100+ This. My wife only reads the Books. I WANT TO DISCUSS THIS WITH HER SO MUCH.
It's not so much that it was a secret, as that the idea that he'd misread the Xykon plot completely, rather than just choosing to focus on his own personal plot (as the sub-plot relating to him), was what I missed.
I figured he knew Elan wasn't really the leader (which is sort of true), but not that he thought he could de-rail the plot by killing Roy thus forcing Elan into the narrative role of leader.
What I like is that, if he does manage to kill Roy, he's effectively *right*. Xykon is Roy's quest. If he dies, Elan and Haley would become the core long-term protagonists, and the main plot would revolve around their quest to get revenge for Roy, Elan's mentor, on Elan's father. Obviously, he's not going to kill Roy again (unless there's hidden value in DStP II: Another Turn of the Revolving Door), but it's not like he's completely misread it, he just thinks he can manipulate the narrative (when that power belongs only to the Giant).
I love this storyline so much.
