Mordred chuckles at the misunderstanding, and out of frustration. Mostly frustration. 

"No." His voice flattens, obviously trying to be calm. But he has a certain manic angst going on. But he looked her right in the eyes and layed it out. "Not at all, I just don't care if it happens to me. I've lost what little life I've gotten away with having. And now I'm getting locked up in a school designed to make me another normal, brainwashed member of society. I'm saying that I have no reason to object to it. So, if she wants to kill me, tell her I don't mind." 

And with that, he throws his arms out to the sides, inviting her attack. Every ounce of body languge and emotion said that it was all true; that he just didn't care anymore.
