While that is purely speculation on my part, I have had that feeling since the first time I played that part of the game, the moment I learned that the cow-girl costume you can buy is not the one you give to Auntie Diane, I really felt it strongly. It could be mom, and it could be just a change of plans too (like he decided not to make you buy it for the quest), but the evidence is strong.Keep on shinnin' my man! (Remember, we dont wanna be suued)
I believe someone had mentioned judith is supposed to help out with the milk and aunt thing??
I am usually good about reading the clues, but things change in a project like this, and many good writers try to mislead, so I have been wrong before. XD
