What if you can't trust your own mind or memories? What if you don't have the resources you need to stay alive? What if you are under the control of people who are not in their right mind and they make poor decisions that put you at risk? Each of the characters respond to this situation wildly differently, and deciding who is right and who is wrong is not straightforward. 

Drugs? Mental illness? Alzheimer's? Caregiver neglect? Lack of resources? Somehow this episode about aliens is relevant to all of these things, and therefore one of the most relatable stories ever set to film. One trip to IMDB later we are pretty sure this was intentional. Yet again, this show had the best team imaginable and they created magic.
