Are Miss Waldorf's actions justified? Serena was going on about how "this is one time too many" that S had to back down for B. However when you think about it Serena did have sex with Blair's boyfriend. Tsk tsk.
On the other hand I guess Serena was a good friend to Blair other than that unpleasantness. Serena was there through the little (retching) problem.
What's your opinion?
