- Fermín de Pablo: And why should I believe you?
- Saúl Pérez Sabán: Maybe because those who look for the truth run the risk of finding it.
- Iván Noiret León: You can't make me testify.
- Jacques Noiret: I'm not making you. I'm asking you.
- Iván Noiret León: Sure. You're asking me to commit a crime.
- Jacques Noiret: It's also a crime to have a stash of ecstasy, and I haven't said a thing. I'm asking for something any kid would do for their father.
- Iván Noiret León: If you say so. It'd be different if I got something out of it.
- Jacques Noiret: What do you want?
- Iván Noiret León: To leave this school.
- Jacques Noiret: Done. Anyway, you're getting expelled.
- Titiritero: In town they say fireflies attract kids into the woods, and those who follow them don't come back to talk about it.
- Roque Sánchez Navas: And if they don't come back, who has told the story?
- [a running gag]
- María Almagro: Iván, we have to talk.
- [Iván rudely ends the conversation]
- María Almagro: [shortly thereafter]
- Carolina Leal Solís: We have to talk.
- Iván Noiret León: You all love talking. I have nothing to talk about with you or anyone.
- [later at the end of class]
- Héctor de la Vega: We have to talk.
- Iván Noiret León: [laughing to himself] I can't believe it.
- [later in the hallway]
- Iván Noiret León: [on phone to father] I can't believe what I'm about to say, but we have to talk.
