Chicago Fire showrunner Andrea Newman has teased how there will

be fallout from season 12’s Severide (Taylor Knney) and Damon (Michael Bradway) cliffhanger,

indicating a complex relationship moving forward. At the end of the previous batch of episodes,

Chicago Fire season 12 revealed Severide and Damon are brothers, with Benny Severide (Treat Williams) confirmed to be their father. This came from a confession from Damon, potentially bringing up the old complicated relationship Severide had with his now-deceased dad. It also sets the stage as something they’ll both need to wrestle with in season 13.

Speaking with Entertainment Weekly, Newman explained the fallout from Damon’s revelation to Severide about them being brothers in Chicago Fire season 13. The showrunner explains how the news will bring the Lieutenant back to his past, having him explore his relationship with his father and family through a new lens. She also hints at events transpiring between the pair in early episodes, meaning it won’t be too long a wait to see how the news impacts them. Check out what Newman had to say below:We kept feeling like this is haunted season 13. It’s kind of like people’s past ghosts coming back. That’s very true for Severide, where he’s worked really hard to put his father in the rearview mirror and become his own firefighter. So to suddenly have Benny’s son, his half-brother, appear in his life, it makes him have to re-explore all of that stuff. So it brings up a lot for Severide and that relationship is complicated and juicy and there’s lots of stuff that will play out between the two of them early on.
