Season 1, Episode 16:
A Human ReactionThrough sheer happenstance, Moya discovers a wormhole and Crichton sees Earth at the other end. He flies down the wormhole in his module and crashes in Australia, but the homecoming is less than welcoming. The government is suspicious and wants to know everything about Crichton's time on Moya, and even Jack, his own father, seems distant. Things get worse when Aeryn, D'Argo and Rygel arrive in a transport pod and are locked in quarantine, something Aeryn says even the Peacekeepers would never do.Things reach boiling point when Rygel is killed for the purposes of autopsy and D'Argo disappears entirely. Jack helps John to escape the government lockdown and he reunites with Aeryn, who escaped quarantine when the government came to take her away. They hide out in an old apartment of Jack's, and that night they sleep together. Next morning, Crichton begins to realise that everyone and everything he's seen since coming through the wormhole is based on something from his own memory, including things that couldn't possibly exist anymore: he tests this hypothesis by trying to visit a place he's never been before (the ladies room of a local pool hall), only to meet an energy barrier.It is revealed that everything was a giant simulation, a test built by aliens known as Ancients, who are trying to find a world where they can settle down. Aeryn, D'Argo and Rygel really did come through the wormhole, but the latter two were spirited away from the simulation when required and treated well in the meantime. "Jack" is really one of the Ancients, who wanted to provoke a human reaction from Crichton to determine how the people of Earth would react to the Ancients arrival. Humanity failed the test, being too destructive and suspicious, so the Ancients must continue searching and examining the memories of other races they encounter. Crichton and "Jack" wish each other good luck at finding their home, and the crew of Moya return to their ship.So, that was the typical Yank the Dog's Chain "fake return home" episode that every Trapped in Another World series does eventually, and nothing in it will have any future relevance after the Reset Button got pressed. OK?
