Goof: When Crichton is being interrogated by Scorpius, Scorpius comments on the vast array of races Crichton has seen. However, one of the races shown was not directly seen by Crichton, but by Rygel – the alien Rygel conversed with in the first episode of Farscape on the commerce planet.
Nitpick: Crichton flies Aeryn's Prowler to the Gammak Base- wouldn't the vehicle have some sort of IFF beacon telling the Peacekeepers whose ship it was? It certainly wouldn't be registered to Larraq, and with Crais in the neighborhood, a plane squawking Officer Aeryn's Sun's ID would definitely be noticed. Chiana must have some pretty impressive hacking skills if she was able to alter it to remain suitably anonymous, an ability that was never mentioned.
It is revealed in this episode that the Ancients put the information of how to create wormholes in Crichton's subconscious mind, believing if he couldn't discover it on his own, he couldn't handle it wisely. Crichton's unconscious knowledge was supposed to guide him along the correct path to its discovery. Unfortunately, it seems to have led him directly into the clutches of Scorpius, whose Gammak Base is devoted to the creation of wormhole weapons. This plotline will be central to the remainder of the series.
This episode is the first appearance of Scorpius, the Peacekeeper Scarran-halfbreed. He will have an important and central role for the remainder of the show.
This episode marks the appearance of Stark, a Banik slave. Like Scorpius, he too will play a major role through the remainder of the series.
Stark: (when John is thrown into his prison cell) This is my side! That's your side. You stay on your side. My side, your side! My side, your side! My side, your side!
Crais: I order you to give me Crichton!
Scorpius: Your adherence to orders is often selective...
Gilina: I've programed a blind spot into the targeting sensors. Keep your Prowler on this trajectory and they won't even see it.
Chiana: Well, how will I know if it works?
Gilina: You won't get blasted out of the sky.
Zhaan: (referring to D'Argo's suggestion that they use Moya to stabilize Aeryn) Why didn't you want me to tell Aeryn it was your idea?
D'Argo: Earlier on Aeryn told me she wanted to die alone. As a warrior I should respect her wishes and not interfere.
Zhaan: You did a good thing. You may have saved her life. Despite her words she really didn't want to die.
D'Argo: I do not even believe she wants to die alone.
Crais: You are dead, Crichton. But you have one choice - do you wish to save the lives of your shipmates on Moya?
Crichton: What are you talking about?
Crais: Why do you think I'm here? I've recaptured the Leviathan. The fugitives are back in my custody. However, whether I deliver them alive or dead is up to me.
Crichton: How do I keep them alive?
Scorpius: Stop resisting the Aurora Chair. Allow us to probe freely...for any information we wish.
Crichton: That's not a very good option.
Crais: You are not in a very good position.
Crichton: (flashback) You're teaching me how to-
Jack: No. You cannot access this data consciously. You won't remember this part of our encounter. We will not give you wormhole technology.
Crichton: Why not?
Jack: If you're not smart enough to discover it on your own, you're not smart enough to handle it wisely.
Stark: (in the Aurora Chair) Again, Scorpy! Frell me again!
Aeryn: I'm not going to die?
D'Argo: As you once said to me, you will die, but not today.
Rygel: Oh! I, I came to see how you were doing.
Aeryn: You came to see if I was dead so you could start going through my possessions.
Rygel: Ugh! I resent your unfounded accusation! Furthermore, you have no possessions worth taking!
Aeryn: How inconsiderate.
Javio: (about Chiana) What did you pay for her?
Crichton: You don't want to know.
Javio: Does she give good...value?
Crichton: She has her moments.
Crichton: What the hell are you doing? You acting like a trollop was not part of the plan.
Chiana: They bought it, didn't they?
Crichton: You're drawing a lot of attention.
Chiana: The more they look at me, the less they look at you.
Crichton: Do you think that before they elect you centerfold of the year, we can get on with the business of saving Aeryn?
Chiana: You sure you don't want me to fly this thing?
Crichton: You know how?
Chiana: Yeah, you?

Scorpius was originally designed as a fully animatronic puppet, in the form of an insect-like creature.
In the original ideas for the series, creator Rockne O'Bannon had written Scorpius as a regular for the show, introduced in one of the first couple of episodes.
In the original script, Scorpius and Crichton had more conversation following Crichton's attempt to provoke Scorpy the first time he's put in the chair. It reveals Scorpius is half Sebacean, half Scarran. His mother was part of Scarran breeding experiments when they invaded his home, the Motak Four colony. It's obvious why the next bit of dialogue was removed, as Scorpius reveals that he killed his father, and his entire race. He made Scarrans extinct with a deadly virus. This information preceded the line "I long ago learned the advantages of patience". Of course, the Scarrans are not extinct and do appear in season 2.
This episode's title comes from author Dick Francis' first thriller. He wrote crime novels set in horse racing circles.
Crichton: It's deja vu all over again.
A paraphrase of one of baseball great Yogi Berra's famous yogi-isms, "It's like deja-vu, all over again."
Crichton: You should see my Immelmann.
Immelmann is an aerial aerobatic maneuver, 1/2 looping up followed by half a roll.
Crichton: For the ninth time, Nosferatu, I'm not a spy!
Nosferatu is a 1922 German silent movie based on the story of Bram Stoker's Dracula. In this film the Vampire Dracula was renamed Nosferatu because the director F.W. Murnau was unable to obtain the rights to Stoker's story directly.
Crichton: Fetch the comfy chair.
Crichton: Danger! Danger, Will Robinson!
After Crichton is being tortured in the chair he says "Danger, Danger, Will Robinson! Beware of the chair!" This is in reference to the classic television show Lost in Space.
