Did someone leave the hose running at Firehouse 51 or are those our tear ducts?

After a season 7 cliffhanger that left literally every major character onChicago Firein peril, the mattress factory fire was finally extinguished in the season 8 premiere — but not without claiming one of 51’s original players.

Brian Zvonecek, better known as Otis, was badly burned in the fire and died shortly after he arrived at the hospital. And thus, original cast member Yuriy Sardarov departed the series.

Somehow through our tears, we managed to get executive producer Derek Haas on the phone to talk about Otis’ death, how Sardarov handled the bad news, and what this will mean for his best friend and roommate Joe Cruz (Joe Minoso) and the rest of the firehouse going forward.

All of that must have been rough for Joe Minoso [who plays Cruz].Well, Joe is incredible. I was there also for the last shot of the episode, which is the memorial reveal and Boden telling Cruz what Otis’s last words — in Russian — meant. … I’m watching the first take, which is this wide master shot, a sweeping crane shot where you can’t even see Cruz’s face.
