Beautifully made episode and somewhat unsettling, it does not only introduces the main idea, but also demonstrates possible reaction by ignorant, angry and destructive reaction both average "son" and "wife" demonstrated when faced with "possibility", instead of seeking to understand they became upset/angry with almost no hope of hearing the possible facts and explanations, literary closing their mind to everything the main characters tried to explain, which resulted in actions without thinking. I am not surprised. The story and plot flow are probably written to make it interesting to "General Public" . It is also somewhat illogical when a "wife" character talks about forgiveness in the end, but cold-bloodlessly watching that mad scientist get get killed, just groovy. The author also for some reason eliminates all the scientists and portrays them as bad guys, that is not only illogical, but sick, but makes a great "story" I guess.
