- Det. Steve McGarrett: [Spoken with contempt towards Donna Wales] Y'know, it's funny. Your best friend is dead. You could help us find out why and how. But you couldn't care less. That's pretty cool, baby. Pretty cool.
- Det. Steve McGarrett: Edie Hastings?
- Professor David Stone: Wonderful girl. Beautiful child.
- Det. Steve McGarrett: You knew she was on drugs?
- Professor David Stone: I knew she was searching for who she was. The light. Joy. The vision of truth. The central experience.
- Det. Steve McGarrett: By turning on and tuning out?
- Professor David Stone: Out of the rat race? The sordid little games you people play and call life? Yes, Mr. McGarrett, dropping out.
- Det. Steve McGarrett: [Steve has found pills among Eadies affects] Five will get you ten they're methamphetamine... Speed.
- Det. Steve McGarrett: You're pretty uptight, Danno.
- Danny: Why not?... She reached out to me... I was inches from grabbing her... Inches!
- Det. Steve McGarrett: Let's keep the next one from slipping away.
- Det. Steve McGarrett: [Talking to his men] Who turned on Eadie Hastings is the only thing that concerns us now.
- Professor David Stone: You've been a charming and stimulating breakfast companion, Mr. McGarrett... And I've thoroughly enjoyed our little philosophical conversation, but the next time... Bring a warrant.
- Det. Steve McGarrett: I'll do better than that... I'll bring a pair of handcuffs.
- Professor David Stone: [Eadies father wants David to take speed] We'll both turn on... And learn to love rather than kill one another.
- Professor David Stone: [David thinks Donna is laughing at him] Laughter should be beautiful... You make it ugly.
