That sort of thing, Crystal knew about. She might not know the exact details of 'Ro's experience, or understand everything the girl was saying, but the basic idea was obvious. The man was a scientist, but not a good one like Susan Storm who helped people, he was a bad one who hurt people. Crystal knew all about experiments and what they could do; her people were the products of experimentation, and later on some of her own people had performed horrible experiments of their own.
"You think he will hurt other people? Do more experiments?" Upset at the idea, a faint green glow appeared around her hands and the ground beneath them shook. It was only a slight tremor compared to what Crystal was capable of, and the affected area extended maybe twenty feet around them, but the movement was still able to be felt by anyone standing within that area.
