He watched Rachel leave, and when she was gone turned his attention back to the healer. Khem. After blankly watching her cleaning up puddles of blood, his eyes suddenly widened. "No! Don't...don't touch it."

He had been very careful to not let on to The Masters that lycanthropy could be bloodbourne: they had tried their best to get him to infect others in as many ways as they could think up. A few had been infected by his blood, but he'd been aware of the transition before they were, especially with no full moon in space to force their bodies into that first transformation. He'd managed to find a way to kill them before their infection could be verified.

He still wasn't sure of all of this, but this one seemed genuinely kind and he didn't want to have to kill her.
