'Chicago Fire': Dawson asks Casey a life-changing question (exclusive video)

Dawson is about to pop the question to Casey. But even though it's not that question, it's still one that could change their lives forever.

After her devastating miscarriage at the beginning of this season of Chicago Fire, the couple have rarely brought up the topic of children ever since.

However, as showrunner Matt Olmstead told The Hollywood Reporter last week, all that is about to change after Dawson rescues an adorable foster child from a fire.

In THR's exclusive video from Tuesday's episode, Dawson can't seem to get the kid, Louie, out of her mind after rescuing him. She confronts the issue head-on by talking with Casey about becoming his foster parents. "I have a feeling this was meant to be," she tells him.

So what happens next? Watch the exclusive video below.

Chicago Fire airs Tuesdays at 10 p.m. on NBC.
