Ignore the obediance stat... it's meaningless. For the hell of it I played a Valerie max obediance run, no cheating (by either of us), always went to lunch with her when available, always went home with her. I mean MAX couple shit with like -8 or so corruption. She still fucks fat boy and Darius (and even the captain) on the boat. Absolutely NO variation in the way it plays out. If she goes on that trip she WILL cheat. Up until that scene cheating was avaoidable. Technically it still is if you avoid having her sent on the boat trip.
