Season 4, Episode 18 is gearing up to be a juicy one — and not just because Blair (Leighton Meester) faces some tough choices in her relationships. Raina (Tika Sumpter) asks Nate (Chace Crawford), "Have you told Chuck about us?" Between that, the Dan and Blair kiss, and the revelation that Bart Bass may have been responsible for Tika's mother's death, we're a little afraid of what the future holds for Chuck — and the UES.
