Please don't let this turn into something it's not. . .
...was it when Derek 'yelled' at Meredith at Seattle Grace, and she was kinda upset when he came home that night, and then he told her that no matter what he said, he'd still come every night. Then he asked her something like, "Haven't you ever done this before?" referring to living with someone, and she said no, or something like that.
I know it's season 3, but does anyone know the exact episode?
. . .I can only give you everything I've got.
