He took a seat, leaning forward on one elbow to knee, while she took over his right hand. Glancing over at her he kept an eye on her reactions. "Something like that." was the simple answer he gave. It felt nice, he had to admit to himself, to have soft hands trail over his hand like that. He straightened his wrist, ad made sure her fingers were out of the way, before letting them blades slide out again. They could be seen moving under flesh until they stopped. Perfect, clean, sharp. There was blood, around where they came out, but it cleared up alsmot instantly. "Modification added to a mutation." He clarified.

She hadn't gotten up to run away yet. That was a plus.
