The time between adventures helps with cooling off. She never wants to be fatally reckless again- she's already gotten so many chances, and she's not sure what it would take to break her out of stasis. So she's enjoying herself in one of her TARDIS' more entertaining diversions: a forest, rather similar to one she remembers from an early adventure on Earth. The familiar ache that accompanies those memories is easy to distract herself from with just how alien this one is underneath the surface. Her TARDIS gives her the best presents.
Her latest traveling companion is sitting on the floor of the engine room. His mind is swimming as he tries to understand the schematics he's reading; engineering, science, and math had never interested him before now, but the promise of travel through space and time is enticing enough to draw him in. Like a moth to a flame, or Sisyphus up the hill, he begins.
That's why, he will later insist, that he didn't notice the ship had already landed.
She's busy running for her life. She can't even travel out of this shithole of a world - Fillory, really?? - so she's stuck using her mediocre cardio abilities and she keeps tripping like some sort of B horror movie damsel -
When she spots the diner she kind of - stops and stares at it for a whole three seconds before she runs towards it. It has to be magic, it's in the middle of a random forest in Fillory. Or it's a trap. Whatever. She doesn't have much choice at the moment.
She swings open the door and runs inside.
He knows more than enough to turn the damn thing on. He flips some number of switches, presses a few buttons, and pulls a lever; the engine makes an odd sound as it powers up, but it's clear that it has- and clearer, through the viewscreen, that the diner is de-materializing as they take off.
"This machine has very little to do with 'magicians'. Whatever dimension you're from, those rules no longer apply. Prepare yourself for something so far beyond your paradigms that it will challenge the underpinnings of your reality- on some days. Other days, you meet aliens who seem exactly like humans."
A part of the wall slides aside, revealing a woman in a fur coat, a beaded skirt, and apparently fighting with some kind of nest that's taken up habitation in her hair.
"Sorry, just a moment, I'll be right with you!"
She tromps about the console room, giving the guests a wide berth. The glittering insects bite at her flesh, leaving dark red marks as they go.
"You know, we can go anywhere in time or space, no one is limiting your simple, shallow taste but yourself."
She taps one of the many semispheres on the walls; it glows a fluorescent white for a moment before a small perfume bottle falls out of it into her waiting hands. She sprays the bugs in her hair and they begin to congregate in one spot. She continues spraying.
"Welcome to my T.A.R.D.I.S! Sorry about the mess."
"Oh, this again. He wants your full name, he's some kind of formality enthusiast, I swear. Clara Oswald, at your service. Very formerly of Earth, the United Kingdom, the 2010s, or something thereabouts. I've lost track. Do you have somewhere or somewhen on Earth you've always wanted to go? I like to start there before we move on to bigger and weirder things."
