In the locker room, Meredith and Derek have their own talk. She tells him that if he wants to break up with her, he needs to just do it, but he throws her a curveball when he instead tells her that he loves her and can't leave her. "But you're constantly leaving me. You walk away when you want, you come back when you want. Not everyone, not your friends, but you leave me. So I'm asking you, if you don't see a future for us, if you're not in this, please, please just end it because I can't. I'm in it. Put me out of my misery." I still maintain that he's the one who's been causing more misery by getting so upset that she doesn't react to emotional trauma in the way he wants her to react. Either way, I want to put an ice axe into the skull of this story, and have them go one way or the other and get on with it already. Meredith just shakes her head and says she can't, since she has to make sure Cristina gets married. "I really need to make sure she gets down that aisle." Defeated, he tells her, "Let's go. We're running late." You can't break up with her, but you can continue to make her feel guilty and on her toes about your feelings all the time. Boyfriend of the year, that one.

The church is filling up, and Derek and Burke are standing together. Burke asks if Derek is okay; Derek merely responds with some lame getaway-car jokes, as all best men are required to do. Burke tells him that if it's about his being Chief, it's okay. Derek quickly answers, "Richard didn't pick me to be Chief." Which, actually, we now know is a total lie, and I get what he means by saying that, but what he should have said is, "I'm not going to be chief." See, then he's not technically lying in church. Burke is surprised, since everyone assumed it would be Derek, but Derek maintains that he doesn't know who it will be. Burke then presses Derek about how he doesn't look good, and Derek finally sadly admits that he and Meredith might not make it, since he thinks he wants it more than she does. But he puts his happy face back on and tells him today is about Burke. Burke tells him he really is a good best man. Better than he is a boyfriend, for sure.
