Regarding the trip to the restroom, is is possible that one of those larger rigs is a solution in disguise? He steps behind a tree, opens the back of the camera, clicks the leak proof shutter on the "time" setting, does his thing, closes the shutter and walks away. Perhaps he's walking alone because one of his rigs sloshes. Of course, he has a lab assistant to empty it and wash it out.
