A storyline "Chicago Fire" fans have been holding on to is the relationship between Kelly Severide (played by Taylor Kinney) and Stella Kidd (played by Miranda Rae Mayo). Kidd appeared to be missing for much of the show's 10th season (via One Chicago Center). Fans were beginning to fear the worst, thinking that yet another character had been written off the show, especially when she wasn't included in the finale photos.

However, it seems that Kidd was away doing her Girls on Fire program, something she formed to try to get more girls interested in firefighting (per Showbiz Cheat Sheet). While Kinney felt abandoned by Kidd during this time, it seems to be temporary, and fans shouldn't worry.

A showrunner recently confirmed that Kidd was back for good. Derek Haas told TVLine, "Yes, she's back for good, but she has a lot of explaining to do, and it's not just explaining to Boden why she didn't immediately come back when she heard that Casey was leaving and more or less planted a flag on Truck 81, but also why she went dark on Kelly when he was obviously trying to reach her and had her best interest in mind," Haas shared. "The next batch of episodes, certainly, the driving force of them will be Stella Kidd's return to Firehouse 51 and all the offshoots of that."
