Grey's Anatomy Season 5 Episode 18 Quotes

Meredith: It's the not knowing that does it. Not knowing if he's ok. Not knowing if he's coming back. Maybe I've just been dumped. I mean, It's not knowing if I'm single that makes me wanna throw up all day long. You are not listening to me are you?
Cristina: Ah, sorry.
Meredith: No,no. That's okay, I get it. You've got the solo surgery and GI Joe. It's a charmed life. You don't have time for me.
Cristina: I have not had GI Joe. We've kissed a couple of times. It's like friends with benefits, without the benefits.
Meredith: Still no sex?
Cristina: Mmm mmm, not a charmed life.

Miranda: I've lost Hunt and Torres, see I sent them to get Shepherd and ... never heard from them again ... I was trying to solve the Shepherd situation for you sir, but it appears that I somehow made it three times worse.
Richard: [stares]
Miranda: So I'm telling you and my next move I believe is that I'm gonna call the police because I'm half convinced that they're all dead ... on a spit ... with an one armed man turning them into shish kabob sir ... It's my mind it just goes there.
