One of the chief concerns among Chicago Fire fans lately has been whether Casey (Jesse Spencer) and Dawson (Monica Raymund) are going to get back together. But it's officially time for fans to start worrying about more important things, i.e. Casey's life.

In The Hollywood Reporter's exclusive video from Tuesday's season finale, Casey, Voight (Jason Beghe) and Antonio (Jon Seda) meet with Chief Boden (Eamonn Walker) to discuss the prospect of Casey going undercover to get intel on Jack Nesbitt's suspected human-trafficking operation.

"Jack Nesbitt gives all firefighters a bad name," Casey tells a reluctant Boden. "If I can help, I want to help."

Unfortunately, Casey's efforts to help Intelligence could cost him big time when the wrong person sees him with the police.

Take a look at the clip from "Spartacus" below.

Chicago Fire airs Tuesdays at 10 p.m. on NBC.
