Never mind the fact that saying yes to Michael equals death to half the world anyway. You wanna save the people you care about? Right. What's gonna happen when Mom, Jules, Mel, me, Ruby, and everyone else is caught up in the half that goes kablooey?
You can claim that you'll just deal out a back-up plan for everyone when you mark your terms with Michael, but in the end he's gonna be the one that's in charge. You're his meatsuit, Dean. The second he's got his hands on your reigns, he doesn't have to do a damn thing for you or anyone else in the world.
You were ten seconds away from ending half the world, potentially including the people you care about and all of everyone who came through that seal, without giving any of us a shot at finding another way. And yet I'm the one who doesn't understand, I'm the one who's screwed up because I haven't thought up a plan yet that makes you happy.
Instead of trying to ship yourself off to Michael, why don't you try to help me think of something? I don't even think I've seen you pick up a single book on the apocalypse since you found out we were having one.
