Well, the Kristen plot seems to get all the airtime. Are we ever gonna solve Charlie's murder lol? And Nicole could have been a normal human being and just called Eric back. Or went to visit him. Or anything other than what she did. Clearly the show has no idea what to do with Xander without Sarah. Same with Ben.
I would see a purpose for Xander and Chanel if the storyline was still going on. What exactly was the point to them getting married and trying to scam Paulina if they've already been moved into their own separate storylines?
