Put simply, there is no hiding place.

Non-mutants have no defenses of their own.

And mutants may or may not have defenses, based on their abilities.

But we're not about hiding.

I had ... Kwannon ... inside my head, reading my thoughts. I was sending thoughts at her specifically, I wasn't trying to hide. I was trying to keep her off-balance, and it worked. To some extent.

You have to find out what works, when you can't hide.
