an android rape scene could be intriguing psychologically...in terms of them viewing David as a non-entity, a nothing, a servant. Using him for sexual pleasure would be like using a towel to dry off with. It would be highly intriguing, even more so if David was the one doing the raping....of course, rape is a horrible horrible thing but it's the philosophy behind the creator misusing its creation, or vice versa. There are so many implications.
