I don't see how...and how would they have changed it? Would they have played a classical version of the theme song? Haha I never really thought about it. I mean it didn't take away from the emotion or anything like that. Did it make you uncomfortable? Was it because of how upbeat the theme song is? I feel like it makes sense, that they didn't change anything. It's kind of like...even though this tragedy happened, it's still Buffy. Even though the feel of the episode is entirely different than any other episode of the show, in my opinion, it would have felt odd if they had changed the credits.
