forgot to say that if Stain gives the person the wound and can't lick it, he can lick his blade. (Yes i know all this is gross)

I'm really sorry to the people who are grossed out by this, i know all this blood licking talk is super gross.... :( i'm super sorry again to anyone who doesn't like this type of stuff.

What if
The character that he's fighting doesn't have blood-

then idk.
