Richard: This is an extremely serious accusation, Meredith. Can you tell me anything?
Meredith: I-I-I can't. I'm- I'm sorry.
Richard: How many patients are we talking about here? Did this happen more than once?
Meredith: I can't say that either.
Derek: She can't say anything.
Richard: Look, we're going to unwind this, Meredith. Karev is figuring out what cases he was on when he saw you, he'll narrow down the dates and we'll know which patients--
Meredith: Nothing I did changed the trial. Uh, fire me. Do whatever you have to do.
Derek: Look, you don't get to choose, okay? (Alex knocks on the door, Richard opens it and takes an envelope from him) You don't get to decide who gets the drug or who gets the placebo. You don't get to decide what information the trial gets.
Meredith: Nothing I did affects the trial. If you don't know what I did, the trial stays blind.
Derek: The trial is over. You screwed me. You screwed this hospital. And you screwed yourself. This is your disease that we're trying to cure. (Richard is looking through the files Alex gave him) I mean, I could've picked Parkinson's...
Richard (mumbles): It was Adele.
Derek: ... or Lou Gehrig's disease, but I did this for you.
Richard: Derek, it was Adele.
