Another... patient? Confusion slid across the boy's face obviously. It was possible that there were people with the skills needed for that here, yes, but the need for it escaped him.

The last Mikado knew some people were getting sick, but to call it something like that just seemed strange.

The man introduced himself in turn before Mikado could ask, and the boy nodded politely. Castiel. Another strange name. More like Tolten than Lily or Snow, but it was still something he had never heard before. Rather than repeat it to sound it out, Mikado questioned Castiel further. "You said... infected. What do you mean by that?"
