Chicago Fire returned to NBC on January 8 with a winter premiere centering around Joe Miñoso’s character Cruz. New installments air

every Wednesday at 9 p.m. ET, and season 13, episode 10 will debut on January 22. “Chaos Theory’s” official synopsis reads: “The team

responds to a crisis at a community centre; Severide is forced to investigate one of his own squad members; Kidd helps a teacher going through a post-incident spin-out.”

The mid-season premiere, “A Favor,” saw Cruz deal with the aftermath of Junior’s threat to his career. Star Joe Miñoso teases that the storyline will continue throughout upcoming episodes, but draw to a conclusion before the One Chicago crossover on January 29. The highly-anticipated event marks the first time all three series have crossed over in six years, and Miñoso shares his excitement over working with fellow Chicago cast members.

Joe Miñoso: Poorly. He’s going to make some decisions that really put him in some hot water, and then the ramifications of that are going to really show up in Episode 10. Cruz is, and always will be, concerned about protecting his family first and foremost, and he will go to any lengths to do that. And so unfortunately he’s going to get tangled up in a big old mess, but let’s hope he comes out the other side of it. I will say it will not be unscathed.

Joe Miñoso: I think, especially after becoming a father and now really having a taste for leadership, he’s been the acting lieutenant on Squad 3 for a couple of years now, that’s always in the back of his mind, especially as a father who has to take care of two kids who will hopefully end up going to college one day. Money is always a thing he’s thinking about, but I think, right now, there was some great stuff between Severide and Cruz early on in the season that I think brought them closer together.

I think Cruz just wanted to feel in that moment when he was talking about taking the test and leaving the firehouse. I think he just wanted to feel needed or wanted. He felt a little bit like he was disrespected for the work that he did when Severide wasn’t around. He feels that those wounds have mended between him and Severide. Right now, he’s, I think, happy to stay. He’s a family guy. He loves his family, he loves to be around his family, and 51 is, without a doubt, his family.
