Derek: Meredith's not a slacker.
Sadie: Ooh, I could tell you some stories.
Meredith: But you won't.
Cristina: So, Sadie you postponed your residency to work in a morgue?
Sadie: Yeah, you know, all the fun cutting, no rules. But I got bored. Starting craving blood that was actually flowing.
Meredith: And now you're here. I can't believe that you're here.
Cristina: ... Yay!
