The "mother and father," in this episode,
are the main reason people need to pass numerous tests to be even qualified to have children. This entire family are all monsters, mother, father and son. I'm not sure why this episode was written. If it's a true story, which is unfortunately possible, then maybe it's a warning to what horrors parents can create. If it's not a true story, then the writers have serious mental and emotional problems. Ugh. Sick, sick, sick.
