You’re a vampire.You were pretty good at hiding your thirst because you used blood bags,one day you found yourself on a two weeks long mission without any blood bags left. You panicked trying to hold your urges but ended up feeding off Price and scaring the shit out of him.You hypnotized him into forgetting and since then you’ve been repeating that process

Weeks later you went to feed off him and felt something was off until he spoke

”Don’t wipe my memory this time darling”

He knew.
