Enterprise finds a pod trapped in an anomaly, and the man inside holds several secrets about the Expanse.
Tropes in this episode include:
- All Myths Are True: Archer and T'Pol discuss the Triannon creation myth again, and begin to wonder if it has a basis in fact.
- Distracted by the Sexy: T'Pol sees Amanda slap Trip's ass during the sparring session, which distracts her long enough for her partner to deck her.
- Explosive Instrumentation: Bizarrely crossed with Bullet Time—the helm sends out a burst of sparks in slow motion when Enterprise is in the Negative Space Wedgie.
- Green-Eyed Monster: T'Pol is clearly jealous of Trip and Amanda, despite trying to deny it.
- Inappropriately Close Comrades: T'Pol says that Trip and Corporal Amanda Cole are this. Trip counters by saying that since Cole's a MACO and not Starfleet, it's okay.
- Interservice Rivalry: Things come to a head between Malcolm and Hayes. Malcolm even tries to say that the MACOs' combat experience comes from simulator training on Earth, ignoring that they have fought numerous skirmishes against the Xindi.
- It Has Only Just Begun: Before disappearing, the alien test subject gives a last message to Archer:"When the Xindi destroy Earth, my people will prevail!"
- Jack Bauer Interrogation Technique: Downplayed—rather than actively cause him pain, Archer makes Phlox hold off on giving pain meds to the patient to make him start talking.
- No-Sell: Energy weapons are useless against the alien.
- Reverse Polarity: Malcolm and Hayes do this on the warp core to stop the alien.
- Screw This, I'm Outta Here!: A Downplayed version — a Red Shirt happens to walk down the corridor where Malcolm and Hayes are fighting and decides to go back the way he came.
- That's an Order!: A pissed-off Archer orders Malcolm and Hayes to settle whatever problem they have with each other."Settle it! That's an order!"
- They Do: Trip and T'Pol.
- Unwanted Rescue: The alien in the pod, who starts dying just after his rescue.
- Wham Episode: The Sphere-Builders make their debut, and Trip and T'Pol finally hook up after half a season of Unresolved Sexual Tension.
- What the Hell, Hero?: Archer chews out Malcolm and Hayes for fighting.
- With Due Respect: Hayes uses this line on Malcolm, who does not consider his behavior very respectful.
