as far as pain and madara/tobi - if this is true - is concerned, it could just be that Pain respect him since he is older. why must we alway conjecture something dramatic? (feel free to answer, but dont be serious). Remember that every member is in Akatsuki for something different, so its more like mutual respect. but they can still take advantage of each other of course. being submissive can just be part of a plan, duh.
