"It doesn't matter," he smiles. "If that's what you have, that's what you have." He pauses. Should he press the issue of past bad choices and the circumstances they were made in? Because they clearly really need to talk about that, and since the seed (he's calling it the seed because it wanted to be called Legion and he won't dignify it) hadn't given him a straight answer, he's pretty sure that there was one to be given.
But it isn't his business unless and until it interferes in some way he can call them on. So he just goes on, "Whatever it is you have, or that you use, I'd like you to use that to attack me, please." He nods. "Please convince yourself that I'm going to hurt him, and come at me as hard as you can in that way. Without moving your feet."
