I Will Remember You by Sarah McLachlan (edit)

Sara: I know that you killed Kira Dellinger. I just can't prove it.
Hannah: That must be frustrating for you.
Sara: Hannah, Marlon's dead.
Hannah: Wow. That's a really sad and desperate ploy, Sara. It's beneath you. (Sara shows Hannah the photo of Marlon hanging at the windowsill)
Sara: He was doing well here, wasn't he? Making friends, joining a band, falling in love. But you're still a freak, just like high school.
Hannah: You're lying. No. This is a lie.
Sara: His world got bigger, and yours stayed the same, and you killed Kira so you could keep him all to yourself, didn't you? (edit) Marlon: I need to know ... what I did to deserve this.
Hannah: You killed Kira.
Marlon: We both know I didn't do that. (edit) Marlon: I asked Hannah to teach me how to make GHB, and how to get it into Kira. I just wanted to mess her up a bit. I snuck it into Kira's room a few days ago; I still had a key. Hannah must've made a copy.
Sara: I believe you, Marlon. I really do. But the only thing that a jury's going to see is your prints on the lube, your prints on the windowsill, and another dead girl.
Marlon: Why is Hannah doing this to me?
Sara: I don't know. All I know is ... you don't deserve to take the fall for this. And the question is ... are you going to let your sister get away with this and spend the rest of your life in jail?
Marlon: If Hannah wants me in jail, that's where I'm going to be. There's nothing I can do about it. (edit) Sara (about Mrs. Jimenez): What happened? Her husband attack her again?
Ronnie: No. She came involuntarily. It took some convincing, but she's agreed to go to a shelter.
Sara: She won't stay.
Ronnie: Maybe not. But at least now she has a chance. Look, I did it all on my own time, no OT. I know it's not the way you do things, but I think it's part of the job. At least, that's how I want it to be. For me. (edit) Grissom: Hey.
Sara: What are you doing here?
Grissom (walks towards Sara but she backs away): I was going to ask you the same question. Listen, I'm worried about you.
Sara: That just makes this worse. I-I can't talk about this right now. I can't. (edit)

Warrick has a hard time sleeping and takes sleeping medication. Drug name is Zolpidem. (edit) After Sara cuts her name off of her CSI vest she puts the vest into Ronnie's locker. (edit) Catherine's daughter is looking at colleges for further education. (edit) Greg went through a brief goth period to get chicks. (edit) Hannah West is shown lecturing to her brother's "Chem 101" class. As the scene ends, she begins lecturing on the "Clausius-Clapeyron Equation." the Clausius-Clapeyron Equation defines the conditions under which two phases of a substance (for instance, a liquid and its vapor, or solid ice and liquid water) can coexist in equilibrium. It is not a subject that is routinely taught in introductory chemistry courses. (edit)

During the opening scene, when the nerds are listening through their ceiling with a stethascope, the theme song from the X-Files is playing in the background. The X-Files was a popular Fox tv show about a pair of FBI agents investigating paranormal activity. (edit) Episode title: Goodbye, and Good Luck.

Goodbye and Good Luck is an allusion to the 2005 movie Good Night, and Good Luck is a George Clooney movie telling the history of Edward R. Murrow, who used to close his shows with those words. Clooney also directed the movie. (edit)
