Last night's episode of "Chicago Fire" left fans reeling with a surprise death. For spoilers on what's to come and the impact of the loss of this character, read on. If you have not yet seen last night's episode, be warned, this article contains major spoilers about what happened last night.

In a surprising and saddening twist, firefighter Rebecca Jones, played by Daisy Betts, committed suicide on last night's episode.

Executive producer Matt Olmstead spoke with TV Guide about how the show will progress, and how the other firefighters will press on in the face of such a tragedy.

"Her taking her life not only gave us the impact of an episode out and this next episode which is very emotional. ... It's Boden's first speech to the troops, which is, in that line of work ... you have to deal with loss a lot more than other lines of work and you prepare yourself or you toughen up your skin towards it," he said.

"But when it comes to a fellow firefighter taking their own life, you're never really prepared for that," he added.

Olmstead went on to discuss how Rebecca's death will influence Dawson.

"It impacts her because she's, at first, knocked sideways as everyone else is and then looking to blame someone and in this case, it's Jones' dad. Then, she realizes that's not going to solve anything," he said.

"So, for her going forward, she's recommitted to being a firefighter to, not only the memory of Jones but to prove to other people that a woman can do that job," he added.
