During Crichton's torture scene, Natira remarks how rare blue eyes are.
Despite this, Aeryn, John, Rygel, Scorpius, Zhaan, D'Argo, Jothee and Braca (all the recurring characters at this point on the show, except Crais and Pilot) have blue eyes.
Chiana's eyes are black, but actress Gigi Edgley's are blue.
This is the first episode in which Crais and Pilot, both of whom are played by Lani John Tupu, have an exchange of dialogue.
Crichton's Young Frankenstein (1974) reference. "It's kind of hard not to flinch here, Scorpy, with Frau Blücher tickling my prostate."
