I doubt it's about the scanners. Jeremie had to use them on himself after XANA Awakens, in New Frontier, and in Ghost Channel. And he still got possessed in Mister Puck.X.A.N.A wrote:I also wonder about something, how was William possessed by XANA? I thought all who go through scanners couldn't be overtaken by the ghosts? Unless because it was XANA 'himself' as a ghost, it made that fact null and void?
It seems to be the more one fights against XANA, the greater the immunity to him. And on the flipside, the more one fights with XANA, the more susceptible a person becomes to possession. I heard that was one of the reasons the gang didn't want William to go into Lyoko in the episode. Don't chance letting XANA get his next-to-strongest warrior again.
