Castor pursues the Leda clones for original tissue samples. Helena, who is pregnant and imprisoned, is examined by a mysterious new villain. The Castor boys are also out to play, toying with a frightened young woman, Patty, in a sexy switcheroo that ultimately sets Sarah - and Art - hot on the Castor trail. But it's not all fun and games for the Castor boys, as Sarah gleans they may have a mysterious defect that puts their lives in peril.
This episode contains examples of:
- Animal Motifs: The Castor clones have a two-headed horse tattooed on their forearms. In Classical Mythology Castor and Pollux are associated with horses.
- Blackmail: Paul breaks into Cal's new house to tell him to get Sarah off the search for Helena or he'll expose what Cal's been hiding.
- Break the Cutie: Project Castor attempts this with Helena the entire episode, from Miller waterboarding her to Dr. Coady claiming that it was Sarah who sold her out.
- Comically Missing the Point: While being tested by Project Castor, Helena is presented with the following syllogism: "All mangoes are golden. Nothing golden is cheap. All mangoes are cheap. True or false?" Big Eater that she is, she's more interested in the mangoes themselves.
- Cold-Blooded Torture: Miller is extremely casual about water-boarding Helena. He and his fellow soldiers did it to disorient her enough to medically test her.
- Dark Secret: Cal has one that he doesn't want Sarah to know about.
- Deadpan Snarker:Helena (to Miller): I met your brother [Mark]. He's ugly.
- Even Evil Has Loved Ones: Rudy and Seth get along like any other pair of brothers. Rudy gives Seth a clean death and comforts him in his last moments.Rudy: Don't hold on. Go easy.
- Even Evil Has Standards: Helena's water-boarding is stopped when her captors find out she's pregnant.
- Eye Take: Miller's reaction to Helena's Deadpan Snarker zinger. Up to this point, he'd been presented strictly as The Stoic.
- I Have Your Daughter: Rudy holds Kira hostage while interrogating Sarah about Ethan Duncan.
- Incest Subtext: Seth and Rudy are almost disturbingly close. They have no issue engaging in a threesome together.
- Irony: Lampshaded by Coady. She never wanted kids, but ended up raising all the Castor clones as her sons.
- Kick the Dog: Coady tells Helena that her family, particularly Sarah, sold her out because they didn't want her anymore, which is a total lie. Well, Mrs. S did actually sell Helena out, but only because she felt she had no other choice.
- Mercy Kill: Rudy shoots Seth in the chest when his "glitching" gets really bad.
- Oh, Crap!: After Paul gives Cal a warning, he immediately tries to call Sarah but she doesn't pick up.
- Rape as Drama: Seth and Rudy's non-consensual threesome with a terrified Patty.
- Shout-Out:
Word of God confirms
that the logic test/eyeball scan performed on the Castor clones was directly inspired by the Voight-Kamff test in Blade Runner. - Stepford Suburbia: In addition to all the affairs, according to Ramon the other soccer moms are secretly frequent drug users.
- Tattoo as Character Type: All the Castor clones are marked by a two-headed horse on in the inside of the forearm. Mark burns off his tattoo as part of his commitment to Gracie and their new life together.
- That Came Out Wrong: When Donnie wants Alison to give him a fist bump, he say "Fist me". Repeatedly.
- Twin Threesome Fantasy: Subverted. For Patty, it's more of a nightmare than a fantasy.
- We Hardly Knew Ye: Seth dies at the end of the episode.
- What the Hell, Hero?: Art gives this to Sarah when she comes down to the station and impersonates Beth to interview Patty.
- Would Hurt a Child: Rudy points a gun to Kira's head but thankfully doesn't shoot because he gets distracted by the fight between Cal and Seth.
