Repairman: Just part of my job.
Seth Frank: I hate it when people say that. "Just part of my job." It is your fucking job.
Seth Frank: There's one thing I forgot to tell you. I live alone.
Luther Whitney: I'm your substitute driver tonight, Mr. Sullivan.
Luther Whitney: I've got to go have my pacemaker checked, it has been so exciting talking to you.
Seth Frank: Kate, he's on the run and he's scared. And he's right to be scared, 'cause he's gonna get caught. You don't know the heat on this.
Seth Frank: Pacemaker, my ass.
Art Student: You work with your hands, don't you?
Kate Whitney: Quit wasting my time. He doesn't want you to find him, you're not gonna find him.
Seth Frank: You're saying what? He left town, he skipped the country? What?
Kate Whitney: I'm saying, you won't recognize him. I'm saying, he could be right around the corner.
Luther Whitney: Remember, tomorrow is promised to no-one.
Seth Frank: You know who did it, don't you?
Luther Whitney: So do you. Check your phones.
Kate Whitney: Do you know what it's like to be the only kid in the first grade who got to talk about visiting day?
Gloria Russell: He's got the letter opener. Blood. Fingerprints. Jesus... Think what he can do.
Bill Burton: The man's a thief. A thief who witnessed a murder.
Medical Examiner: Looks like he tried to strangle her.
Seth Frank: He strangled her, then he went to the door to shoot her from behind?
Medical Examiner: He also inspected her vagina.
Seth Frank: He did what? Why?
Laura Simon: Maybe he didn't remember that he did her.
Seth Frank: A strong burglar with a weak mind. Obviously another open-and-shut case.
Bill Burton: Miss Russell, I should've called the police that night but I was weak. You convinced me to stay silent. I regret that. Know this: every time I see your face, I wanna rip your throat out.
Kate Whitney: But then you go to the police. That's what innocent people do. They go to the police.
Luther Whitney: Sure. And that young man who was just here, he'd believe me over the President, wouldn't he?
Kate Whitney: Well, why should I believe you?
Luther Whitney: Because I swear to you, Kate. I swear to you on Mattie's grave. Yeah, that's right. Your mother's grave, I'd kill myself before I lied about that.
Kate Whitney: Oh Jesus, Luther.
Luther Whitney: Yeah, I know.
Answer: The female detective states the carpet is spotlessly clean, indicating they had performed an intense cleanup not shown on camera so they would no doubt cover the staircase as well and wipe it clean of prints.
