Summary
Jay knows that, so he lets out a breath, trying to focus on the facts they have: Antonio didn’t say who was being held hostage, just that it’s in a pool area. Which is actually more terrifying than anything else, given Hailey’s history of throwing herself into bodies of water to solve cases. He knows he has to trust her, has to trust that the team wouldn’t let her do anything dumb, but he doesn’t know what’s going on yet. He’s allowed to panic.
The drive simultaneously takes forever and is over in a minute, it seems. It takes everything in him to not lose his shit and maintain some semblance of professionalism when he sees the look on Antonio’s face. He’s got to be a leader, to act like this is just any other day, not one where his wife is possibly the hostage.
“It’s Upton,” Antonio says, and Jay feels his heart stop.(or: Jay's SWAT sergeant. Hailey gets held hostage again. he has a totally normal response to that.)

Summary
An old friend. A new invitation. And a life Jay couldn’t even imagine—until he sees what’s really going on behind the glass towers of Chicago’s elite.
Detective Jay Halstead hasn’t heard from Maurice Campbell in years—not since they took two different paths out of the same South Side streets. But when Maurice resurfaces, successful, charming, and living high above the city in a penthouse built on secrets, it seems as if nothing had changed between them.
Jay becomes part of partys, drinks and poker and gets a glimpse into a life that looked nothing like the streets they came from. But beneath the surface, something’s off. The kind of off that sits too quiet. That watches too closely. That hides behind designer suits and perfect smiles.
The bruises no one talks about. The tension no one dares to name. The laughter that sounds a little too loud, a little too wrong. The carefully measured calm in his voice. The shadows that pass too quickly across her face—until they don’t.
It's not a love story.
It’s a story about silence.
And what happens when it finally breaks. -

Sparks fly, tension builds, and old wounds resurface as their past collides with the present inside the heat of the fire academy. But what starts as a professional reunion quickly spirals into something deeper, messier and far more dangerous.
Love, loyalty, and survival all hang in the balance when the lines between personal and professional get blurred beyond repair. Welcome to a whirlwind story where nothing stays buried for long... -

Summary
Will opens one of the envelopes, then drops the letter to the table and buries his face in his hands.
“What’s wrong?” Jay asks, setting down his coffee.
“I am so screwed.” Will’s voice is muffled by his hands. “My malpractice insurance got canceled.”A little slice-of-life fic set in my Foster Kids AU, which could probably alternatively be titled "The Halstead Brothers and the Terrible, No Good, Very Bad Day".
