“Thanks for Sharing” is episode seven of season three of Farscape.
In the previous episode, “Eat Me”, Crichton, D’Argo and Chiana were all doubled by a mad scientist. D’Argo’s and Chiana’s doubles (or were they the originals?) both died, but Crichton’s didn’t, and no-one knows which is which.
Talyn, meanwhile, is dying, and Crais is ill. D’Argo, Chiana and Rygel go down to a nearby planet and, as usual, get involved in trouble.
It turns out that Talyn was attacked by the Peacekeepers, who want him back – and their commander is Aeryn’s mother. This will not be a terribly happy reunion.
