A terrorist attack destroys the Earth embassy on Vulcan. Archer and T'Pol embark on a trek through the desert to find those responsible.
- Actual Pacifist: The Syrranites, which is why it doesn't make sense when they're accused of the embassy bombing. And then it turns out that they were framed.
- Artistic License Military: Corporal Asquith is wearing a Starfleet uniform, despite their use of naval ranks. He should've been a MACO.
- Bears Are Bad News: Archer and T'Pol have a run-in with a seh'lat, the Vulcan equivalent. Arev saves them with the same trick that Obi-Wan used on the Tusken raiders.
- Right before dying, Arev melds with Archer while saying the Vulcan word for "remember." Sound familiar?
- The questions that Arev asks Archer are right from Spock's retraining test.
- Arev realizes that Archer is the man who exposed the spy station at P'Jem. This softens his attitude towards both Archer and T'Pol.Arev: You're the human responsible for the destruction of the monastery at P'Jem.
Archer: Is that going to be a problem?
Arev: The High Command defiled P'Jem when they used it to spy on Andoria. You exposed their hypocrisy.
- Character Death: Admiral Maxwell Forrest dies in the attack.
- Deadpan Snarker: Archer trying to bluff his way out of Arev's questions.Arev: Who said "Logic is the cement of our civilization with which we ascend from chaos, using reason as our guide"?note
Archer: I'm new at this. You tell me.
Arev: Perhaps something simpler. What is Kiri-kin-tha's First Law of Metaphysics?noteArcher: (beat) I'm familiar with Newton's First Law of Motion. I imagine they're pretty much the same.
- Death Glare: Soval shoots Trip a skunk eye for hovering over him during the mind meld.
- Does This Remind You of Anything?: A terrorist attack that leads to overbearing and intrusive new security measures. That sounds familiar...
- Due to the Dead:
- Archer stands over Forrest's coffin in the storage bay.
- Archer and T'Pol bury Arev before continuing to the sanctuary.
- Foregone Conclusion: T'Pau obviously isn't going to be guilty of bombing the embassy, since she's a well respected and noted public figure in "Amok Time".
- Gallows Humor: While trying to examine an unexploded bomb, Malcolm remarks to Travis that at least if it detonates, they'll never know.
- Heroic Sacrifice: Forrest selflessly pushes Soval out of the path of an explosion.
- I'm Dying, Please Take My MacGuffin: Right before dying, Arev melds with Archer to transfer Surak's katra.
- Impractically Fancy Outfit: T'Pol continues to wear her tight catsuit instead of Vulcan robes which would be more pragmatic in the desert.
- Jerkass Has a Point: Soval explains to Forrest why Vulcans are wary of humans. Both suffered through destroyed civilizations, but while Vulcans took a thousand years to rebuild, humans did the same in less than 100."There are those on the High Command who wonder what humans would accomplish in the century to come, and they don't like the answer."
- The Needs of the Many: Soval says this before revealing himself to be a melder, potentially throwing away his career to get crucial information from a comatose Red Shirt.
- Not So Different: Archer laughs a little when T'Pol tells him that with the original teachings of Surak lost, they've been subject to interpretation and disagreement ever since. He doesn't find it amusing, he says—he finds it familiar.
- Not So Stoic: Arev chuckles a bit when Archer tells him what the High Command thinks of the Syrranites.
- Oh, Crap!: Travis when he finds an undetonated bomb in the rubble, and then him and Malcolm when it arms itself to blow up.Travis: That can't be good.
Malcolm: Oh damn!
- Paper-Thin Disguise: Arev easily shoots holes in Archer's claim to be a human student studying Vulcan philosophy, when he can't answer some basic questions.
- Planet of Hats: Rather, it's humanity's lack of a hat that concerns the Vulcans.Soval: We don't know what to do about humans. Of all the species we've made contact with, yours is the only one we can't define. You have the arrogance of Andorians, the stubborn pride of Tellarites, one minute you're as driven by your emotions as Klingons, and the next you confound us by suddenly embracing logic.
Forrest: I'm sure those traits are found in every species.
Soval: Not in such confusing abundance.
- Present Company Excluded: Archer giving Trip orders before beaming down to the Forge with T'Pol:"...And whatever the Vulcans tell you, believe the opposite." (glances at Soval) "Present company excepted."
- Revealing Cover-Up: Phlox reexamines the DNA found on the bomb, and finds that it's actually a sample from when T'Pau was registered as a baby.
- Run or Die: The only way for Archer and T'Pol to survive the dangers of the Forge, from a seh'lat to an electrical sandstorm.
- That's What I Would Do: Malcolm suggests that the undetonated bomb might arm itself upon being scanned or transported, saying that he would design a bomb to do so. He's quickly proven right when he scans the bomb and it starts beeping.
- Took a Level in Kindness: Soval becomes kinder and more open with Archer and his crew after the attack.
- Wide-Eyed Idealist: Soval recalls how Forrest genuinely believed in the alliance despite all the friction and was proposing joint missions.
