On the scene of a restaurant fire in Episode 13 ("Never Say Goodbye"), Damon went ballistic on an abusive father who was causing issues for his kid. Kiddwas temptedto kick Damon back to the floater pool, but staff shortages prevented it.

“Iwanted to answer the question that you asked me last shift. About why I lost my cool on that call and why Ireallycame to 51," Damon explained."That guy at the restaurant, the father,hewas being meanandhe wastreating that younger kid like dirt.And I had a father like that, too. His name wasBenny Severide."

Severide was floored by this news — but before Chi-Hards could find out what Severide thought about the evelopment, the season faded to black.

Benny Severide (Treat Williams) had been a firefighter at Firehouse 51 with Chief WallaceBoden(Eamonn Walker) before he transferred toCFD'sarson investigation department. He had been estranged from Kelly Severide for years prior to Season 1 because he was a notorious womanizer who did very little parenting of Kelly.

The two reconnected toward the end of Season 1, though Kelly was not particularly excited to spendanytime with the man.

Still, starting in Season 2, Episode 3 ("Defcon 1"), Kelly began asking for Benny's help on fire-related cases. In Season 2, Episode 5 ("A Power Move"), Kelly learned that Benny had an adult daughter — and he had a half sister he'd never known about.

In Season 3, Episode 18 ("Forgiving, Relentless, Unconditional"), it was revealed that the younger Severide had spent some of his teen years living withChicago Med's April Sexton (Yaya DaCosta)because he didn't want to be in his own home after his father had cheated on his mother with a teacher from his school.

It was revealed in Season 7, Episode 6 ("All the Proof"), that Benny had suffered a stroke and died.

In Season 2, Episode 5("APower Move"), Severide witnessed his dad embracing a young woman and was annoyed, instantly assuming that the womanizing Benny was cheating on his current wife.

In Episode 7("No Regrets"), Severide visited the young woman he saw Bennywith,and made a discovery that left him gobsmacked: The woman,Katie Nolan (Brittany Curran),wasn'tBenny'smistress but his daughter (and Kelly's half-sister).

In the same episode, Severide confronted his father about Katie, and Benny finally apologized for his neglectful parenting.Theapology was long overdue andconcluded with Benny insisting that Severide get to know his sister, Katie.

Initially, Katie had major hold-ups about spending time with Severide. In Episode 8("Rhymes with Shout"), Severide expressed interest in connecting, but Katie shrugged him off, fearinghe'dabandon her just as Benny had.As Severide began to leave, he told herthat hewas nothing like their father.

In Episode 9("You Will Hurt Him"), Severide went above and beyond to show Katie how much he wished to be a part of her life. He was the sole attendee of her graduation from culinary school and even threw her a graduation party. They continued to build their bond throughout the season, growing even closer after Severide rescued her from a harrowing kidnapping in Season 2, Episode 14 ("Virgin Skin").

However, she left town in that episode to stay in Chicago and recover from her traumatic experience.

She returned once — for Benny Severide's funeral in Season 7, Episode 7 ("What Will Define You").

Season 4marked the introduction ofthe passionateStella Kidd(Miranda Rae Mayo) toChicago Fire.Seasons later, she would becomeSeveride'swife and overall ride-or-die. At the time, though, Stella was dealing with her recent divorce from her ex-husband Grant, a struggling addict.

The two had an instant flirtation, but Severidedidn'tmake his move until Episode 21("Kind of a Crazy Idea")when he kissed Stella atMolly's.

In the Season 4 finale, Severide and Stella took their budding romance to the next level by hooking up at her apartment.The romance was instantly ruinedfor viewers, who could see that, unbeknownst to the couple, Grant had broken intoStella'shome and was watching the lovers from the closet while holding a knife.

In the Season 5 premiere,Grant attacked Stella outsideofMolly'sover her romance with Severide — who naturally saved the day. Stella, however, refused to press charges, instead insisting that her ex go to rehab. Her decision ended the budding Stellaride romance (temporarily, at least).

In Season 6,the sizzling chemistry between Severide and Stella became even more apparent after shewas kickedout of her apartment building and he allowed her to crash at his place.

The roommates constantly struggled to dampen their attraction for each other — and ultimately, Stella swooped in for a drunk kiss in Episode 6("Down Is Better"). Severide stopped her before she could land the smooch, gently telling her,"Not like this."

Stella and Severidedidn'tlast long as just friends before they cast aside their doubts. In Season 6, Episode 15("The Chance to Forgive"), Stella and Severide agreed they were firmly dating, which complicated their"totally blasé"roommate agreement. Stella decided to move out to allow their relationship room to grow.

In the Season 6 finale, Stellaride fans finally saw Severide call Stella his girlfriend.

Severide'sgrief over hisfather'sdeathled him to create distance from Stella in Season 7and,after being effectively shut out of his life, she decided to end the relationship, initially catapulting Severide into further turmoil.

He then spent significant time working on himself, assessing his tumultuous relationship with his father and his tendency to run from those he loves the most.Severide'squest for self-actualization culminated in a visit to hisfather'sold cabin in the woods. After missing a few shifts at the firehouse, Stella suspected Severide had gone toBenny'scabin and visited him tomake surehe was okay.

