Derek Shepherd: Dr. Shepherd? This morning, it was Derek. Now it's Dr. Shepherd.

Meredith Grey: Dr. Shepherd, we should pretend it never happened.

Derek Shepherd: What never happened? You sleeping with me, or you throwing me out this morning? Because both are fond memories I'd like to hold onto.

Meredith Grey: No, there will be no memories. I'm not the girl in the bar anymore, and you're not the guy. This can't exist. You get that, right?
