“Back and Back and Back to The Future” is episode five (maybe) of season one of Farscape.
Moya comes across a disintegrating starship and, after D’Argo discovers that the crew are related to the Luxans (his people) and are long-standing allies, a pod from the spaceship is taken on board.
Crichton touches something in the recovered pod and starts experiencing visions of some type, after a green energy field enters him.
The rescued crew members start acting a bit suspiciously, not that D’Argo can see it.
It seems that Crichton is getting glimpses of the future.
Can’t say the fight scene was that convincing. The temporal flashes that Crichton keeps seeing also cause things to get a bit confusing.
This is sometimes listed as episode three, not five.
