Tells him she doesn't know

Ashley thought about how to imply that she didn't know what her power was without making a statement that would activate it. "What if," she said at last, "I didn't?"

"Well, then, we'd still accept you, and when your ability appeared, you'd be among friends who could help you understand it." She breathed a sigh of relief, thinking she had managed to dodge the question. "Is that what's going on?" he asked, "Are you unaware of what your power is?"

Shit. That wasn't a question that could be answered easily by a question, and if she kept dodging it without saying anything, he might get suspicious. She swallowed. Would one small lie really be that bad, if it meant she could live normally with other mutants after this? Or should she keep trying to trick him with ordinary methods? Surely she couldn't come clean, not now.
