NBC’s long-running hit **Chicago Fire** is known for delivering emotional and action-packed episodes, and Season

13 is no exception. As the show heads into its 12th episode, fans can expect an installment filled with high-stakes

drama, personal revelations, and a shocking return that will impact one of Firehouse 51’s strongest leaders—Stella

Kidd (Miranda Rae Mayo).

With a mysterious figure from Kidd’s past resurfacing, this episode promises to shake up her life and possibly affect her relationship with Kelly Severide (Taylor Kinney). Who is coming back, and what does it mean for Stella’s future? Here’s everything we know so far about **Chicago Fire** Season 13, Episode 12.

### Who is Coming Back for Stella Kidd?

NBC has been tight-lipped about the exact details of Episode 12, but insider sources and teasers hint that a major figure from Stella Kidd’s past will make an unexpected appearance. There are a few strong possibilities for who this could be.

First, there’s the chance of a former flame returning. Before her relationship with Severide, Kidd had a complicated past, including ex-boyfriends who left a lasting impact. Could one of them be coming back to stir up drama?

Another possibility is a long-lost family member. Stella has mentioned having a difficult upbringing, so could a sibling or estranged parent re-enter her life? Alternatively, it might be a former colleague or rival. Firefighting is competitive, and Kidd has had her share of past tensions with colleagues from other firehouses, meaning a return could bring up unfinished business. Regardless of who it is, one thing is certain: this reunion won’t be easy for Stella.

### How Will This Affect Kidd and Severide?

As the episode focuses on Stella’s past, it will undoubtedly put her relationship with Severide to the test. Over the years, Severide and Kidd have faced many challenges, but this new development has the potential to complicate their bond like never before.

Will Severide be supportive? He has always been Kidd’s rock, but if this blast from the past reveals secrets she’s been keeping, it could create tension between them. If an ex-boyfriend is involved, feelings of jealousy and insecurity may arise. Additionally, Kidd’s fiercely independent nature means she might not easily open up, leading to possible miscommunication. If the returning figure caused her pain previously, Severide might feel protective, resulting in further complications. This begs the question: will this test their relationship or strengthen it?

### Other Storylines in Episode 12

While Kidd’s past will be the main focus, Episode 12 will also feature significant developments for other characters at Firehouse 51. One intriguing storyline revolves around Casey and Brett’s future. With Matt Casey’s recent return, fans have speculated whether he and Sylvie Brett are endgame, and Episode 12 might reveal a major step forward in their relationship.

Additionally, no episode of **Chicago Fire** is complete without tense rescue missions, and a life-threatening call could push the team to their limits. It raises questions—could someone from Firehouse 51 be in serious danger? Also, viewers will see Joe Cruz grappling with his responsibilities at Firehouse 51 and his growing family. Will he manage to keep work and home life separate in this episode?

### Fan Theories: Who is Returning and Why?

Fans have been actively speculating about who might return in Stella’s life, leading to some interesting theories. One prominent idea is that Stella’s ex-husband, Grant, could make a comeback. Fans remember Grant as a troubled figure who had a complex relationship with Stella, raising the question of whether he has changed or will bring chaos back into her life.

Another theory suggests that a long-lost family member may return, as Kidd has hinted at a complicated family history. If this is the case, it could provide valuable character development for her moving forward.

Lastly, some fans speculate that an old firehouse rival could make an appearance, someone who once challenged Stella’s authority and may now create tension within the firehouse.

### What This Means for the Future of Stella Kidd

Episode 12 is poised to be a defining moment for Stella Kidd’s character. As Season 13 progresses, this episode could delve deeper into her backstory and challenge her leadership role at Firehouse 51. It will also test her relationship with Severide in ways they have not yet faced.

Will this episode mark a turning point for Stella as she navigates her past and its implications for her future?
