Throughout the episode, they undertake more subtle measures to try to convince him that, among these people he cannot trust, he is going mad. Such measures include switching his tent, leaving him confused about whether it has been there the whole time; and telling him to drink his glass of milk that he so fervently asked for despite his never having asked for a glass of milk. At the end, convinced that there "must" be something wrong with him, Buzz is shipped back stateside.
