Dr. McKay and Lt. Colonel Carter in “Unfinished Business”

But um, first, I just wanted to thank you for being there for me recently in a time of great personal need. Well, actually, you weren't there— I was alone in the dark, but um, you know, it sure seemed like you were.

[suspiciously] Are you telling me one of your fantasies?

No it was a hallucination, I had a concussion, I was trapped in the back of a sinking Jumper and my mind conjured you up as a means of survival, it's what you would do in my situation. You saved my life

OK well, that's… sort of nice.

Mmm. Yes it was.

Was I naked?

[slightly embarrassed] Partially.
