With NBC‘s announcement of its winter 2024 schedule came the news of the returns of all three One Chicago shows, set for Wednesday, January 17. But just based on where Fire, P.D., and Med left off, as well as news between seasons, we’re expecting some shake-ups throughout the universe.

Med said goodbye to original cast member Nick Gehlfuss, with the ED losing Dr. Will Halstead as he headed to Seattle and reunited with ex-fiancée Natalie (Torrey DeVitto).  Both Fire and P.D. ended their seasons with one of the main characters in the hospital: firefighter Mouch (Christian Stolte) after being hit with shrapnel on a call, and police officer Ruzek (Patrick John Flueger) after being shot when his undercover assignment went sideways. Those two shows are also going to be saying goodbye to longtime cast members — Tracy Spiridakos from P.D. and Kara Killmer and Alberto Rosende from Fire — at some point in the upcoming seasons.

Below, we’re taking a look at the major changes we expect to see in winter and spring 2024 across the One Chicago shows.

Chicago Med: The ED Without Will

The hospital just isn’t going to be the same without Will, especially considering the ED lost another of its original docs, Ethan Choi (Brian Tee), earlier in the season last year. (That’s not to say we don’t like the new characters who have come in to replace the originals.) Who will step up to be the thorn in Sharon’s (S. Epatha Merkerson) side?

Chicago Med: A New Layer to Charles

Season 9 will introduce a new doctor, Mitch Ripley (Luke Mitchell, pictured above on Agents of S.H.I.E.L.D.), who has “a troubled past” and history with Dr. Charles (Oliver Platt). What will this reveal about Charles? And how will this new doctor (whose name could change) shake things up in the ED?

Chicago Fire: Severide's Return

Taylor Kinney took a leave of absence mid-Season 11, but he’s set to return for an unknown number of episodes this winter. Is Severide going to be back for good and have to see if he can just slot right back in at 51? Cruz (Joe Minoso) has been doing a great job filling in as Squad leader in his absence. Is he just back on a temporary basis, and 51 will have to figure out what it means that he won’t be coming back for good? What will this mean for his and Kidd’s (Miranda Rae Mayo) marriage?

Chicago Fire: Fallout of Mouch's Injury

At first, it looked like Mouch would be okay; after all, he wasn’t shot, though he was in the hospital, recovering from shrapnel that had to be removed. However, while Herrmann (David Eigenberg) was visiting him, he suddenly started bleeding out, and the season ended with his fate unknown. Will 51 lose one of its veteran firefighters? If not, will this cause Mouch to possibly decide it’s time to take a step back? How will the rest of the firehouse be affected?

Chicago Fire: Sylvie Brett's Exit

At first, we were wondering how Fire would resolve Casey’s (Jesse Spencer) proposal, given he lives in Oregon and Brett’s in Chicago. But with news of Killmer’s exit, that’s not looking quite as difficult anymore. Still, will she say yes? Will she choose to move to be with him? Could the drama choose a more shocking exit and kill her off? Whatever happens, it’s sure to affect the entire firehouse; she’s been part of the 51 family since Season 3.

Chicago Fire: Blake Gallo's Exit

The firehouse is also losing a firefighter, with Rosende’s last episode as Blake Gallo set for the Season 12 premiere. If he’s killed off during a call, that would surely affect the rest of the first responders for episodes to follow. If he chooses to leave on his own, depending on how and why, it might make things a bit easier going forward. Either way, it’s another change for 51, one that will affect Kidd the most as the lieutenant on Truck.

Chicago Fire: 51's New Paramedic & Firefighter

However Brett and Gallo are written out, Violet (Hanako Greensmith) is going to need a new partner in the ambulance and Truck a new firefighter. Will there be floaters to start? Will it be someone to take over as PIC (paramedic-in-charge)? Will Violet be promoted? Will the firefighter be more experienced or another candidate (as Gallo was when he was introduced)? How will these people not only get along with Violet and those on Truck but also fit in at 51?

Chicago P.D.: Hailey Upton's Exit

One season after half of Upstead left, Spiridakos will be exiting as Detective Hailey Upton, and there are a few ways she could be written out. Upton and Halstead (Jesse Lee Soffer) could be reunited, she could choose to leave the CPD, or she could be killed off. However it happens, all of Intelligence is going to be affected.

