"I'm a mutant," she answered shortly, but that wasn't where she finished. "I am a mutant clone of a someone who has the ability to regenerate. He has claws like I do, although he has three in his hands where I have two each hand and one in each foot." There was nothing to hide here, really. If he tried to use her, he'd find it wasn't as easy as planned. She had no reason to lie about anything, and he'd 'saved her life' more than once tonight.
She dropped her clothes to catch the shirt. Slipping it on was easy, even if she had to let go of the towel to do it. It slipped off, pooling at her feet, as the shirt slid into place. She wasn't exactly shy about her body, but she didn't know how this man felt. It dwarfed her, hanging loosely off her body. The neck slid off her shoulder as she reached down to collect her clothes and his towel.
"Thank you for the shirt," she said offering him back his towel.
