Whose behavior was the most appalling?

• Lily: she's forcing yet another family on her poor kids, one of whom was recently suicidal!

• Rufus: he's so wrapped up in his and Lily's lovechild that he's forgetting about his own kids at home.

• Nate: blowing off Chuck's brunch for old-school candies with Vanessa? Pretty lame.

• The Humphrey/Van der Woodsen kid's adoptive parents! How sneaky of them to lie like that.

• Chuck: he's let Blair down one too many times.
