Peter can't help but chuckle a bit at her reaction. Okay, so maybe he gets a kick out of blowing people's minds with his freaky powers. Who wouldn't?

He flexes his fingers a bit and gives her a shrug. "I heal really fast, this was almost completely healed up by the next day. I can do some other weird stuff too, but I think out of all my powers, this one's my favorite." He can do all the stupid stunts and shit he wants, break his arms like a moron, and be ready to go again the next day.
