Meredith: Hi.
DEREK: [walks into elevator] "Hi. Leaving?"
MEREDITH: "80-hour limit. You?"
DEREK: "Surgery was postponed." [smiles]
MEREDITH: [pauses] "I have a dog."
DEREK: "You have a dog."
MEREDITH: "My point is, I have a dog."
DEREK: [smiles] "You have a dog. Oh, and you know what? I love dogs."
MEREDITH: "I've moved on, so don't give me that look."
DEREK: "What look?"
MEREDITH: "That look. Our look. I'm over you."
DEREK: "I'm over you, too."
MEREDITH: "You are?"
DEREK: "No."
MEREDITH: "Oh. Well, I am. Over you."
DEREK: "I'm over you too."
MEREDITH: "You just said... shut up." [smiles]
