Picking at the ends of his sandwich, John considered the options. He was hardly comfortably with telepaths just doing what they liked, and there were more than a few who were powerful enough to get in without any trouble, Xavier had, and Pyro wouldn't have known if the cripple hadn't brought it up.
When it came down to it, it was better the devil you knew, right? And as much as Pyro doubted anyone really knew Emma Frost, she was probably the only telepath he'd even sit in company with at that point.
"So you can do this in diamond form too?" He knew that Emma in diamond was cut off from her telepathy, which meant there'd be no way she could enter his mind at all. Which was probably an easy way out, but right then, John would be more comfortable with it.
