It's not something you don't already know. It's just that I saw a comment in some forum. I posted it here, to share it.
Tell me what you think.

"After looking at the spoiler pics on other sites it looks as if chuck is trying to put together a best man speech outside the palace before the reception. Blair comes along and encourages him, says he’ll do great. He gives the speech, he successfully gets the thumbs up from his dad, and then rewards Blair with a dance for believing in him while he was struggling. Hmm…hopefully a kiss too…but there haven’t been any spoiler pics for that."


So, do you think it is possible? Give your own speculations ;)
