Should You Worry If Cara Kilmer Is Leaving The NBC Show? Where is Sylvie Brett in Chicago Fire Season 10?

For the time being on vacation, Brett is taking a break from spending time with Casey.

At least we know that Brett is finally going to be back at Firehouse 51.

The show's boss Derek Haas has already noted that he wants to bring Spencer back for the finale.

So that Kilmer and Spencer, if possible, can do something for these two characters.

As we've seen over time things have to move on, even if some of the characters aren't around.

We know there's going to be another paramedic around firehouse 51

Can't predict Kara or Brett going forward this season. Just know that you will see him again this season
