Stargate SG-1, Season 10

Col. Carter is in an alternate universe.

Lt. Col. Carter:
I'm not who you think I am.

Dr. McKay:
Oh my god, you're a lesbian, is that what you're trying to tell me?

Lt. Colonel Carter:
What? No - McKay!

Lt. Col. Carter:
The Rodney McKay I know wouldn't back down from a challenge. He is one of the most forthright, courageous… and selfless men I have ever met.

Dr. McKay:
[preening] Hmm. [realizes] Aw, you're making that up, aren't you?

Lt. Col. Carter:
Most of it, yeah.

Lt. Col. Carter:
The Rodney I know is a master of subtle persuasion.

Dr. McKay:
Huh. Oh, you're lying again, aren't you?

Vala:
Hey, what was I like in that reality?

Lt. Col. Carter:
[uncomfortably] You were in jail.

Vala:
Not again!
