The look that Cassie shot towards Teddy was one of grateful surprise. He was proving an unlikely ally lately. When she turned her gaze on Billy she was uncertain and Cassie frowned thoughtfully for a long moment before suggesting, "It's possible, isn't it?" Holding up a hand to quell any protest she continued, pacing again as she went on, "I mean. You trusted Magneto when you got here. Both of you. It's not such a stretch to think he could've charmed Tommy, and Tommy's...well, he really wants a family, doesn't he? Maybe Magneto sort of gave him that. I don't Tommy would do anything bad intentionally-" well, okay, that was totally a lie. They'd busted the guy out of Juvie and he'd always sort of been a troublemaker, but it wasn't like she had to point that fact out to his brother- "But if he thought he was doing right. Well. I just think it's possible, is all."
