Very similar to There’s No Place Like Springfield from G.I. Joe where Shipwreck is convinced he has a wife and daughter and left the Joes because he was responsible for the death of Lady Jaye. The episode was particularly poignant to kids at the time because they utilized shipwreck, the irresponsible, reckless womanizer, gave him a family and then ripped them away from him in heartbreaking fashion. To make it worse the wife character was based on a character from an earlier episode that he had fallen in love with but did not end up with. When you’re a kid, that was pretty heavy stuff. It was mind blowing to kids at the time and is almost beat for beat the same major plot points of this ST:TNG episode that came out years later. The Joe episode was inspired by another older source if I recall correctly. Two good episodes of two good (and entirely different) shows. The two-part episode Worlds Without End was also very good, and showed the G.I. Joe team confronting an alternate universe where they were all dead (except for a few MIA Joes that they never specified) and had lost the war against Cobra. Some of them came across the bodies at of their own counterparts at one point, killed in a Cobra experiment. Those three Joe’s ended up staying in the alternate universe to try and turn the tide against Cobra instead of going home. Good stuff when you’re a kid.
