- Commander Charles 'Trip' Tucker III: You look nice like this - kinda like an old oil painting.
- Sub-Commander T'Pol: ...I'm not old. I will only be 66 years old on my next birthday.
- Commander Charles 'Trip' Tucker III: I can't believe you told me that.
- Sub-Commander T'Pol: You accused me of looking old!
- Commander Charles 'Trip' Tucker III: That's not what I mean. I've been trying to get you to tell me your age since we left Spacedock. Why now?
- Sub-Commander T'Pol: To Vulcans, certain... information is considered intimate.
- Commander Charles 'Trip' Tucker III: Intimate? Hm...
- Sub-Commander T'Pol: [referring to Porthos] Will he be all right?
- Dr. Phlox: Not for a while. Lost his best friend. But it's just a matter of time, he'll be fine again.
- Sub-Commander T'Pol: [to Porthos, but perhaps more to herself] Did you hear that? The Doctor says you'll be fine. It's just a matter of time.
- Andorian: One Reptilian transported to the weapon.
- Commander Shran: Let's make sure he has nowhere to go back to.
- Commander Charles 'Trip' Tucker III: [to T'Pol] My skin's healing faster than yours. I guess you Vulcans aren't so tough after all.
- Sub-Commander T'Pol: My skin hasn't fully healed yet.
- Dr. Phlox: Oh, you're doing fine. Vulcans are obviously more sensitive to the effects of mysterious realms.
- Sub-Commander T'Pol: I guess we're not so tough after all.
- Dr. Phlox: Excuse me?
- Dr. Phlox: It's time for you to work your magic, Mr. Tucker; within five minutes, everyone on this ship is going to start dying!
- Commander Charles 'Trip' Tucker III: No pressure.
- Lieutenant Malcolm Reed: It's done.
- Sub-Commander T'Pol: Done?
- Lieutenant Malcolm Reed: Captain Archer destroyed the weapon.
- Commander Charles 'Trip' Tucker III: Where is he? Is he okay?
- Lieutenant Malcolm Reed: Captain didn't make it, Trip.
- [Enterprise is approaching Earth, as Sato enters the bridge]
- Sub-Commander T'Pol: You should be in your quarters.
- Ensign Hoshi Sato: With all due respect to Phlox, I wouldn't miss this for the world.
- Commander Dolim: [looking on Earth] It's a shame - all that water. The Aquatics would feel at home here.
- [Daniels is trying to talk Archer out of leading the suicide mission to destroy the weapon, because of his key role in a not too distant future]
- Captain Jonathan Archer: My mission is to save Earth, not your "Federation".
- Temporal Agent Daniels: You can't ignore your place in history.
- Captain Jonathan Archer: My place is on that control platform.
- [first lines]
- Commander Dolim: If they had made us the dominant species before the wars, our homeworld would still exist.
- Xindi-Reptilian Lieutenant: And our Avian brothers would still fill the skies.
- Commander Dolim: We should be grateful that the Guardians have finally come to their senses. Once Earth is destroyed, the Reptilians will take their rightful place at the head of a new Xindi empire.
- Sub-Commander T'Pol: Has it occurred to you what's going to happen if Captain Archer fails? If Earth is destroyed?
- Commander Charles 'Trip' Tucker III: Every day.
- Sub-Commander T'Pol: Good. Then you've already come to the conclusion that without Humanity, there's no one to combat these Sphere Builders. Their Expanse will continue to grow, encompassing one system after another, including Vulcan. Your world is no longer the only one in jeopardy.
- Sub-Commander T'Pol: I've always found it distracting to think of death, especially when entering a dangerous situation.
- Dr. Phlox: Hope for the best, prepare for the worst. I don't know about Vulcans, but Denobulans take great pleasure in bequeathing their belongings to far-flung relatives.
- Sub-Commander T'Pol: We're not dead yet.
