Is there not a difference between doing a 'favor' for someone and 'obeying' them?
As I understand your direction on this, you are saying that if I pray to Mary and ask her to ask Jesus to answer my prayer, He must do so because He has to obey His mother. Is this what you mean?
If this IS what you are saying then are you not giving Mary the same all-knowing, omniscient power as Almighty God? By this I mean, if a million people are all praying to Mary at the same time for their own needs, she can hear them all and intercede for them all separately?
Sorry...I don't see it.

Nope. If I ask Mother Mary for an Evil thing, why would Our Lord have any interest in helping even assuming His Mother asked?
