I’m still pissed off that he and Lily ended up together. He has never had good intentions in the whole series, and it pisses me off that he got the happy ending that he wanted but not deserved. He gave Lily fake cancer, attempted to break Rufus and Lily up and tried to destroy her life in S6 yet he still ended up with Lily in the end. He never really added anything to the show except drama and he just made me annoyed because every scene he was in he was doing something against Lily, but in the end he’s doing everything “for Lily."
I actually really liked Ivy and felt quite sorry for her, I mean, she was paid to do this job and eventually became attached to the Van Der Woodsen’s due to her previous family background. Also in the last season with William, I felt so bad!
