Oh, I know you're not a demon. Let me take a guess. You're an ancient hag from 1604 that's one of Lana's ancestors, and you spit some blood into a book and now think that because you can possess her body, you are powerful.

However, binding tattoos are breakable. And I'm pretty sure Lana won't mind a little pain from me in order to make sure you never come back to hurt her again.

So last chance, leave nicely, or I'll make sure it hurts.