Upon arriving, Severide confessed to Stella that he understood whyshe'dbroken up with him because she deserved a better man. He then revealed that he intended to do whatever it took to become that better man, leading to an emotional reunion.

One of the best developments fromSeveride'semotional growth onChicago Firewas his slow-burn romance with Stella becoming a bona fide relationship.

In Season 8, Episode 12("Then Nick Porter Happened"), Stella finally moved back in with Severide, and fans finally got to see the two kick back and relax within their relationship rather than constantlysnuff out fires in it.

In Season 9, Episode 15("AWhite-Knuckle Panic"), the two took their relationship to the next level whenSeveride proposed to Stellain the midst ofaddressing a life-threatening building fire.

“Idon’twant youto ever leave me,"Severide confessed before popping the question."Stella Kidd, will you marry me?”

“Hell yeah,"she said.

Stella experienced some natural engagement jitters in Season 10 ofChicago Fire, even taking some time away from the firehouse. Severide was concerned about why she was so distant, but soon enough, Stella came clean about her anxietiesandthe two learned how to better communicate from the experience.

Surrounded by all of their Firehouse 51 loved ones,Stellaride got marriedin the Season 10 finale.

In Season 11, Severide took a time-out from Chicago, leaving his friends, colleagues, and even his wife guessing about what might have happened to him.

AfterSeveride'sinterest in arson investigation was sufficiently sparkedinSeason 11 ofChicago Fire, he received a call from theCFD'sOffice of Fire Investigation Captain,Tom Van Meter(Tim Hopper). In Season 11, Episode 14("Run Like Hell"), fans learned Severide had received an invitation to“the best arson investigation training program in the world"— which sadly happened to belocated in Alabama.

Giving Boden just oneday'snotice, Severide left to pursue his passions in arson investigation, bidding farewell to his wife, Stella Kidd— who supported his career but missed him dearly.

In Season 11, Episode 21(“Change of Plans”),Joe Cruz(Joe Minoso) discovered that, despiteSeveride'scontinued absence, he was no longer at the arson investigation program in Alabama. Instead,he'dbeen draftedfor an ATF investigation in an undisclosed location... but had disclosed none of that to his wife, Stella.

After getting vague answers from Severide about his whereabouts and gaining no clarity on his future in Chicago, Stelladecided to take matters into her own hands in theSeason 11 finale.

"Iam taking the next few shifts off,"Stella told Sam Carver (Jake Lockett) while swiftly packing her bags."I'mgoing to get my husband and bring him back to Chicago."

Severide had returned to the Windy City by the Season 12 premiere("Barely Gone").

After Stella and Severide navigated their trust issues in Season 12, they came out of their marital struggles — and as colleagues — stronger than ever.

Along the way, Severide started thinking about what it would look like to add a little one to their family soon.

In the Season 12 finale, Severide told Stella that he'd been thinking a lot about starting a family. Stella was shocked by the confession, largely because a pregnancy would complicate her ability to bumrush burning buildings. Severide explained that he knew it was a bigger decision for Stella than it was for him, but wanted to let her know he'd been thinking about it "a lot."

Shay was Severide's best friend, his colleague, and his roommate. Shay was a lesbian and asked him to help her conceive and co-parent a child in Season 1,Episode 18 ("Fireworks"). In Episode 19("A Coffin That Small") he accepted. However, they discovered that their efforts had not resulted in a pregnancy in that season's finale ("A Hell of a Ride") — and that Severide's ex-girlfriend was pregnant with a baby he believed to be his. (He ultimately discovered in Season 2 that he was not that child's father.)

Shay and Severide, however, ended their roommate situation over his belief that he and his ex could work things out for her child.

In the Season 2 finale ("Real Never Waits"),Shay and her partnerGabby Dawson(Monica Raymund)were working to help a civilian during a firewhen an explosion went off.

Shay suffered from a severe head injury as a result, falling to the ground unconscious. In a moment of sheer panic, Severide and Gabby tearfully attempted to revive their friend.

Picking up six weeks after the devastating building fire, Season 3 ofChicago Firebeganon asombernoteas the audience learned that Shayhadn'tsurvived. Firehouse 51 struggled to move on from thetragic death—Gabby and Severide more than most.

After Shay's death, Severide took his drunken grieving to Las Vegas in Season 3, Episode 6 ("Madmen and Fools"), where he met Brittany Baker (Serinda Swan), who was grieving her sister's death.

Upon returning to Firehouse 51 in Episode 7 ("Nobody Touches Anything"), Severide told his shocked friends that he had married Brittany in Vegas.

The pair ultimately called off their marriage in Episode 9 ("Arrest in Transit") after agreeing to deal with their actual issues rather than distractingthemselves with a half-baked union.

Severide embarked on a romance with Anna Turner (Charlotte Sullivan) in Season 5. After Severide reconnected with his firefighter-buddy-turned-doctor Jeff Clarke, hewas askedto enroll on the bone marrow registry in Episode 8("One Hundred"). Severide agreed — a life-altering choice that led him to meet a bone marrow recipient, Anna.

Severide learned Anna was fighting leukemiaandshe'dpreviously struggled to find a bone marrow match. Severide, however, proved to be a perfect match in more ways than one: After receivingSeveride'sdonation, she both seemed to make significant progressandthetwo fell in love, ultimately dating throughout the season.
