Miranda Rae Mayo and Taylor Kinney are set to reprise their roles as Stella

Kidd and Kelly Severide in Chicago Fire season 13, but a new video makes me

believe that one of them will have a bigger role than the other. The NBC

prodedural drama centers around a group of firefighters and paramedics working at Firehouse 51 in Chicago. Chicago Fire, which is going on its thirteenth season, has been so successful that it spun off three other TV shows in the One Chicago franchise. However, its longevity also means that the cast has significantly changed over the years.

The cast of Chicago Fire season 13 certainly doesn’t look the same as it did in season 1. There are still a handful of familiar faces, including Kinney as Severide, David Eigenberg as Christopher Herrmann, Christian Stolte as Randall “Mouch” McHolland, and Joe Minoso as Joe Cruz. However, most original cast members have exited the series, with the latest being Eamonn Walker’s Boden leaving after the Chicago Fire season 12 finale. As a result, the NBC procedural drama is seemingly replacing Chief Boden with someone who has been on the show for a long time.
