Kelly Severide
Portrayed by Taylor Kinney
Kelly Severide (season 1 – present) is the lieutenant at Firehouse 51 and the officer in charge of Squad 3.
In season 2, Severide is targeted by an arsonist twice before realizing that the arsonist is targeting firefighters. He makes the connection that the arsonist is also a firefighter, most likely Kevin Hadley, but they have no proof, until they eventually catch him in the act and he is arrested. In the episode "A Power Move", Severide spots his father Benny hugging a young woman and believes he is having an affair. Kelly meets Benny who tells him that he will succeed Boden as the new chief of fire house 51. In the episode "No Regrets", Severide confronts the young woman, Katie Nolan, who reveals Benny is her father, making her Severide's younger half-sister. Severide lashes out at Benny, who acknowledges that Severide is right about him and apologizes for not being there for him as a father. Benny decides not to take the job from Boden, and encourages Severide to get to know his half-sister.
This brief starts where responsible research should: with the source description of “List of Chicago Fire characters” as wikimedia list article. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as wikimedia list article. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q19864097. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
