On a world where clones are created and harvested for spare body parts, Quinn is mistaken for a clone and captured, while the others inadvertently rescue his clone, whom Colin tries to teach the importance of family and sacrifice.
Tropes present in the episode:
- Clones Are People, Too: The core of the story. While Michael Mallory doesn't see the harm in what they're doing, Quinn's double does and refuses a transplant. In the end, Michael refers to the Mallory clone as his other son.
- Expendable Clone: On this world, clones are systematically harvested whenever the original human needs a transplant.
- Eye Scream: A lab accident costs Quinn's double the use of his eyes. Quinn and the Mallory clone are threatened with losing their eyes as a result. RJ also wears a covering over part of his face—suggesting one of his eyes (and possibly more) was harvested.
- He Who Fights Monsters: RJ, a renegade clone. He actively tries to help his fellows, but his experiences have left him hardened and perfectly willing to kill.
- Honor Before Reason: Quinn's double would rather remain blind than harvest a clone. Mallory takes it to the other extreme.Mallory: Colin says you give up things for your family. If my brother needs my eyes, he can have them.
- Irony: The Mallory clone does give Quinn's double his eyes, but by acting like a seeing eye dog."I'm his eyes."
- Last-Name Basis: The Quinn clone is known only as "Mallory."
- Riddle for the Ages: What advice did Quinn give his double before the slide?
- Take a Third Option: Quinn's double won't accept a transplant while Mallory is willing to give him his eyes. In the end, Mallory becomes something of a seeing eye-dog to him.
- Take That!: Rembrandt buys a biography of Richard Nixon "to see if there are 18 missing pages."
- Taking the Bullet: Mallory for Michael. He survives, though.
- Wide-Eyed Idealist: Downplayed. Colin believes people shouldn't hurt another to help themselves, but it's clear he recognizes not everyone feels that way.
