- Catherine Willows: Tequila will always remind me of Señor Frog's.
- LVPD Capt. Jim Brass: Which one?
- Catherine Willows: Cancun. My honeymoon. My dime.
- LVPD Capt. Jim Brass: Well, if you ever want to go back, it's on me.
- Catherine Willows: Is that a proposal?
- Catherine Willows: What are you thinking?
- Gil Grissom: Led Zeppelin.
- [pause. Grissom glances up the stairs]
- Gil Grissom: Stairway to Heaven.
- Catherine Willows: [to Ray Lester] When, exactly, was the last time that you had sexual intercourse with your late wife?
- Ray Lester: Four years ago.
- [holds up his hand]
- Ray Lester: Rosy Palm and Thumbelina are the only action that I get.
- Catherine Willows: Uh, wow. You know, uh, a joke like that doesn't quite seem appropriate for a distraught husband.
- David Phillips: It's like the Red Sea in here.
- Gil Grissom: The Red Sea's not red, David.
- David Phillips: No, it's blue from afar and transparent when held in hand, like any other body of water. I was just speaking figuratively.
- Greg Sanders: [about the scent from one of the paramedics' shoes] Whew! Did you ever hear of Odor Eaters?
- LVPD Capt. Jim Brass: Okay, the husband says he fell asleep, he woke up, his wife was dead.
- Gil Grissom: He's a good sleeper.
- LVPD Capt. Jim Brass: Mr. Stein, does your son-in-law have a temper?
- Grandpa Stein: Do I have to answer that?
- LVPD Capt. Jim Brass: You just did.
- Gil Grissom: That's odd. A man and a woman who don't share a bedroom arrange to have a night alone, send their daughter to a relative, go out to dinner, have drinks by the pool, but they sleep in separate bedrooms.
- Sara Sidle: Maybe one of them snored or had insomnia or liked to work at night.
- Gil Grissom: Or maybe they were suffocating each other and he couldn't breathe.
- Al Robbins: [about Becky Lester's injuries] Exsanguination from five lacerations: two to the forehead, one to the right temple and two to the occipital bone.
- Gil Grissom: Are they consistent with a fall?
- Al Robbins: Yes, but I'd expect to see hand fractures as a result of the impact, and there are none.
- Gil Grissom: Are they consistent with blunt force trauma?
- Al Robbins: Sure, but if the husband bludgeoned her, there'd be fractures to the skull.
- Gil Grissom: And there are none.
- Al Robbins: None.
- Gil Grissom: Well, you've given me a lot of information, doc, and none of it very helpful.
- LVPD Capt. Jim Brass: Husband and wife, home alone, all that blood, shaky alibi. Plus, he says, "He just looks guilty."
- Gil Grissom: How does one "look" guilty?
- Nick Stokes: [to Catherine] Quick. How many teeth in the human mouth?
- Catherine Willows: Without wisdoms? 28.
- Nick Stokes: Yep, and the 28 teeth in Becky's mouth do not match the bite impressions on her husband's body.
- Catherine Willows: I guess Ray found himself another set of pearly whites.
- Ray Lester: Look, I loved my wife, but, a year into our marriage, she told me that she wasn't into sex anymore. And, uh, she went frigid on me. Asked me to move into the other bedroom.
- Catherine Willows: And you were okay with that?
- Ray Lester: Well, I kept hoping things would get better and we had fun and we respected each other. And she was a great mom to Susan.
- Catherine Willows: I'm still confused about the bite marks.
- Ray Lester: I found a way to make our relationship work.
- Catherine Willows: You found yourself a vampire?
- Warrick Brown: So both of Ray's wives end up dead at the bottom of the stairs with lacerations to the head.
- Al Robbins: If my full autopsy confirms murder, you may be looking at the first serial stairway killer.
- Gil Grissom: [to ADA Sinclair] For the record, I think you're filing prematurely.
- A.D.A. Jeffrey Sinclair: As always, I value your opinion, but I'm confident in our decision to move forward. But, come on, Grissom. Granted, the first death was a natural, but two dead women married to the same guy found in a stairwell? Lightning doesn't strike in the same place twice.
- Gil Grissom: Actually, it does. The Empire State Building gets struck 20 times a year.
- Catherine Willows: [to Ray Lester] You knew.
- Ray Lester: What?
- Catherine Willows: Your daughter killed your wife and you knew it.
- Ray Lester: I don't know what you're talking about.
- Catherine Willows: Susan attacked Becky as soon as she went into the house, but you admitted to having another drink. You would've heard the attack.
- Ray Lester: I'm sorry, but that's what happ...
- Catherine Willows: You went into the house and found Susan wiping blood off of her hands. You sent her back to her grandfather's. You came up with a story to tell the cops, and then called 911. You were protecting your daughter and now she's protecting you.
- Ray Lester: You can't prove it.
- Catherine Willows: Well, either way, you have to live with it.
