John saw one of the other heroes enter the room as he paced across the training mats. He figured they'd be going over introductions soon enough and he was deciding what he wanted to hide from the group. He figured that until he felt they could be trusted, he'd go by TK. He didn't need any of these heroes going rogue and hunting down his family. He also decided that when it came time to use his powers, he'd pretend that his hands were needed when in actuality, John's hands only needed to be extended when he was using his power to lift much larger items.
