This is a result of a conversation I had with myself. During the Look before you Sleep episode AJ get's all frou-frou. Anywho, She got dressed so fast (like what 2 secs?) I started to wonder if she secretly liked to dress-up. Remember during the Cutie Chronicles episode she wanted to be a refined young filly, so I really don't think I am off here. also AJ looks good in a dress.
