It will probably be Dan kissing Blair. She will slap him. The poor guy just doesn't get it. This whole him fawning over for Blair thing after she repeatedly shuts him down is getting old. It makes no sense. It seems to me as though Dan, after being crushed by Serena YET AGAIN, is trying to make Blair into his rebound of sorts. But it's coming off really awkward and uncomfortable for me personally.
Id also like to add that the Blair/Louis wedding makes me sick. They throw this guy into the scene last season and we're just supposed to accept this guy as her child's father and now her husband? NO ONE EVEN LIKES HIM. Do the writers listen to anyone??
