Chicago Fire aired the first part of a crossover with Chicago PD this week. Find out what happened in our Chicago Fire season 7, episode 15 recap.

This week’s Chicago Fire was one part of a One Chicago crossover with Chicago PD, and as such it had plenty packed into it!

Wednesday’s episode “What I Saw” put firefighters on the hot seat and Joe Cruz (Joe Minoso) in the middle. When apartment building lockboxes were being broken into by robbers, firefighters were the primary suspects—so Cruz went undercover to investigate who could have turned and why.

Meanwhile, Stella Kidd (Miranda Rae Mayo) became the latest person to find a love interest while on a call, and her having a new potential romance did not go over well with Kelly Severide (Taylor Kinney). Oh, and the Big Bad came back to cause problems for everybody!

A felonious firefighter?

Everything kicked off with the whole team responding to one more massive apartment building fire, but the situation was infinitely worse this time because all of the keys that would allow the firefighters access to burning apartments had been stolen! Somebody had gotten into the lockbox and the only people who could do that would be firefighters, as each company had a key.

Eventually, our heroes forced entry to the apartment where the fire was burning and rescued the man trapped inside, who wasted no time in showing up to thank Stella for saving his life. And, unsurprisingly, asking her on a date. At first dismissing his interest as just a “rescue crush,” Stella reluctantly agreed to have a drink with Keith if he turned up at Molly’s. That’s some pretty quick chemistry!

But everyone else was worried about the lockbox key and what it was being used for, including Fire Commissioner Carl Grissom (a finally returning Gary Cole). Grissom strode right into the house on a mission, saying there’s “some cop [in] the Intelligence Unit” looking to mess up the department’s image. As if on cue, Hank Voight (Jason Beghe) was already there along with Jay Halstead (Jesse Lee Soffer) and Hailey Upton (Tracy Spiridakos). Not hard to guess who Grissom was referring to, is it?
