What does he have to lose from trying? He hadn't really thought about it from that angle, not much, but his mind quickly supplies a list of worst-case scenarios.

"What if...the doctors don't understand what's going on?" He starts to pace. "Which they won't, because we can't exactly explain what we saw without...what happened to you. So we're gonna end up giving them only part of the story, one way or another, so they might wind up with the wrong diagnosis, so they might wind up giving me the wrong treatment, which could be, y'know, bad."

He doesn't want anyone else messing around in his head. Never again.
