Upton: Are you insane? There are a thousand ways this goes wrong. A thousand ways you end up on the wrong end of this. If IRT came to question you that means there's discrepancies in your story. You are risking your career, jail time.
Ruzek: I know.
Upton: Your life. For what? Some half-ass notion of loyalty?
Ruzek: It is not a notion. It's Antonio. It's Voight. It's our unit. It's OUR unit. And I'm going to protect it every time. Every time! That's who I am. Why do you have a problem with that?
Upton: I don't have a problem with that. I have a problem with something happening to you.
Ruzek: No, you have a problem with my damn ethics, Hailey. You always have had a problem with that. And I'm not going to talk about policing with you again.
Upton: Listen. This has nothing to do with police loyalty, it has to do with you. I care about you.
Halstead (interrupting): I can hear you guys in the stairwell. What the hell are you doing?
Upton: Nothing. It's fine, sorry.
Halstead: You cannot be having this conversation here.
