I said the last episode was a sign of improvement, but this episode was just a step in the entirely wrong direction. The Dan & Serena relationship has become so tired, and even though the whole "sharing a sibling" thing was scandalous, I just could not stand the story line.
The final scene really saved the entire episode what with Blair rejecting Chuck, and the whole Van Der Woodsen/Humphrey clan coming together, but the episode overall was quite a disappointment.
The characters are just not likable, at least not nearly as likable as how they were before. Any charm this show had when it started is now gone. The story lines are contrived, and it's just almost unbearable sometimes. I'm only sticking around for the return of Georgina but if this show doesn't pick up by then, I'm done with it.
