So I was just wondering. Does anyone know what happens in 2x24? Because I heard Nate and Blair breaks up but I'm not sure if they do au why!?

Well, Ausiello gave a spoiler saying that episode 2x24 will make CB mashabiki very happy, so that could mean that that's when NB break up. But also, there is a spoiler saying how Chuck will be furios at Blair for attending prom with Nate - which makes no sense to me 'cause it's completely normal if she decides to go with her boyfriend, and Chuck shouldn't be so mad. So it leaves me to thinking they could break up in 2x23 instead.
Also, the description for episode 2x24 says that Blair and Nate's plans for prom doesn't go as they thought, so yeah...could also mean that.
But idk, there's no excat spoiler saying when they will break up. All we know is that episodes 2x24 and 25 will be good for CB fans.

I think they will break up because Blair is going to figure out whoe she truely loves (not that she didnt already know). But spoilers say Chuck is helping her win prom queen.. this could have something to do with it. :D

I think Blair tells Nate "I don't upendo you" au something and then runs to Chuck
