Platt: If she comes back.
Halstead: What are you talking about?
Platt: The feds have a really sneaky way of holding on to good people. They make them wear nice suits, and they pay them really well.
Halstead: Well, Hailey doesn't like nice suits.
Platt: Uh-huh, I'm sure she doesn't. You miss her, don't you?
Halstead: Yeah, she's my partner.
Platt: Of course.
