Quote #1
RIFF RAFF: It's astounding. Time is fleeting. Madness takes its toll.
"The Time Warp" is the first song inside Frank's castle, and it's when things start to get weird for Brad and Janet. But here, they don't participate in the song; they observe the madness from the outside.
Quote #2
RIFF RAFF: With a bit of a mind flip.
MAGENTA: You're into the time slip.
RIFF RAFF: And nothing can ever be the same.
MAGENTA: You're spaced out on sensation.
RIFF RAFF: Like you're under sedation.
Riff Raff and Magenta address Brad and Janet directly, letting them know that they can't stand to the side and be observers of the craziness. Soon enough, they're going to be a part of it, too.
Quote #3
FRANK: So, come up to the lab, and see what's on the slab. I see you shiver with antici—pation. But maybe the rain is really to blame. So I'll remove the cause, but not the symptom.
Frank knows that, by this point, Brad and Janet are intrigued. They want to know what's going on inside the lab, and they probably wouldn't leave even if they had the opportunity to.
