Chicago Fire is back tonight after taking another break, and picking up where two of its storylines left off. But how much should One Chicago fans read into this episode?

“One Crazy Shift” features paramedic Violet Lim (recurring guest star Hanako Greensmith) joining Ambulance 61. Violet’s addition was teased in the previous episode, as Gianna Mackey was given a chance to move up in rank at another firehouse.

(In reality, actress Adriyan Rae exited the series for personal reasons, leading to Gianna’s sudden job offer.)

With that in mind, it’s no surprise that one of the storylines here is a Violet-centric one. The show has to give more detail about her than when she was just Blake Gallo’s (Alberto Rosende) girlfriend. It also has to establish how she works with her new partner Sylvie Brett (Kara Killmer).

While Brett and Violet investigate who’s been sending the latter some suspicious and unwanted mail, the other main story in “One Crazy Shift” is also picking up from two weeks ago—it involves Matthew Casey (Jesse Spencer) continuing to recover from his latest head injury.

One Chicago audiences may recall that Casey was previously told not to take any more blows to the head, and that was before he got knocked around last time. Will he still be suffering effects of that specific incident? Or is this more of Casey evaluating his long-term health and future?

Some fans have already been speculating online that this is Chicago Fire setting up an exit story for Jesse Spencer, and it’s worth noting that there is no official word about whether he’s staying or going yet. (Any such announcement would almost certainly come after his final episode, like it did for Adriyan Rae two weeks ago.)

But it’s certainly a storyline that should have effects on his character. The series has beaten up Casey a lot over the last eight and a half seasons, so by putting that health risk back into play, it really can’t keep doing that because otherwise he would get seriously injured. And as we saw with Jimmy Borrelli a few seasons ago, if you’re not physically fit for duty, you can’t keep working.

So the writers either have to take better care of Casey (at least his head) or they’re going to write themselves into a corner.

Keep your eyes open and see how they handle this, as well as how Violet fits in now that Fire has to write her as a regular character. The rest of this season is likely a test to see whether or not the character sticks around for season 10.
