Hawkes: Bad judgment on my part. I didn't know anything about what Hamilton was up to. He's just somebody I hung out with. We went to undergrad together.
Mac: Sheldon, stop. This just all sounds a little too rehearsed for me. These are the lines you practiced in the back of the squad car? What will I tell my boss? The D.A.? The detective on the case?
Hawkes: You think I'm lying?
Mac: I think you're hiding something. I would prefer you treat me as a friend and not just another authority figure looking for a reasonable explanation. Look, I said this before. You can tell me anything. I would hope you'd trust that.
