The Chicago Fire Fan Favorite Who Is Returning In The Finale

The "One Chicago" franchise, comprising "Chicago P.D.," "Chicago Fire" and "Chicago Med," is fast gaining traction as a must-watch for fans of procedural drama with a soapy edge. However, given everything that's at stake in these shows, it's not terribly surprising several fan favorite characters have left far too early for our liking. As Us Weekly notes, the likes of Torrey DeVitto, Brian Geraghty and Sophia Bush have all departed the franchise over the years, much to viewers' utter and very vocal disapproval. 

Most recently, per USA Today, Jesse Spencer walked away from "Chicago Fire" after an incredible ten seasons on the hit show. Likewise, fans are concerned about Kidd following the emotional finale, while One Chicago Center points out they're going to have to wait until 2022 for new episodes of it, "P.D." and "Med" despite all the loose plot threads that are currently dangling. However, there's at least one thing to look forward to in an upcoming episode — the return of a sorely missed, fan favorite character. 

We might have lost series stalwart Casey, among many others, but beloved "Chicago Fire" pooch Tuesday is making her triumphant return in an upcoming episode, per One Chicago Center. A special festive installment of the hit procedural will see the cherished dog finally reunited with her 51 family. Tuesday was last spotted onscreen in Season 8. On-set photos show Tuesday greeting Alberto Rosende's Gallo as he chills out between calls with Daniel Kyri's Ritter and Hanako Greensmith's Violet, as well as cuddling on the sofa with Christian Stolte's Mouch. Suffice to say, Tuesday is set to bring everybody's spirits up in time for the holiday season regardless of whatever else the team has to contend with. Kidd is also slated to return alongside the adorable pooch. 

Showrunner Derek Haas previously revealed plans for a holiday special in a chat with TVLine. "Chicago Fire" has done festive episodes in the past, but they've been light on holiday cheer. That's all about to change this year, as Haas himself wrote the installment in question and promised it's "going to make the Hallmark Channel jealous of our holiday episode." Due to the way the show has aired this year, the installment in question ended up as "kind of on this island by itself." As a result, Haas and the team figured a Christmas episode would be fitting. It also presented the perfect opportunity to bring back Tuesday, which should have long-time "Chicago Fire" fans cheering.