Chicago P.D.: Fallout of Ruzek Being Shot

After the Season 10 finale, it was Flueger whose future with the show seemed like it could be up in the air — and that’s still possible! He was shot and still in the hospital last we heard, and we’ll have to see if he recovers, what that means for him — and Burgess (Marina Squerciati) — and what his future at Intelligence looks like, if he survives.

Chicago P.D.: A Possible New Team Member

With the loss of Upton — and Halstead last season — the team needs some experienced blood. (And there are enough male members of Intelligence now.) Who will come in? Will this person fit with the rest of the unit? Be like Sergeant Hank Voight (Jason Beghe)? Be by-the-book?

    Please don't kill off Sylvie Brett Please have her to say yes to Matt Casey's proposal and for her to move away with Matt Casey back to Oregon to rise that family the way Matt Casey wants to rise them happily married. How about a new love interests for Violet someone like Evan Hawkins instead of Sam Craver who wasn't really interested in Violet in that way he's interested in Stella Kidd Serride remember hopefully Serride will be back. In Chicago Med what about Forster remember her in Chicago Fire? In Chicago PD what about a new love interests for Kevin Atwater or Benjamin Torres? And if they kill off Adam a new and a better love interests and pick for Kim Burgess, don't kill off Hayley Upton Halstead please don't.

      Severide is back and Foster can’t return because she became a Doctor. Carver may be interested in Stella but Stella loves Severide. A love interest for Atwater is a great idea. We haven’t seen much of Torres so we will have to see where his story goes. And I have no worries that Ruzek won’t make it and he will be with Kim. I’m not sure about Upton but I hope they don’t kill her off, the Chicago shows have already had a pretty tough time this past season.

        Erica Brodie

        To be honest I don't want Adam and Kim together romantically again and again and again they're on and off romance was driving me crazy and I don't care if Kim Burgess had an angry management problem and the only way that's she's cool unless she takes medicine it was the way that Kim Burgess treated Adam Ruzek for awhile now and each time she gets back together romantically again she treated him like dirt. I still don't truly believe that Kim Burgess truly loves Adam and this is one of her acts that she plays with Adam liked she has before. Adam deserves better than Kim Burgess and the writers shouldn't have gotten them back together romantically again and again and again. They've should of been sent in new love interests for them both. I know Forster a doctor that's why I've said what about adding her to Chicago Med as one of the new doctors? Kidd loves Serride and Serride loves Kidd by ghosting each other. Yes Torres needs to be on the show he's a good cop kind of reminder me of Vanessa remember her because her past

          No one seems to remember that Kidd apologised for what she did and Severide hasn’t returned to know how he will make up for his not quite ghosting her. He didn’t tell her about his new assignment with ATF but did vaguely explain it to her. People are human and they make mistakes, no one is perfect. And it doesn’t mean that they don’t love each other. Both the actors who play Ruzek and Burgess are just as frustrated as fans are with how they had them play their respected parts when it comes to their relationship. Patrick Flueger even told the writers if you aren’t going to keep them together and you break them up again “please don’t have them try again. Let’s face it the writers have had them go back and forth for 10 seasons enough already. I agree the writers had Burgess character be horrible to Ruzek character. But the writers need to give these characters and Severide/Kidd characters a break for a while and let them be happy for a change.

    Yep, I’ll bet they bring Antonio back to Chicago PD and MATT CASEY’s first love interest on Chicago Fire…that left to do mission trips in South America… these two experienced past coworkers would each be a good match … to bring forward the two series, from their potential losses…

  4. E

    Erica Brodie

    Yes please bring back Antonio Dawson

  5. E

    Erica Brodie

    That's what I've said about Adam and Kim's romance between them enough is enough already

  6. Y

    Yeah, I said it

    Um, I'm not gonna miss Brett, her character seemed too clingy, too soft for me. I'm not going to miss Upton either, I tried to like her character I really did, but I couldn't. So both these characters can enter the dustbin of history 🤷🏾‍♀️. Now for the Burzek's.....PLEASE for the love of Gawd, give them some happiness. Enough with the shootings, beatdowns ENOUGH...just let "Adam and Kim" live together with their daughter in peace, love and happiness.....tis the season after all 😁
