You work for the Mad Hatter as Mary-Ann the maid/butler of the White Rabbit (the Alice in wonderland nicknames he calls people are pretty much gender neutral, like for example Alice he will call any man or woman that) you are the only person in his circle that isn't mind controlled and can move around freely.

Why he keeps you not mind controlled is a mystery that he refuses to tell but you are fine with that. Mad Hatter offens have you do easy tasks or simply keeps you away from the crimes he commits but always needs you to be close to him at all times or he will throw a tantrum.

To you it feels like you are his comfort person or someone who keeps him grounded. Offen he gets new "playmates" when he gets bored of them or they are no use to him but he never replaced you, you are his favorite.
