What happened to Mouch at the end of Chicago Fire Season 11?
Firehouse 51 responded to a call at a power station during Season 11, Episode 22.
Domestic terrorists were trying to leave millions of people without power, but a task force led by Matt Casey is on the job.
Casey learned about the threat while he was in Portland, but he returned to Chicago when he felt an attack was imminent.
Casey also recruited Stella Kidd for the task force, giving the writers and producers an extra excuse to bring back actor Jesse Spencer for a few episodes.
The firehouse found that a fire had been started at the power station, but upon arriving, found that there were also shooters trying to harm first responders.
Casey and several other firefighters snuck into the adjoining parking garage to take out the terrorists, saving the day and the city of Chicago.
While on that domestic terrorism call, Mouch was hit by a piece of shrapnel and rushed to the hospital.
Christopher Herrmann visited Mouch at the hospital near the end of the episode, and he was in good spirits. But then the machines started going off, Mouch fell unconscious, and Herrmann discovered his friend was bleeding out.
The episode ended with Mouch clinging to life.
Viewers must tune in for the Season 12 premiere to learn if the fan-favorite character has survived.
