(We see the SKOOL as the school bell rings and kids pour out of the doors and windows. The camera moves in for a sweep over the heads of the crowd and goes through the door, viewing the SKOOL hallways as a few random kids stop at their lockers. The camera the moves on to the classroom of Ms. Bitters, where Zim sits at a desk at the center of the classroom, looking bored. Ms. Bitters sits at her desk, looking at Zim like a vulture, ever vigilant, with her hands folded on her desk. They both sit staring at each other for a few moments, when Ms. Bitters' phone rings. She picks it up without taking her eyes off of Zim, and puts the phone up to her ear.)
Ms. Bitters: Hello?... What do you mean, his head is stuck?... Does it have to be right now?... Yes, I understand that his safety is important... But I'm in the middle of supervising a detention, you can't just... Yes, I understand... Very well. I'll be there as soon as I can.
(She slams the phone onto the receiver, and the phone goes back into its compartment, the screams of ghosts accenting it's decent. Ms. Bitters looks at Zim.)
Ms. Bitters: Listen, child, I have to go get the Principal's head unstuck from a chair in the cafeteria. Don't think about escaping, because if you do, you'll be destroyed by the security system, just like that frog kid.
(A chord of dramatic music)
(Ms. Bitters pushes a button, and a cage slams down on Zim, effectively trapping him. Red lasers roam the room like searchlights, and spikes emerge from the floor. Ms. Bitters slithers out of the room, leaving Zim alone in the madness. Zim looks slightly frightened of the threatening security system, and touches one gloved hand to his ear.)
Zim: Centipede calling Shadow, come in shadow.
Gaz: Why are you talking in code? I know who you are, Zim.
Zim: Yes, but what if someone hacks into our frequency?
Gaz: So? It's not like this is a very secret mission.
Zim: That is what you think, Dib-sister. If you fail to rescue me from the human Earth prison called detention, then you shall not accompany Zim on the mission to reveal the Dib-Stink.
Gaz: Whatever. I'm just doing this to see my brother get destroyed.
Zim: As you wish, Dib-sister.
Gaz: What do you want me to do, again?
Zim: The Scary Earth-teacher has left the classroom, but there appears to be some form of security preventing Zim from leaving. I need you, Dib-sister, to assist in Zim's escape.
(We see Gaz inside of a ventilation vent, looking through a grate at Zim's head and Cage.)
Gaz: Got it. I'll be right there. Shadow girl, over and out.
(She removes a small pen from her pocket, and removes the cap, revealing the pen to be a small screwdriver. She uses the screwdriver on the screws of the grate, catching them before they fall. She then lifts the grate, sets it down softly on the vent floor, and uses her hands to slide through the opening, past the lasers and through the bars into Zim's cage, landing on his desk in a crouch. This startles Zim so much he falls out of his chair. Gaz holds out her hand to Zim)
Gaz: Get up.
(Zim grabs her hand and she pulls him to a standing position Zim looks at her quizzically.)
Zim: How did you...?
Gaz: Oh, like you haven't broken the laws of nature before.
Zim: Well, you got in, now how do plan to get me out-
(Gaz grabs Zim and throws him back up through the bars of the cage and into the vent, where he bonks himself in the head. Gaz sits in the seat and looks at Zim, motioning for him to get out. Zim's eyes widen, and Gaz nods. He crawls down the vent, getting out of sight just as Ms. Bitters enters the classroom.)
Ms. Bitters: (surprised) Gazlene Membrane?
Gaz: Hello, mother.
