User blog comment:M Bierhoff/Why is Avagraine in leauge with Morgana?/@comment-4560619-20111029022908

Maybe he knows Arthur has the support of the knights and the people. He doesn't have the power to take the throne himself, so he's throwing in with Morgana. But I'm with you... I'll bet he thinks he can fool Morgana by helping her now, and then get rid of her later.

I'm with the Agravaine-is-a-dead-duck people.
