Chicago Fire’s Kelly Severide and Stella Kidd’s Relationship Timeline

Chicago Fire has been filled with red-hot romances throughout its run, but nothing compares to Kelly Severide’s relationship with Stella Kidd.

When fans first met Kelly (played by Taylor Kinney), he was a rough and tough firefighter who was known for being a ladies’ man. However, the arrival of Stella (Miranda Rae Mayo) in season 4 shook things up — and changed Kelly for the better.

The twosome has weathered many storms, including a season 9 moment when Kelly ices out Stella while she’s studying for her lieutenant’s exam.

“Of course, I know I don’t need your help with some test. I needed you to do what you do best: To tell me, ‘You got this, Stella Kidd,’” Stella says to which he replies, “This attitude of yours is exactly why I know you got this, Stella Kidd, and it’s why I know how badly I screwed up, and it’s why I’m never gonna let you go away from me again.”

Chicago Fire airs on NBC Wednesdays at 9 p.m. ET.
