I'm really hoping that if we have to suffer through a wedding Pince/Blair, I can just have a a few little things. 1) Chuck delivers another ulitamtum echoing the Empire State Building Emotional abuse.
Chuck: "Blair, if you marry the Prince, we're done forever."
Blair: {roll eyes} "I think that is what me marrying someone else means."
2) Dan declaring that he wishes they had a chance to find out what could have been and telling Blair he'll be her not friend no matter what, but if she wants to back out he'll have an escape route ready.
3) When offered a chance to speak now or forever hold their peace. Blair speaks up and says "I don't".
4) Blair goes out a side exit to a limo Dan has waiting for the escape Blair says quick goodbyes to Serena, Nate, Dorata, her Mom. Slaps Chuck down again that not marrying the Prince doesn't mean she wants him. Then from inside the limo, paparazzi running towards the car, Blair barks "Humphrey in the car!" Dan jumps in, reaction shots from everyone realizing Blair and Dan are Blair AND Dan, door slams shut. Season end.
:D
