Alright I give up.
There are too many references which state that Mary is the man's Mom so I can't believe anymore that she is his Maid, it becomes too obvious that she is his Mom and that he has an Oedipus complex.
I wish you said from the begining that this game is about Oedipus complex as I am not into this fetish and now I feel awkward to play a game which is not meant for me.
