Youko has...human fingernails, right? [He's never actually spoken to her but apparently she's some kind of shapeshifting fox? Claws seem like a possibility.] If so, I believe we may have already found the person she struggled with, and subsequently scratched.

[Zelos's hairs go unnoticed for the moment, as Faize has finally turned his attention to inside-on-the-outside organpalooza instead. So uh...if he (gently) digs around in there, is he going to find anything other than organs? Or anything weird on/about the organs?] Zelos's crystal is unaccounted for, as well, though the plate is still here.
