[Tim walks with purpose like he's supposed to be there. It's worked for him the majority of the time he's been in the Up. And yes; as soon as they're in Roy's room Tim does a walk of the perimeter and checks for bugs himself.]

I don't understand what the disparity in conditions does for this experiment? I mean these differences exist between the rich and the poor already in our world but to kidnap people purposefully to do this to them? I just don't understand what they're achieving with this?

Why add the mandatory sex? How are the people not only okay with this but seem to actively enjoy enforcing it on those they kidnap?
