- Dr. Chet Walker: [after his wife has asked if it is all right to leave their 6 year old daughter playing alone outside while monsters are murdering people in the streets] There seems to be some sort of definite pattern. Can't put my finger on it, but I do know that Hennessey and McGraw were killed for a reason.
- Joyce Walker: Well, it's all right then?
- Dr. Chet Walker: Well, for a while. I don't think they've gotten around to indiscriminate killings yet.

- Frank Buchanan: Not just people, Steigg. Particular people. And I'll get 'em. Every single one of them.
- Dist. Atty. MacGraw: What are you doing in here?
- Frank Buchanan: I'm from Buchanan. If you know that, you know why I'm here.
- Frank Buchanan: [Rips away car steering wheel]
- Frank Buchanan: It's no use, MacGraw. I said I would live to see you die. I am watching you now...
- Joyce Walker: [Chet comes up behind Joyce and smacks her on the butt as she bends over to get the paper, stands up and turns around] You!
- Dr. Chet Walker: Who were you expecting? Don't tell me strangers are...
- [she kisses him]
