- Lucien LaCroix: [Opening credits narration] He was brought across in 1228, Preyed on humans for their blood. Now he wants to be mortal again. To repay society for his sins, To emerge from his world of darkness, From his endless Forever Knight.
- [Examining the contents of Tracy's refrigerator]
- Javier Vachon: You arrange this stuff alphabetically?
- Janette: Surely you are old enough by now to understand the difference between "not guilty" and "innocent."
- Schanke: I'm curious what happens when we die, but I don't go on reconnaissance missions to find out!
- Det. Nick Knight: Science won't help you to understand what I am, or the hell of an existence I've locked myself into.
- Javier Vachon: So, what is this now? Every time you run across something really weird, you run to your supernatural chum, Vachon, for the inside dope?
- Tracy Vetter: Well, you're the only supernatural friend I have.
- Janette: That's not enthusiasm, it's desperation. They all dance as if Father Time were shooting bullets at their feet. Which, I suppose, he is.
- Tracy Vetter: I dated him once.
- Det. Nick Knight: Was it serious?
- Tracy Vetter: No, I mean I dated him ONCE.
- Lucien LaCroix: Well I have seen stranger things in my time - men who walk through fire, children born speaking long-dead languages, and Harry Houdini had rather a nifty trick with handcuffs and a tank full of water.
- Capt. Amanda Cohen: I think you're very lucky to have such good friends. Appreciate them, Knight. It's what makes life worth living.
- Natalie: So, did you learn anything while you were dying on me?
- Det. Nick Knight: Yeah, I learned that I have to live with the choice I made 800 years ago, and that forgiveness is not something you ask for, it's something that you earn here, among the living.
- Det. Nick Knight: I need a favor, Nat.
- Natalie: I don't know, Nick, favors for you usually involve more than "Can I borrow your car?"
- Det. Nick Knight: I'll need that too.
- Javier Vachon: First night, first feeding, you wake up so hungry, you'll do anything for the blood you need. Take anyone. Enemy, friend, lover. If your first kill isn't human, you don't hunger for humans.
- Det. Nick Knight: I take it you need something.
- Javier Vachon: Your doctor friend.
- Det. Nick Knight: What for?
- Javier Vachon: I've got a sick friend. I need her help.
- Det. Nick Knight: She's not that kind of doctor.
- Javier Vachon: I hear she's pretty good with the dead. And the undead. Look, I can't take this one to the hospital. In the emergency room, what am I'm gonna tell them? He's allergic to penicillin, garlic, sunlight, crosses, and food. He's about four hundred and fifty and he can fly.
- Det. Nick Knight: Don't. Don't get too close to me.
- Natalie: Why? You want to hurt me? Kill me?
- Det. Nick Knight: No. But I might anyway.
- Natalie: Nick, I'm in the habit of believing 10 unbelievable things before breakfast every day, starting with you.
- Lucien LaCroix: I can see by the old clock on the wall that it's very nearly Father's Day. So, tonight's question is - what is a father?
- Det. Nick Knight: And you're not afraid?
- Dr. Natalie Lambert: Fear is based on ignorance. I'd rather try to understand. Understand who you are... *what* you are.
- Det. Nick Knight: You're a unique woman.
- Dr. Natalie Lambert: No. I'm a scientist.
- Det. Don Schanke: You're not talking about a six-year-old here.
- Det. Nick Knight: We *could* debate that, Schanke.
