Loner. Violent Video games. Loser. That was Jay in high school. But now he's rich, successful and when he sees the resume of Erin Lindsay, one of his tormentors in school and the girl who had broken his heart, applying to be his personal assistant, Jay also has the perfect plan for revenge. Linstead AU

Looking to her is always a quick reflex. When he looks to her he gets the validation that they're in this together, that they'll always be good. Until she's no longer there. (A follow-up of "Follow You" from Jay's POV)

It was supposed to be just a simple movie night between partners... wasn't it? This is what happens when Upstead lets their tension boil over!

Just an alternative version of the Upstead scenes in each episode. The words we wished they would speak!

STOP...it was all well and good until the messages actually did stop. Suddenly it becomes a race to save one of their own.

Erin and Jay are expecting their first baby together but when an unexpected person suddenly becomes a part of their life, will they be able to make it work?

Don't own anything but my O/C. Rated M. Darla needs to stand on her own, but with Hank Voight, you don't know. May have Chicago Med or Chicago Fire appearances.

This is a Linstead high school fanfiction. Jay and Erin were partners in Police Explorers. A program where high school students work with select officers and learn the ins and outs of police work. Jay and Voight were on a ride along, and get one call that changes everything.

Erin grew up a street racer but after their hard break up six years ago, she left that life - left him behind. She didn't realize how much she missed racing and him until a case brings her back home. Linstead AU.

"I just ... I know this has to end, no matter how much I don't want it to. I just want to forget for one night, that nothing's changed. That it's just you and me. I just want to end where we began." LINSTEAD, post 4x23 (M for sexual content)

Slapping the snooze button, I cast a bleary eye towards the early morning light filtering through my blinds. For a moment, I wondered why I was awake when my body was telling me to ignore the fact it was a few minutes before six in the morning and to go back to sleep. Takes place after episode 5x18 "Ghosts"

Jake from Chicago and Ella from New York meet in the summer camp. They look confusingly similar and finally realize that they are twins.

The team spend the week in Wisconsin at Jay's families cabin for a team building week. It's set in the future. Basically - Erin didn't leave, Antonio hasnt left and is in IU and Al is alive. Just ignore everything after Jay finding out about Abby in S4 ;) - I know I do! A lot of linstead but a lot of team talks, too.

An Upstead fic. IN PROGRESS. It's been a rough week for the Intelligence Unit at District 21. Now it's Friday (the 13th) and a full moon to boot. Should Detectives Jay Halstead and Hailey Upton be worried?

Hailey confesses to Jay the night before being sent to NY to work with the FBI. And while all she desires is happiness with her partner, the love of her life, someone from her past threatens to blow it all to pieces.

Jay comes home from the war, broken yet all he wants to do is piece her back together. Together, they learn that life does go on. Linstead AU.

Just a one-shot...A different twist on Roman's Return. #Burzek

AU Kim Burgess left Chicago years before, to break away from her abusive husband. She reaches out to the one person she knows will always help her Adam Ruzek

A one-shot requested by @pdshalstud

Hailey & Jay are such great partners and I'm definitely seeing the chemistry between them, wouldn't mind seeing them get together eventually. I'm a sucker for slow burns. ANYWAY these are going to be one shots of either new stories or add on's to episodes where I felt something was missing. (Probably a lot of hurt/comfort and whump hehe). Hope you enjoy!

It had been seven months since Mouse had shocked her into silence in the district parking lot. Six since Terry had died and Jay had fallen apart. Five since Erin had found the courage to ask Jay the question that had been slowly building up inside her. Five months since everything and nothing had changed. Sequel to Fluidity. Second in the States of Matter Series.

A young IT girl gains the attraction of one Sgt. Hank Voight. District 21 will make an appearance. Do not own anything. Just my OC. Rated M for safety. Even some of 51 are in this story from time to time.

based off the prompt from anonymous user: This might be too close to the last halzek prompt but if not, would you consider writing the mid season finale where Jay gets shot but with him and Adam dating? I always think about what a worried mess Adam would be from finding him, getting him to the hospital, and then waiting for news. Halzek

"As long as I have you on my side," she says. His lips curl up in a smile as he continues to look down at her. "Hailey, I am always on your side. Whatever affects you, affects me, too."

"alright, so answer me this. hypothetically, if hailey was to go home with, oh, i don't know, severide or something, would you be completely okay with that?" - prompt: the whole gang is at molly's having a great time until will halstead corners jay about his relationship with hailey and advises him to take his girl home.
