He makes sure not to make it obvious that he's keeping an eye on where the two go, instead pretending to be just edgy around the guard. "Can't I wander? Feelers last longer than a few minutes, don't they? You guys keep bragging about how great your culture is, but I haven't seen any of it yet that hasn't given me the creeps."

He keeps several steps ahead of the guard's stride, which puts him at a rather fast walk. "What's 'this area', by the way? How big is it? Is it just within eyesight? Why can't I leave? What if I have to go back to the ship for my Med Kit?"

Questions, hopefully persistent and many enough to dull the guard's memory of Howard's run-in with the little girl. Not to mention that he really does want to know why they're so strict about what the visitors can see. What better way than to stick them in a movie where they have to spend two hours in seats?
