Anyone who's spent time around enough PhD's knows that high intelligence does not imply high wisdom. Why would we expect Xykon to be any different?

Getting back to the original topic: "Xykon somehow knew RC intended to swap out his phylactery for a fake, and masterminded a plan to give RC a fake instead of feeding him to acid-breathing sharks" may be the crackiest theory I've heard this year, and I spend some of my time on Twitter. (^_~)

But personally, I don't think that's a bad thing. Thanks to M*A*S*H, I developed a firm belief that when reality goes mad, the best defense is to use humor to out-crazy reality.
