- Greg Sanders: I'm like a sponge. I just absorb information.
- Gil Grissom: I thought that was my line.
- Greg Sanders: Yeah, and I absorbed it.
- Gil Grissom: Male cat urine. To us: smelly. To female cat, it must be like aftershave.
- Catherine Willows: Me-ow.
- Nick Stokes: Hey.
- Sara Sidle: [lively] Hey.
- Nick Stokes: Wow, you look...
- Sara Sidle: Happy?
- Nick Stokes: Smug, acually.
- Gil Grissom: [to Catherine after witnessing a child ignoring her mother] My mother may have been deaf, but she was still the boss.
- Greg Sanders: [Grissom and Catherine walk into Greg's lab to see him rocking out to blaring rock and roll music] I could have been a rock star.
- Gil Grissom: There's still time, Greg. Tell us about the foreign substance we found in the vic's wound track.
- Greg Sanders: Uh, well, I like to rub it all over a lady's body. Even better... I, uh... like it when she rubs it all over me. And it's also used as a stool softner.
- Catherine Willows: It's also the only open lead in our case. Spit it out, Greg.
- Greg Sanders: Mineral oil.
- Gil Grissom: Possibly used as a preservative to prevent rusting of high-carbon steel.
- Catherine Willows: Like the blades of knives.
- Greg Sanders: Old knives. New ones are made from stainless steel. Yeah, I'm like a sponge. I just absorb information.
- Gil Grissom: I thought that was my line.
- Greg Sanders: Yeah, and I absorbed it.
- Catherine Willows: Okay, so... knives, screwdrivers, ice pick, letter opener. We're looking for a weapon with a splash of mineral oil. I'll grab the ALS.
- Greg Sanders: An ALS. For mineral oil?
- Gil Grissom: Mineral oil fluoresces at 525 nanometers when filtered through a kv590. A little more absorbing... a little less rock and roll.
- Catherine Willows: Well... an old lady wears flats or slippers. I can't imagine that this vic entertained.
- Gil Grissom: You got to be careful with isolation. It can escalate. Before you know it, you're the crazy cat lady living in the rundown house.
- Catherine Willows: My name's Catherine. What is your name again?
- Jessica Rachel Trent: Jessica Rachel Trent. I'm 8 and a half.
- Catherine Willows: Oh, 8 and a half. So, I bet you're in the third grade?
- Jessica Rachel Trent: Yeah. My teacher's Mrs. Armstrong. She's really nice. Except I hate multiplication especially the eights.
- Catherine Willows: You know, I have a daughter. She hates the eights. too.
- Nick Stokes: You know, when I was 16, I begged my mom for a car. Swore she'd come through.
- Sara Sidle: What happened?
- Nick Stokes: Encyclopedia Britannica.
- Jackie Trent: [after Catherine explains how she found a child's fingerprints on a pen] They're not mine.
- Jessica Rachel Trent: Tattletales burn in hell.
