I was writing simmilar stuff several pages ago, i have alot of ideas. No doubt Judy is mystical and its interesting to know what she really want to do. Judy told us that she graduated 4years ago.
So her age is about 25-26 as far as i understand US education system. may be i wrong - correct me then. So anyway she is not over 30, so is highly doubtable that she has grown daughter. More likely she has her own interest in this story. My little analisis:
In prologue we can see thoughts of Judy that she knows Mom already.
Its also was her who planted icest idea in MC head.
Also she said to MC that will wait his report about some stuff with family members.
For me its ovious that she is manipulator. She work in school already 4 years from her graduate from university. And i think it was her who gave The Book to Mom. What a pity book author is not Judy. Its Dr. I.C.Stor
P.S. May be its just i see what i want to see, but i hope that story really will be deep and full of twists =)
