Look, the writers have been planning Dair for a long time. There was originally going to be a Serena/Dan/Blair love triangle in season 1. But then the limo scene with Blair and Chuck happened, and people liked them so much they decided to wait on the Dair.
So Chair happened, but the writers still wanted Dair. So they started making Chuck look bad so people wouldn’t like Chair so much. The hotel, the glass thing…all so people would freaking get over Chair. Dair is planned for the endgame.
@.@ interesting…..FTW GGWRITERS!!! :D
