and smoking behind the gym.
Jennifer "JJ" Jareau is Rosewood High royalty. She's mean when it's funny, shallow when it's easy, and has never questioned her perfect life because why would she?
They're supposed to hate each other. They do hate each other.
The problem is, hate takes energy. Hate means paying attention. And somewhere between library arguments and parking lot confrontations, between literary analysis and late-night texts, hate starts looking suspiciously like something else.
(featuring: JJ's terrible boyfriend, Emily's worse attitude, competitive bitchiness, emotional walls made of steel, both of them being disasters, and the world's longest "oh fuck" moment).

Summary
"Agent Jareau,” the unsub says, playing with the sound of it on his tongue. He’s now back in front of her, with an adjustment of the gun in his hand, he nods it in her direction, “Truth or dare?”
“JJ,” Emily’s voice is barely there. It allows JJ to ignore the worry there. Her eyes remain on Casey, even as she sees Emily finally shift enough to grab a piece of the broken mirror.
There’s hope.
She lifts her chin, “Truth.”
Or JJ and Emily find themselves in another hostage situation, except this time they're together.
*A complete 14x05 rewrite*

Summary
"There’s a familiar desperation in JJ's gaze that Emily wants nothing more than to alleviate, a harrowing pain she’d readily give her own life to strip away, but can’t. This time, there are no rabid dogs to shoot, no unsubs to toss off buildings, no quick thinking capable of saving the day. Will is simply gone, and the world will continue without him.
There is no other choice."
Missing moments between Emily and JJ from season 18. One moment per episode, starting from 18x02.
