Halstead: Why'd you propose?
Hailey: Because I want to be with you. I want us. I want to know that I can have normalcy and stability in my life -- that no matter how bad things feel, at the end of the day, things will be okay because I have you. Halstead: Are you sure it wasn't just Kim? That you saw what happened to her and--
Hailey: I don't know. Maybe. But why does that matter? I love you, more than I ever thought possible. Maybe it took Kim getting shot to get the courage to tell you that.
Halstead: Yes.
Hailey: What?
Halstead: I love you, and I've known since, I've known for years that I wanted it to be you and me always. Hailey, will you marry me?
Hailey: You don't have to do that, I already did the proposal part.
Halstead: Well, I'm old-fashioned, okay?
Hailey: Yes! Yes, I will.
