S1·E15 Durka Returns

When a Starburst goes badly wrong, Moya collides with a Nebari ship. On board is Durka, Rygel's former torturer, who has been mind cleansed and now serves the Nebari. Chiana, an attractive young rebel faces the same fate. Rygel takes it upon himself to take revenge on Durka and ends up undoing the cleansing and restoring him to his former, tyrannic incarnation.
