The trailer for Chicago Fire season 12 finale and departed the series.

Per the TV Promos YouTube channel, the trailer depicts the return of Deputy Commissioner Boden who states, “Last night was every firefighter’s worst nightmare,” as the trio of Stella, Severide, and Dermot Mulroney’s Chief Pascal stand together, concerned. Clips of a destructive house fire appear to play in reverse, as Boden confirms that he wants to know exactly what happened, and that all he is after is the truth. Check out the trailer below:

What This Means For Chicago Fire Season 13

The Season Has Been Grueling So Far

The trailer suggests that Chicago Fire season 13 is looking to continue its theme of heavy drama, with this episode (and tragedy) coming off the back of an emotionally charged couple of episodes following the shocking death of Monica Pascal - Chief Pascal's wife - in a car accident in episode 16. The time for grieving looks to have come to an end for the firefighters at Firehouse 51, with Boden's arrival and another shocking accident to contend with. This continues the season's theme of weighty drama, and could have ramifications for the remainder of the season.

Boden's return to Chicago Fire comes after his emotional departure, but his return may not be welcomed by everyone, especially as he is looking into potential wrongdoing surrounding the accident.

Chief Pascal has been on the verge of a breakdown following his wife's death, and the accident adds more stress - this is something Boden will seek to uncover. There is no question this has been a challenging season for Chief Pascal, and things are not going to get any easier with Boden breathing down his neck. The return of Boden as Deputy Commissioner will be welcomed by viewers, and, given that he was once the chief himself, he will have a unique insight into the firehouse that could help him to carry out his job more effectively.

Our Take On Boden's Return & The Latest Accident

Events Are In Motion That Could Shape The Show Beyond This Season

Boden's return to Chicago Fire comes after his emotional departure, but his return may not be welcomed by everyone, especially as he is looking into potential wrongdoing surrounding the accident. His search for the truth is likely to ruffle feathers and could even result in someone losing their job, so the stakes are high for those in Firehouse 51. This is a plot point that could spread to Chicago Fire season 14, and viewers could be seeing more of Boden in the future.
