further angers him when he tries his moves on Blair Waldorf
Yay, Chuck fighting for Blair! Super excited. Serena's new love intrest should be intresting as long as he's not another Aaron Rose...

Still tring to figure out how all this can mix with Nair... At first I thought the idea of a Blair/ Nate fake relationship for the sake of Nate's granfather wasn't too plausible, but now I'm reconsidering the idea. Since I still do think that at the end we'll have Chair (the new set pictures showing C and B together: they must be planning something against Gabriel!) I don't see how there could be enough time for Carter/Blair Nate/Blair Chuck/Blair.
I wonder what's going to happen with Dan too.

I think No Doubt will perform for their Prom night. And I really think the picture of Blair and Chuck together is for Serena. Since Serena will have trouble with this new guy. wonder what will happen to Derena? and whats in store for Dan, georgina and Everyone

if everyone could see the old Spoiler youtube video from a guy said to be Gabriel, he said something about 'HIM... he is jealous of someone who is close to serena. and he ask serena to go for a vacation with him. OMG! not it all make sense

The love child recap makes no sense. There's no way in hell he's the same age as Serena and Dan...no possible way...literally no way.
