Aired Friday 9:00 PM Mar 11, 2011 on CBS



  • Trivia

    • Goof: Texting is not synchronized with the on screen information when the students are sending sms's from the crime scene.

    • A scene from episode 3x18 Sleight Out Of Hand can be seen during this episode.

    • Jo's badge number is 1879.

    • Goof: The first time that the toilet seat is shown there is no yellow substance on the shoe prints.

    • Goof: The first time that Olivia Prescott's death is reconstructed, the blood spatter on the mirror is nothing like the one at the crime scene when Danny is processing it.

    • Sid has a niece who is around 20 years of age.

    • It is unlikely that no one had noticed about the sex exchange (Olivia in particular, who didn't realize until she removed the book from the shelf) going on at the library seeing as the table was repeatedly slamming against the wall and both kids were panting and moaning quite loudly.

    • Jo was a cheerleader in high school. She was made fun of because of her braces.

    • Goof: Lindsay only needs to randomly click on the desktop to prompt Archfords's Academy website, the exams schedule page (which she is looking for) no less.

    • Archfords's Academy has a $80,000 tuition fee.

    • Lindsay's high school Math teacher was called Mr Hamilton.

    • Adam's 'What up?', which he started using in episode 4x01 Can You Hear Me Now? has become a recurrent trademark, same as Danny's 'Boom'.

    • Goof: We see Danny and Lindsay doing bacterial and fungal cultures in petri dishes from air aspirations from different parts of the school and getting results almost immediately. Bacterial and fungal growings, even in an incubator, take at least 2 days to show something significant. Most of the bacteria resulting can't be identified under a simple microscope.

  • Quotes

    • Flack: (About the kids snapping shots of the victim with their cell phones) The digital grapevine is in full effect.

    • Mac: (About the kids gathered around the vic with their cell phones in hand) Any of them catch anything besides a postmortem snapshot?

    • Mac: She was murdered right here on the school grounds.
      Flack: Usually, you tell your kids to be safe walking home from school, not through it.

    • Mac: (Reading the Archford Academy's motto) Ad Vitam Paramus. Means 'we are preparing for life'.
      Flack: Well, someone at Archford had a different idea.

    • Lindsay: Did you see the looks on those kids' faces? They're never going to forget this day. I still remember every detail of the night my friends were murdered.
      Mac: Let's hope one of them remembers every detail of what happened here.

    • Danny: This is her backpack right here. Seems like she was a smart girl. Calculus C.
      Jo: Lord. I never knew there was an A or a B.

    • Jo: Oh, we've got shoe tread marks on the toilet seat.
      Danny: That's kind of a weird way to do your business, no?

    • Mrs. Prescott: Is there any way this could be an accident? I mean, maybe she fell and hit her head, right?
      Jo: I'm sorry, but everything seems to indicate that this was a homicide.
      Mrs. Prescott: It just... it doesn't make any sense.
      Jo: Never does.

    • (Sid is lost in thought by the vic's body)
      Mac: Sid?
      Sid: Uh, I was just thinking about my niece. She's not much older than our victim here.

    • Sid: It's not a tattoo, and it's the only one on her body but I just find it odd (Shows an 'F' imprinted on the victim's right thumb)
      Mac: How does the smartest girl in school get an F?

    • Lindsay: Can you imagine Lucy at a school like this?
      Danny: Girl was just murdered here, so I'll try not to.
      Lindsay: It's a five-star education. Courses built around the specific developmental needs of your child, an equal emphasis on Arts and Science and a college acceptance rate that's in, like, the 95th percentile.
      Danny: You memorize the brochure?
      Lindsay: I'm just trying to be prepared. It's our daughter's future.
      Danny: All right, well, I got news for you, sweetheart. Lucy's gonna go to an old-fashioned, nice public school like I went to, okay? That's her future. Not with these kids.
      Lindsay: Okay.

    • Danny: I found a book of Greek tragedies in her backpack
      that had one of those Dewey magic codes on the binding, like a library book.
      Lindsay: The Dewey Decimal System?
      Danny: Yeah. I could never figure that out.
      Lindsay: Well, maybe if you'd gone to Archford.

    • Lindsay: Is that an ass print?
      Danny: Honey, what?

    • Danny: (After reaching the conclusion that some kids were having sex at the library) Looks like there was a little extracurricular activity going on back here, huh?

    • Lindsay: That was a quick print search. Think I'm gonna throw away that Archford brochure. It's a student with a record.

    • Lindsay: (After finding porn movies in Benjamin Gold's locker) Someone's getting detention.
      Danny: Whoa. What are you teaching these kids here?

    • Benjamin Gold: (In one of his movies) How do you like Principal Andrews' BIG exam?
      Mac: (Stops the movie) Principal Andrews' BIG exam? That's clever.
      Benjamin Gold: What can I say? I'm a professional.
      Mac: Seems a little cocky for a kid who's looking at jail time.

    • Flack: Were you in the library today?
      Becky: Yeah. But I'm... I'm there every day.
      Flack: Got a lot of work done then?
      Becky: Yeah.
      Flack: Yeah. I didn't realize having sex was considered homework.

