- Sub-Commander T'Pol: Just because they smile and eat chicken doesn't mean they've learned to master their emotions.
- Commander Charles 'Trip' Tucker III: I've learned about your marriage customs, how your parents arrange the whole thing when you're young, stuff like that. But... what about... you know...
- Kov: Ah, you mean sex?
- Commander Charles 'Trip' Tucker III: [hemming and hawing] It's not a topic I've heard Vulcans discuss.
- Kov: Well, we do have it if that's what you're asking.
- Tolaris: [contemplating a nebula] Look at that. I've never seen anything so beautiful. You probably consider that an emotional reaction.
- Sub-Commander T'Pol: Not necessarily. It is aesthetically pleasing.
- Tolaris: "Pleasing". Coming from you, that's practically an outburst.
- Sub-Commander T'Pol: Last night I neglected to meditate before I went to sleep. As a result, I awoke feeling... agitated. All I need is an injection of inoprovalene. 25 milligrams should suffice.
- Dr. Phlox: Very well... "Doctor".
- Tavin: Logic is an essential part of Vulcan existence. But it has to complement emotions, not exclude them.
- [Archer has provoked Tolaris into a violent reaction]
- Tolaris: You planned this.
- Captain Jonathan Archer: [groaning] If I'd known I was gonna get thrown across the room that hard... I might have tried a different approach.
- [Archer visits T'Pol in her quarters during her meditation]
- Captain Jonathan Archer: Feeling any better?
- Sub-Commander T'Pol: Has the Vulcan ship left?
- Captain Jonathan Archer: About twenty minutes ago.
- Sub-Commander T'Pol: Then, yes. I'm feeling better.
- Captain Jonathan Archer: [referring to T'Pol's meditation] You do this every night?
- Sub-Commander T'Pol: Every night.
- Captain Jonathan Archer: I think... I finally understand why.
- [Trip and Kov are talking over lunch]
- Commander Charles 'Trip' Tucker III: Where'd you hear that?
- Kov: A Vulcan anthropologist told me he'd seen the ritual during an Earth expedition.
- Commander Charles 'Trip' Tucker III: They're not trying to *kill* the quarterback. They're just trying to keep him from throwing the ball or running with it. It's only a game, not a fight to the death.
- Tolaris: My mind to your mind. Your thoughts to my thoughts. Our minds are merging, our minds are becoming one.
- [first Vulcan mind meld involving a regular character in Star Trek history]
- [Tucker is trying to persuade Kov to contact his father, who is dying. After failing with the direct approach, he tells Kov instead about a girl he once had a crush on]
- Commander Charles 'Trip' Tucker III: It's been more than twenty years, and I'm still kickin' myself for not asking that girl to dance. You probably don't know this, but... regret is one of the strongest emotions, and... one of the saddest. I have a feeling you haven't had a brush with it yet; but it sounds to me like... you're pretty close. That's something you might want to avoid.
- Sub-Commander T'Pol: Captain. Do you... dream?
- Captain Jonathan Archer: Sure. Sometimes they're even in color.
