Irahl is sure he's got this. Even as Vincent succeeds at pawing him over by the face because the only thing holding him up is his bad shoulder, he is confident that this is all part of the plan. Vincent spins the room in the other direction until Irahl's back hits the mattress, and he is sure that his drunk friend is playing right into something he has accounted for.

He hasn't. He just feels more in-control because he can't be knocked over any further than he already is. Yes, he can be capable of controlling a fight from the ground, but unbeknownst to him, this is presently not one of those cases.

At the moment, he is undaunted by being crowded and pinned down while extremely shirtless and half-injured. Still grinning, he locks his good arm with one of the limbs pinning him down... which does gain control of it, but not in a way that actually helps or hinders anyone. And his bad arm is the one he that starts trying to hit Vincent with.

Take that.
