I'm just gonna go ahead and say that I've just been messing with your head and I don't know anything about the account at all.

Perhaps the entire Staff passes around Quina and they each have their way with him/her. I wouldn't put it past them.

Also, I find it really amusing that people make guesses on who Quina is based on the nicknames Quina chooses for different people. As though NO ONE ELSE in the universe can use a particular nickname for someone.
