The end of season 12 brought out Damon’s secret. Of course, there were a lot of concerns that Damon would be a secret love child. While Severide was known for sleeping with a few women here and there, it was always clear that he took sexual health seriously. We always got a sense that he would use protection.
So, the idea of a secret love child didn’t make much sense. But TV shows like to bring in these soapy storylines for drama. Instead, the show opted to bring back Severide’s family another way. Jack Damon is related to Severide, but not as father and son.
The show is opting for the same storyline they used years ago, with Damon being a half-sibling. This isn’t as shocking as the idea of Damon being Severide’s son since we know Benny Severide had at least one other child, and yes, he kept that other child a secret for a while.
So there’s a huge storyline opening up for Severide as he learns more about Damon. Severide is sure to want to make sure Damon is actually his half-brother before doing anything else. Benny isn’t around anymore, and Damon’s story about Benny being abusive didn’t seem to add up.
We know Benny was tough and absent, but he has ever described the man as abusive and his half-sister Katie has never said anything like that.
