Casey: How'd you get away from him?
Sylvie: It was, uh. I wasn't going to miss my own wedding!

Severide: It's funny how we pull out cigars, and it suddenly feels like you never left.
Casey: In a lot of ways, I didn't.
Severide: It seems permanent somehow when you leave this time.
Casey: Sylvie and I will always come back to 51.

Ritter [to Casey]

We will make this right. I promise. This will be the best fish store wedding in history.
