Meredith: Hey. How long have you been up?
Derek: All night. I was trying to figure out how to get the tumor out of Izzie's brain.
Meredith: Why are you smiling?
Derek: Because I figured out how to do it. Once Izzie's in the clear, we're gonna go to the Bahamas and have our wedding on the beach. The wedding on the beach club. You can actually have drinks during ceremony.
