This episode contains examples of:
- Accent Relapse: Felix's "truth voice".
- Body Double: Nealon kidnaps Krystal so she can be used as Rachel's double while she's abroad.
- The Chessmaster: Rachel makes a come-back this episode. First she manipulates Sarah into getting her Krystal's identity, then she gets Nealon to swipe Ethan Duncan's book, then she tricks Delphine into thinking she's in a coma so she can go abroad, using Krystal as a body double. And no one but Nealon has any idea that she's even capable of this.
- Cock Fight: Donnie confronts Jason about his feelings for Alison, resulting in a brawl in the back of the store.
- A Day in the Limelight: The Krystal character was originally written as a one-off Red Shirt clone, glimpsed on security-cam footage, for the Season 3 opener - whose original fate would be losing her head at the hands of Rudy and Seth. After filming the scene, Manson and Fawcett decided the character was too good to kill off
, and fleshed her out enough to anchor an entire episode. - Eyepatch of Power: Rachel gets one in this episode, as a sign that she's slowly returning to her old self.
- Fake Canadian: In-Universe, Felix dumps his British accent in order to get close to Krystal.
- Out of universe, this is Jordan Gavaris (a Canadian) playing a Brit playing a Canadian.
- Give Him a Normal Life: Sarah doesn't want Krystal to get dragged into the clone drama, so she tells Felix not to tell her anything when he goes undercover.
- Hidden Depths: When Felix looks through Krystal's locker, he finds evidence that she's been investigating Rudy and Seth, and might be coming close to figuring out what's going on. Not what you'd expect from a ditzy manicurist. There are also hints that she's a very lonely person, since the only people she can talk to about her traumatic experience are her customers.
- Honey Trap: Felix poses as straight and gets a mani-pedi from Krystal to get her passwords and her wallet.
- I Have Your Wife: Well, cat. Rudy forces Scott to give him the book by threatening his cat, Denise.
- Incompatible Orientation: Krystal develops a bit of a crush on Felix. Not only is he gay, but she looks like his (foster, but still) sister.
- Locked Out of the Loop: Both Sarah and Delphine try to keep Krystal ignorant of the cloning, but at least Sarah does it out of compassion. Felix almost spills the beans because he thought she deserved to know.
- MacGuffin: Everyone scrambles for Ethan Duncan's book, or at least a copy of it.
- Motor Mouth: Krystal really likes to talk. At one point she even lampshades it.
- Nice Job Breaking It, Hero:
- Sarah plays right into Rachel's hands, resulting in Krystal being kidnapped and placed in a medically-induced coma.
- Cosima and Scott's attempts to hide Duncan's book from Delphine results in Rudy stealing it and Nealon stealing the copy.
- Out-Gambitted: Clone Club was outsmarted by Delphine, who was then outsmarted by Rachel and Nealon.
- Playing Sick: Rachel pretends to collapse so Nealon can have an excuse to take her back to Dyad, so she can switched out for Krystal, and so everyone would think she was incapacitated.
- Running Gag: Rachel is still not entirely comfortable when presented with a sharpened pencil.
- Valley Girl: Krystal — blonde hair, lots of pink, cutesy accessories, pictures of hot guys on her locker... the works.
- Weirdness Magnet: Even before her close encounter with the Castor clones, Krystal realizes that a lot of really odd things have been going on in her life.
- What the Hell, Hero?: Delphine calls Cosima out for not trusting her with the book.
- Wham Line: "In London town we all fell down, and Castor woke from slumber."
