What plot twist most disappointed you?

[Rrmcklin]

What's clever about this is that there are multiple layers to that. Xykon isn't dumb, and he probably knows that the MitD is trying to save the Order, but what he wants to do most is to reassert his dominance on Redcloak. And there's no better way to do it than by taking the advice of the guy who is obviously covering for the good guys.

That's how I read it too. Xykon felt he had been bested by Redcloak in the Tsukiko affair, so he lashed out at the earliest opportunity in the pettiest way he could think of just to put Redcloak in his place.

Pretty sure we have word from the Author that that was exactly what was going on. I don't remember what thread, though.
