Could 51 be about to lose yet another key member of its cast? Well, that’s the

fear on the mind of Chicago Fire fans after the way in which the show’s second episode

ended and the promo for the show’s third episode of the season.

As the second episode of Chicago Fire season 13 came to a close, Severide sat down with Damon and made it clear: one of them has to leave 51. This omission came after Severide realized he was going out of his way to look out for Damon and their relationship was clouding his judgement leading to special treatment he would never give to others.

Earlier in the episode when responding to a call involving a woman trapped under a boat, Damon disregarded an order from Kidd and rushed right into action. While Kidd gave him the benefit of the doubt after he told her he didn’t hear the call made, Damon later admitted to Severide that he indeed heard Kidd’s order and disregarded it out of a desire of wanting to race into the action.

At first, Severide covers for Damon, but following a conversation with Cruz in which Cruz tells Severide to be careful as he knows what it’s like to have a younger brother who got the short end of the stick, and to have a desire to overcompensate with the desire to try to help them in life.

Following this conversation with Cruz, Severide comes clean to Kidd about Damon lying to her and Kidd is understandably frustrated that not only did Damon lie to her, but so did Severide. After Kidd confronts Damon, he goes to meet up with Severide after shift and confronts him about telling her to which Severide makes one thing clear: one of them has to leave 51.

As if Severide’s ultimatum to Damon at the end of Chicago Fire season 13 episode 2 wasn’t enough to make fans worry that Severide could perhaps choose to walk away from 51, the promo left fans speechless and worried that we could indeed be about to see someone leave 51.
