They would have to get a sample, it was possible he had used it on Laura and she needed to know if they were going to help her. They also needed to know how to counteract something like that. Rising she brushed down her coat before going to get his chair for him. Wheeling it next to the bed she set the brakes. "If he still has mutants under his control, we have to help them."
