Dan and Blair I read a spoiler somewhere...have آپ read it 2?
It said that even though Blair admits she has feelings for Dan, she finds out Serena wants him back, so she leaves him. Chuck and Blair spend one night together for the last time. Then Blair gets engaged with the prince, Chuck in arrested for Raina's death in a fire (caused accidentally by her father), and his only alibi is that he was with Blair that night. But he doesn't want to ruin her engagement with prince Louis, so he doesn't say anything. I imagine that Blair comes to his rescue. what do you think?
