Chicago Fire season 12 has featured several high-profile departures, including Kara

Killmer as Sylvie Brett and Alberto Rosende as Blake Gallo. While the cast of the show is

still a large ensemble, the emotional goodbyes for many of its characters have made

this season in particular stand out. Now, NBC (via TV Promos) has released a trailer for the final episode of Chicago Fire season 12, teasing “an emotional farewell” episode for Eamonn Walker as Wallace Boden. Chicago Fire Season 12, Episode 13 Promo (Trailer) The trailer shows a variety of characters gathering to say goodbye to him, the teaser revealing how much the episode will focus on his leading Firehouse 51. Since he’s been on the series since the beginning, his departure might be one of the most emotional since Jesse Spencer’s Matthew Casey in season 10.

Why Boden’s Chicago Fire Exit Is So Impactful Chicago Fire Has Had A Rotating Cast Boden has not been on the show as much in season 12, with Casey stepping up to take on a leadership position in his absence. Not much is known about why he hasn’t been as active within the Firehouse, but it seems to have been because of something in his family. This may also be why he decides to leave, his general absence throughout the season already serving as a transition to the show continuing without him. It sets up an emotional ending, but also a mystery that won’t be clarified until the finale.

However, Boden’s absence isn’t the end of his story, as he’ll be coming back to Chicago Fire season 13 in a recurring capacity. While this means he won’t be showing up much for future episodes, it does indicate he won’t be dying or moving out of Chicago by the end of season 12. Yet that still makes his decision to leave a mystery, something that will be explored in more detail during the finale. Despite a future appearance guarenteed, it doesn’t change how emotional this next finale of the series will be.
