The TARDIS screeches and spins, tumbling through time and space. The Tenth Doctor pulls levers and switches, twisting gauges and pushing buttons. No such luck. The TARDIS is wrecking and the Doctor is stumbling about trying to fix the damage.
"Donna! Pull the Proxy-Neutron Lever!" The Doctor yells.
"Do you really expect me to know which one that is?" Donna yells through the hiss and bangs of the TARDIS.
"Just that one there" he points to a red and silver handle next to an odd spiky twister button thing.
"This one?" The Doctor nods and Donna pulls the lever, sending the TARDIS pummeling downwards. The Doctor skids to the right a little and presses do-dads, making the TARDIS a healthier sounding time machine. Donna smiles at the Doctor and the Doctor smiles back.
"Right then... we've crashed." Donna frowns and throws her arms up.
"What? I thought you just landed this thing! What do you mean 'we've crashed'?" The Doctor springs to the door.
"I did land her, after we crashed. And if you wouldn't mind Donna, the TARDIS is not a thing. Now then, lets take a look." The Doctor swings the door open, and immediately regrets it. Black smoke pours in making it hard for The Doctor and Donna to breathe. The Doctor slams the TARDIS door shut and faces Donna.
"Well, that was unexpected." The Doctor sprints to the wardrobe and brings back two gas masks. He puts one on and tilts his head to the side. "Are you my mummy?" under his gas mask he smiles. Donna huffs at him.
"The TARDIS sounds fine now, why can't we just leave? Go some place nice. Like Brazil or something." Donna puts the gas mask on anyways, knowing that the Doctor would never turn away from the unknown.
They head outside and pass through a thick layer of black smoke. Once on the other side both the Doctor and Donna turn to look at the TARDIS. Sure enough the TARDIS is the cause of that smoke. The Doctor removes his gas mask, with Donna following his lead, and waves his hand through the smoke wavering it away.
"Aw, this'll take months to repair. What did you pull, Donna?" Donna frowns at him and starts to rebuttal.
"Me? What did I pull? What did you pull. We were drifting nice and easy until you said 'lets go to Jupiter's Ridge or something like that. I didn't press anything!" the Doctor looks at Donna with a serious face.
"Now we're stranded. Time to find out where we are! And when." The Doctor turn to face away from the TARDIS, finding horror beyond anything he's ever seen. He stands facing the planet with a scared look on his face. Donna turn to look at the Doctor, worried he hasn't said anything.
"Where are we?" she says with a curious tone. She gets nothing in return for a couple seconds of unruly silence.
"Doctor, seriously, where are we? Doctor answer me." The Doctor faces Donna.
"Gallifrey."
