- Douglas Zieglar: The last thing you want, the last thing you ever want is for them to get to you. 'Cause when they grab a hold, they will take your will to live. Everything that made you you is gone. You don't want to talk, you don't want to move. You're a shell.
- Mattie Webber: Just like Josh said, he pulled something through...
- Dexter McCarthy: Pulled ghosts through the Wi-Fi? It just doesn't make any sense.
- Thin Bookish Guy: [adding to their conversation] It makes all the sense in the world. Do you have any idea of the amount of data that's floating out there? The amount of information we just beam into the air? We broadcast to everyone where we are, and we think we're safe? The whole freakin' city is going insane, and we're acting like it's nothing. Well, it's not nothing. It's something we don't understand, and it is coming for us.
- Goth Girl: You're freaking us out, man.
- Thin Bookish Guy: It's the end of the world. That's what it is.
- Goth Girl: Maybe it's the booze in your coffee.
- Professor Cardiff: The pathological mind can only satisfy its need for the other by consuming the other; leading, once again, to great need and, of course, the cycle begins again.
- Mattie Webber: How long have you been watching this?
- Dexter McCarthy: No, I think the question is, how long have they been watching me?
- Dexter McCarthy: I can still shut the system down.
- Mattie Webber: Don't you get it? There's no system to shut down. They are the system.
- Tim Steinberg: It has to be a virus. I mean, his computer is probably still logged on. It's just hitting his address book.
- Mattie Webber: They said, "Help me."
- Stone: Yeah, but viruses always have some important-sounding shit. I mean, just the other day, I got one that said, "Urgent, Stone. Read me now." I mean, that's a natural occurrence. It happens all the time...
- Isabell Fuentes: That was from me, you idiot.
- Stone: Damn. That was pretty strong.
- [last lines]
- Mattie Webber: We can never go back. The cities are theirs. Our lives are different now. The things that were supposed to connect us to each other instead connected us to forces we could never have imagined. The world we know is gone, but the will to live never dies. Not for us... and not for them.
- Dexter McCarthy: It was your friend's computer. Did he get off on the stuff? Was he shooting those videos and selling them online? What was he doing?
- Mattie Webber: Josh tied a phone cord around his neck and hanged himself - that's what he was doing!
- Mattie Webber: [to Dexter] That computer belonged to someone I know. You found his computer. Now you're messing with the people in his address book? That's a really shitty thing to do.
- Mattie Webber: [crying] I don't why I didn't see the signs. I should have been there... done something.
- Dr. Waterson: Sometimes there aren't any signs. This was a very intensely lonely young man... more than you could ever know, he was very skilled at hiding his loneliness. And when he couldn't hide it anymore, He... hid... himself. Have you ever felt that kind of loneliness?
- Stone: [showing off his pirated DVDs] Aw'right, check this out. I got all the new joint... Actually, these last four, y'all have already. And then these five, right here, won't even be out for another month. Plus, I have some other ones here...
- Isabell Fuentes: Yeah. You know, you should just save us a few little tax dollars and drive yourself to jail right now.
- Stone: Can I use your car? And don't forget, I gotta take you with me, because you did buy some of the stuff.
- Dr. Waterson: You can't articulate what you think is going on out there, Mattie, because it isn't real.
