We should forget it ever happened. What? You sleeping with me...
MEREDITH: "We should forget it ever happened."
DEREK: "What? You sleeping with me last night? Or you throwing me out this morning? 'Cause both are fond memories I'd like to hang on to."
MEREDITH: "No, there will be no more memories. I'm not the girl in the bar anymore and you're not the guy. This can't exist. You get that, right?"
DEREK: "You took advantage of me and now you want to forget it?"
MEREDITH: "I did not take-"
DEREK: "I was drunk vulnerable and good looking and you took advantage."
MEREDITH: "Okay. I was the one who was drunk and you are not that good looking."
DEREK: "Maybe not today, but last night I was very good looking. I had on my red shirt, my good-looking shirt, and you took advantage."
MEREDITH: "I did not!"
DEREK: "Would you like to take advantage again, say Friday night?"
