Harmony: Tell me something, Doctor. The place where you sleep at night, is it guarded?
McKay: I know what you're trying to do, and it's not gonna work, OK? And I'm not scared of you. You're just a kid, a bratty little kid. I couldn't care less if that you're going to be queen. In fact, nothing could impress me less! So, why don't you just cool it with the backseat act, and go back to ignoring me!
Harmony: Surely, they can't guard you all the time?
(McKay turns to look at Harmony, a disconcerting look on his face. Harmony smiles at him)
