Chicago Fire returns for its 11th season on September 21. Here’s what you need to know from its leading lady.

Where We Left Off

Finally…Stellaride made it official: Lt. Kelly Severide (Taylor Kinney) and Lt. Stella Kidd (Miranda Rae Mayo) exchanged vows in the drama’s Season 10 finale. But wedded bliss didn’t last very long, because they found an intruder at their cabin. “It’s like, can’t these two just have a honeymoon?!” Kara Killmer (who plays paramedic Sylvie Brett) asks.

Where We Pick Up

Figuring out who that bad guy is will start things off in Season 11. “We’re going to see the fallout of that,” notes Killmer, along with the question, “Are they going to be OK?” And while best man Matthew Casey (Jesse Spencer, who exited last season) came back for the wedding, Casey and Sylvie’s long-distance relationship is clearly not making either party happy.

Coming Up for Sylvie

Prepare to watch her get lost in her job for a bit. “She has the paramedicine program she created,” Killmer says. “You’re really going to see her try to make a difference in the city.” And while things will evolve for her and Casey, “you might see an old love pass through too,” Killmer teases.

    Very interested to see what happens with Stellaride and this intruder. Also how long are they gonna drag on this LDR storyline if they’re just gonna be miserable in it?? I’d rather see Sylvie be happy with a love interest on screen.

    I have a feeling the intruder in the cabin is going to be Stella's old friend who had a crush on her. If not him then it is going to be a good surprise like an old friend neither of them has seen in forever. Now on to Sylvie. Casey is gone time to move on. I never like Casey anyway. I always thought he came off as he thought he was better than anyone.

    Do you always have to define Brett in terms of relationships??? She is a strong woman and great at her job. I'm looking forward to seeing her and Mouch on the job in Season 11. Jesse has been shooting an 8-episode short series in Australia since July. A lot can happen by the end of the season at CF.

    I really hope Brett & Casey will continue LDR!! Don’t break Brettsey up.  This old love better stay far away from her!!

      I love them together, too.  However, I don't know how long they can keep up this whole LDR idea.  I know Derek is doing that, because he's leaving the door open for Jesse Spencer to return down the road.  But, that's not happening anytime soon.  Jesse's working on something else right now.  And considering that conversation they had at Stellaride's wedding about how difficult long distance has been, I worry that it may flame out.  I hope not, but I do wonder how they "evolve."  And, which "old love" of Brett's shows up?  She has a lot. lol

        I’m thinking the only old love it could be is Greg Grainger. Dawson is on La Brea, Kyle is Indiana preaching, Cruz is married, the guy who bought Cruz slamigan ( not much of a relationship), Roman moved to San Diego so I’m thinking that it’s got to be him. That would be great and I liked him and Brett together anyway.

          You're right.  I liked Grainger, just not with Brett. lol. Jon is a very handsome man, so I wouldn't mind seeing him again.  I certainly liked his character a lot better than Guero on Queen of The South. lol
