Big Changes Are Coming For One Chicago

The first two shows inDick Wolf’s One Chicago universehave been through massive changes in the last two years. Focusing on just its latest cycle, however, viewers can expect things will be very different for Firehouse 51 and Intelligence when the new year finally arrives. ForChicago Fire season 13, Boden’s departure will definitely be a major factor, as proven by the trailer. Beyond that, however,other changes are coming for the firehouse, particularly for Kelly Severide. Aside from expressing his desire to start a family with Stella Kidd, he was also unexpectedly introduced to his half-brother, Jack Damon.

As forChicago PDseason 12, the biggest change comes on the heels of Hailey Upton’s departure from Intelligence. Between this and his near-death experience in the season 11 finale,Voight is looking at an uphill battle when he comes backthis September to face his trauma. Interestingly, this situation is not new for the character, considering the many tragedies he has experienced in his lifetime. However, it may be time for him to properly deal with all this pent-up grief so he can move forward with it. Otherwise, he risks being ineffective in his job.
