What happened on New Years on Gossip Girl?

i dont think anyone knows, but i think its that her and chuck uncle, jack bass did something together. because remember when shes telling serena she told chuck she loved him and then she said theres something else, but dan walks up? so yea... im so ready for the new episode to find out...!!

I copied and pasted my answer for a question concerning the same thing:

They didn't say, but I have a feeling Blair and Jack hooked up on New Years. Remember when Serena and Blair saw each other for the first time since Serena got back and Blair told her she had to tell her two things? Dan interrupted before Blair told Serena about the second thing, so Blair never got to say anything.

Plus, on next weeks' promo, Chuck says something to Jack along the lines of, "Blair would never touch you."

Jack and Blair did hookup. If you watch closely in episode 25 of season 2 (The Goodbye Gossip Girl), you ll see that Jonathan is showing Serena, Jenny, and Eric how he hacked Gossip Girl s e-mail. And there is a brief frame of the e-mails and one of them is from a Joel Custer that said Jack and Blair hooked up on New Year s Eve.

Jack Blair

I'm pretty sure that Jack and Blair hooked up. Which makes me very sad.

I was thinking the same thing!

Ah, uh check like a spoilers website, they might have a little clue to what happened.
