This is how Opening, Chase explains to Mac and Blaize, and Perry's announcement goes in Llama Drama.
[The episode opens in the lab as Mac and Blaize look at a jar]
Mac Grimborn: Huh. Wonder what's in this jar?
Blaize Skysong: I don't see anything.
Hunter: Not toothpicks, that's for sure. Trust me, guys, I don't wanna know what Adam flosses with.
Adam Davenport: You really don't.
Chase Davenport: [grabs the jar from Mac] Careful! There's metallic nanobots in there.
Blaize Skysong: Then how come we can't see them?
Chase Davenport: Because they're microscopically small.
Mac Grimborn: Um, yeah. The thing is, Adam's made short jokes about R2. Apparently, he's microscopically small and we can still see him.
[R2 shocks Adam]
Adam Davenport: Ow! That really hurt.
Chase Davenport: Nanobots are so tiny, they're invisible to the human eye. I'll show you. Let me adjust your helmet.
[He adjusts Mac's helmet as he sees the nanobots]
Mac Grimborn: Whoa.
[Blaize puts on some goggles and sees them as well]
Blaize Skysong: Wow. So, what do these nanobots do?
Chase Davenport: They function like mini-doctors inside the human body. When patients swallow them, they'll seek and destroy any diseased cells or foreign matter.
Adam Davenport: All I've got is a statue of liberty somewhere in my gut. Time to swallow a search party.
Mac Grimborn: No, Adam! [does tug of war with Adam]
Crosshair: Come on, Wrecker, we don't wanna step on broken glass.
Wrecker: What broken glass?
[Adam drops the jar as it breaks]
Echo and Tech: That broken glass.
Wrecker: Right. Let's go, fellas.
[The others leave as the nanobots get everywhere]
Adam Davenport: Whoa, look at them go!
Mac Grimborn: If we lose these, Donald's gonna kill us! Great. Once again, we have to clean up Adam's mess.
Adam Davenport: Hey, dude, I got this. I'll just grab a paper towel and pick em up. [walks across the nanobots]
Mac, Blaize and Chase: Adam!
Adam Davenport: Yeah, you're right. Better get the vacuum instead. [walks back across the nanobots again]
Blaize Skysong: No, Adam, stop!
Adam Davenport: I hear ya. Better grab the mop. [walks across the nanobots again]
[The scene changes to Mission Creek High as everyone sees Dewey Dingo]
Blaize Skysong: Uh, guys, why is Dewey the Dingo standing in front of the hallway?
Adam Davenport: Uh, I don't know, but I think it means we get six more weeks of winter.
[The spotlights turn on as we hear Perry's voice]
Terry Perry: [offscreen] Ladies and gentlemen, introducing the principal, a four-foot-eleven spitfire from Portland, Maine. Terry Perry!
[Perry appears and throws Mac her bandanna]
Mac Grimborn: Principal Perry, what are you doing?
Terry Perry: Just thought I'd spice up the morning announcements. Takes me back to my days of playing semi-pro ball in Romania. Here ya go, kid. Souvenir. [tosses her sweat band to a student] I'm sure you're all wondering why Dewey the Dingo is here. Every year before the big homecoming game against the Deerfield High Leapin' Llamas, some punk manages to steal Dewey. No matter where I put it, they always find a way to get it.
Mac Grimborn: Well, try wearing it. That'll keep people away.
[Blaize snickers]
Terry Perry: Do you really wanna go there, Shiny Black Gold? Anywho, to make certain they don't take him this year, I'm assigning round-the-clock shifts.
[A student hands her clipboard and she gives it to Chase]
Terry Perry: Right. I'm gonna go hit the hot tub. Heard a couple things pop when I ran out here.
Blaize Skysong: Oh, great. Three man and one dragon shifts and she paired us with Adam!
Adam Davenport: Great. So we got two men. Who's the other one?
Mac Grimborn: Chase.
Adam Davenport: Oh. So, who's the dragon?
Blaize Skysong: It's me.
Mac Grimborn: This is another reason why I like to think Chase might be smarter than Adam.
[Blaize nods]
