“They’ve Got a Secret” is episode ten of season one of Farscape.
The crew is checking Moya for Peacekeeper technology, in order to deactivate and remove it, so that, should Crais come in range, he will not be able to use it against them.
D’Argo finds some and is trying to deactivate it, rather forcefully, when he gets expelled into space. Even though he was out there for half an hour, he manages to survive.
Moya, on the other hand, is less than brilliant – and Pilot isn’t doing too well either. Some of the DRDs start acting oddly too. A biomechanoid virus left behind by the Peacekeepers is affecting the ship. And D’Argo. Exactly the sort of Peacekeeper tech they wanted to remove.
D’Argo inadvertently reveals some of his past.