    • Becky: Ben told me to meet him in the library. He had his camera all ready to go. Hit record, dropped his pants and I...
      Flack: Okay. Just fast forward to the part where Olivia Prescott caught him with his pants down.

    • Jo: Dog ate your homework? What's up?
      Adam: Okay, check this out. I was processing Olivia Prescott's clothing and I found this weird gray dirt on her blazer, so I ran it through GCMS and I found a high concentration of sodium, potassium, magnesium and chloride, which is, erm... well, it's, eh... it has the same chemical consistency as, uh, Martian soil.
      Jo: What?
      Adam: Soil found on Mars.
      Jo: Okay, so I should have Flack send out an APB on what? 5"2', big head, almond-shaped piercing black eyes, last seen leaving Archford Academy in a flying saucer?

    • Mr. Booker: Emmy Thomas. She's an incredibly bright girl, but... frequent target of her fellow classmates.
      Hawkes: Why's that?
      Mr. Booker: Well, the blazers aren't the only form of unification amongst these students, detectives. From what I can tell, Archford breeds a specific type of teen.
      Mac: We're well aware of the students' academic achievements.
      Mr. Booker: No, I'm talking about outside the classroom. Socially, these kids can be pretty brutal.

    • Emmy Thomas: They were obviously talking about me so I stood on the seat. Pretty good at being invisible when I need to. When they were finished ripping me apart, I left.
      Hawkes: We're gonna need those girls' names.
      Emmy Thomas: Cynthia Evans and Rachel Halstoy. When they're not puking in the toilet, they're usually at cheer practice. Is there anything else that I can do for you, detectives, or are you done unpacking my personal life?

    • Jo: Flack interviewed the two cheerleaders and they both admitted, without remorse, that they made fun of Emmy in the bathroom, knowing the whole time she was there. That is so cruel. If they were on my squad, I'd kick'em to the D team.
      Lindsay: You were a cheerleader?
      Jo: Don't act like you weren't.

    • Jo: All the answers to the test. It's a cheat sheet.
      Hawkes: It's impressive. I mean, not like I ever cheated or anything.

    • Hawkes: Running a search through AFIS now. Chances are it's another student.
      Mac: Well, they might not be in our database. They can't all be as enterprising as Benjamin Gold.

    • Adam: It's not impossible, just ballsy.
      Danny: What? What is it? What are you talking about?
      Adam: It's called Remote Desktop Access. It's a program that can be installed on pretty much any computer. You indicate the host computer... then the client computer. Then you have direct access to their desktop. Wait for it to sync and...
      Danny: Is that Mac's?
      Adam: Yeah.
      Danny: That's pretty impressive.

    • Lindsay: Just got off the phone with Archford. They've never suspected any of their students of cheating.
      Jo: They never suspected any of their students of murder, either. Every school has cheaters.
      Lindsay: I guess they're just trying to preserve their reputation. They've got to do something to justify those $80,000 tuition checks.

    • Allen Wilson: The lava lizard's color-changing abilities are not unique to its environment... its environment being the Atacama Desert in Chile.
      Flack: You know, Allen, I'm not a biologist or anything but I'm pretty sure chameleons change colour just the same.

    • Flack: (To Allen Wilson) You seem like a smart kid. Not smart enough to remove one important thing from your water bottle cheat sheet. You forgot to remove the original bar code. Because of that, we were able to track the bottle back to its manufacturer, check their shipping logs, find out which supermarket it was sold in. Good thing Mommy uses credit cards.

    • Allen Wilson: The teachers are smart, but technologically illiterate.

    • Flack: You got into Georgetown. Why help her cheat?
      Allen Wilson: Because even an Archford education can't teach you how to win five minutes with a girl like Olivia.

    • Jo: People commit murder for one of three reasons: money, revenge and... jealousy.

    • Jo: When I was your age, I had a big old mouth full of braces. Kids made fun of me all the time but I had a backbone like yours and I never let it get to me.
      Emmy Thomas: Good for you.

    • (About Allen Wilson)
      Emmy Thomas: He's not my boyfriend.
      Olivia Prescott: But I see the way you look at him, Emmy. It's the same way he looks at me.

    • Emmy Thomas: For years, I've had people make fun of me. And that's okay. At least I was aware. It made me sick to my stomach seeing Olivia batting her eyes at Allen in exchange for his hard work. He risked everything for her, and she... he didn't deserve it.

    • Emmy Thomas: I regret killing Olivia. I really do. But what I don't regret is standing up for my best friend.

    • Jo: You think Allen Wilson had any idea?
      Mac: That his best friend was capable of murder?
      Jo: That his best friend was in love with him. It's funny the things we choose not to see.
      Ma: Yeah, well, wouldn't hurt for parents to open their eyes, either.

    • Jo: You just wish someone would have told Emmy that high school isn't the end of the world. It's just the beginning.
      Mac: Guess that's the kind of lesson you can't learn in school.
