If they kill Xander off, I don’t see Victor being the one to do it since Xander already told Victor that he would "kill" for him — but I’ve certainly been wrong before. Maybe Victor will just give Xander the job of being the hit man for Clyde, but Stefano will have other plans for Clyde because of Kate. I don’t think Stefano has any idea that Clyde was involved with taking out E.J., even though Stefano’s own man shot him. Either way, I think Xander will die — not sure about Serena’s exit though.
