NBC warned fans that the Chicago Fire season 14 finale would leave them breathless, and the ending of the episode most certainly took our breath away.

Throughout the finale, it was clear we were building up to a major moment as the episode cut back and forth between the present time and hours earlier. By the closing moments of the finale, we finally returned to the present day as 51 responded to a building fire and raced into action. As the clips from earlier in the episode indicated, the call quickly went south, and Pascal tried to order an evacuation from the building when it became apparent that the roof was going to collapse; however, the call came too late.

In the closing moments of the season, the building went up in flames, and the roof collapsed with Severide, Cruz, Mouch, Capp, and Tony all trapped inside. Meanwhile, as Truck 81’s members attempted to flee the roof and make their way down to the ground via the ladder, Kidd, Vasquez, Herrmann, and Ballard were caught in a blaze of fire, which engulfed them as the episode cut to black.

The finale was one that is sure to bring up memories of Chicago Fire season 2, which ended in a similar manner, with the fates of all of the show’s first responders up in the air. That finale ended up resulting in the death of paramedic Leslie Shay in the season 3 premiere, which is why fans are worried that someone could be leaving Chicago Fire after the explosive finale.

There is a very real possibility in which at least one character will not survive the fire and perish in the season 15 premiere. The show has not killed off a core member of the team in a few years now, and we’re due for a shocking and major death. Due to the nature of the finale, there are several characters whose futures are up in the air on Chicago Fire, but there are five characters we know for certain will be back next season!

Let’s start with the three characters who were not in the fire and therefore marked safe. Violet, Novak, and Pascal were all outside of the fire by Truck 81, which means that the trio are not in any danger following the explosion and roof collapse. Unless the show decides to throw a random curveball our way when the season arrives and we learn that one of the three characters were injured after the fact, all three should be back and aren’t ones fans need to worry about.

Fans can also mark Severide and Kidd as safe. While Severide was inside the building when it collapsed and Kidd was among those on the ladder when the fireball engulfed them, the duo are not in any danger. This is evident in the fact that both Taylor Kinney and Miranda Rae Mayo have inked new deals to return for season 15.

With Mayo and Kinney both signed on to return for season 15, this means that Severide and Kidd are not in any real danger and will survive the events of the finale. This is sure to be a major relief as the pair remain a central part of the show and are among the fans’ favorite characters.
