Strangeness of the Future

In tonight's episode, Donna and Reptily occupy adjoining cells at the Preservation Society HQ in Dubbabhera. They whisper at an ancient glory hole through the decomposing granite.

DONNA: "A moment ago I thought I heard an owl shriek in the airspace between the Twin Chanks but it was the echo of my own gut whistle-farting, internally."
REPTILY: "If you can throw your voice that far maybe you can get us the F outta here that far."
DONNA: "You the one knows howda fly."
REPTILY: "It's not an item you know, it's a function you do."
DONNA: "Do your wings of light feel more like extra arms or an active back pack?"
REPTILY: "I am a jellyfish or spanish-shawl nudibranch who moves along only as a secondary result of breathing in and out, at one with the proverbial seawater."
DONNA: "And you're a salty bitch."
REPTILY: "You need to stop coming on to me just to pique my bristles; if I try to tear down this wall, I'll only skin my Epicel, and that makes less with which to fondle you."
DONNA: "Sea Bitch, does it ever seem that you're walking in a future that for you it's not meant? Where everything's a skosh off?"
REPTILY: "Like the light now, anemic egg yolk, music that impersonates a past, and the shriveled clueless recent gawking generation?"
DONNA: "Thasright, darling."
REPTILY: "All the time. And that's what I live for. Because I'm changing too."
DONNA: "Changing or disappearing. I mean it could be either. I donno, sometimes I... Tilly?"
