Wild Blue Yonder (TV story)

Wild Blue Yonder was the second of the three 2023 specials of Doctor Who, broadcast on 2 December 2023 as part of the 60th anniversary celebrations.

The Fourteenth Doctor talks about the Flux, with it being confirmed what the lasting damage to the universe was; 50% of the universe was destroyed, meaning only 25% of what the universe was in 1981 still exists, as the Master previously accidentally destroyed 25% (which included the Traken Union) with Entropy by closing off the Charged Vacuum Emboitements to E-Space (TV: Logopolis).

Synopsis
The TARDIS, out of control, abandons the Doctor and Donna on a faraway, mysterious spaceship, with deadly secrets in every corner.

Plot
The Doctor and Donna crash the TARDIS in an apple tree in 1666 right as Isaac Newton was reaching his famous epiphany. They ask him what year it is, and from his answer figure out his identity. Donna is delighted in spite of the fact that that TARDIS is going haywire. She insists on making a joke about the gravity of the situation her and the Doctor find themselves in as they depart. Newton, still thinking about his epiphany, reflects on these last few words, trying to recall them. For his new discovery he has a name - "mavity".

The TARDIS then lands in an unknown spaceship, heavily damaged. The Doctor places his sonic screwdriver into the latch in order to prime the TARDIS to regenerate, to heal itself from the damage it's sustained. They take a look around the ship before hearing the TARDIS dematerializing as a result of the Hostile Action Displacement System. At first the two of them despair, but the Doctor explains to Donna that if they resolve whatever hostile action they've encountered there's a good chance the TARDIS will return to them. The two set off into the ship with renewed determination, marching down a long corridor. As they walk, the environment shifts around them and a loudspeaker blares "fenslaw". Neither of the two knows what this means - the TARDIS translates but has left, and the Doctor doesn't speak this language.

The two come across a small hovercraft and a slow moving robot, marching down the hallway. The pair find their way to a cockpit and try to decipher what they can from the ship's computer. There are no life signs on board, and the airlock had been opened once three years ago. The Doctor realises that the ship is one that had fallen through a wormhole and ended up on the edge of the universe, 100 trillion lightyears from everything else - not even starlight has yet propagated long enough to reach them.

The intercom blares "coliss" and the ship shifts again. The two wander into a room filled with drawers of baseplate repetition filaments. The Doctor asks Donna to move all the ones in a lower drawer to to a higher one - the ship is on idle and needs to be powered back up. The Doctor finds another room with a spindle and works on adjusting it. As Donna moves the plates it grows colder, which she murmurs about. The Doctor acknowledges the change in temperature to her. And as the two talk the Doctor occasionally mumbles about his arms being too long.

The Doctor is still back in the room with the spindle and is still working on adjusting it as it grows cold and Donna enters. He's surprised at how fast Donna was. The two chat, and Donna mentions that her arms are too long. The Doctor turns to look at her and sees her arm to be stretched beyond all proportion, realizing that this isn't Donna.

Both the Doctor and Donna from the two rooms run back to each other, with their doppelgängers slowly following behind. They claim to have come from nothing, to be Not-Things. They chase the Doctor and Donna, who use the hovercraft to try and outpace them, but the Not-Things grow and twist in size, keeping pace, before eventually tangling together and blocking each other and the whole of the corridor, slowly beginning to untangle.

They climb upwards to a vent but as the intercom blares "brate" and the environment shifts they become separated. The two walk around separately, trying to find the other, and two pairs of Doctors and Donnas unite. The four try to convince their partners that they're real, through conversation or other means. But each of the Not-Things make mistakes as they're about to convince the others. The Doctor and Donna flee again, the intercom blaring "gilvane".

The four find themselves together in a room, and the Doctor and Donna figure out which of them is real by knowing enough about how the other acts. As the Not-Things begin to advance, the Doctor lays down a line of salt, insisting that they can't cross it without counting every grain. At first the two are dismissive, saying it's a superstition. But the Doctor insists, it's a superstition, and it's real, both at once. The Donna Not-Thing bends down and begins to count as they interrogate the Doctor Not-Thing, who they notice is slowly acclimatizing. The Not-Thing explains that they have heard the "noisy, boiling universe", and wish to venture there to play the games those in the universe do, that have given shape to the Not-Things. The Donna Not-Thing blows away the salt, and the duo advances as the intercom blares "stond".

The Doctor and Donna run back to the cockpit and lock themselves in, the Not-Things standing outside, slowly copying them more and more as the pair stresses and thinks. In order to combat this they try to think as little as possible, but find themselves unable to do so - the ship just has so many questions. They manage to find the captain of the ship circling the ship having killed themselves, and the Not-Things don't know why - they need to know why.

The intercom blares "ratico" as the Doctor explains that the captain killed themselves to stop the Not-Things from fully copying them, from knowing what she did to stop the duo from reaching the rest of the universe, slowly, so slowly that the duo could never know what it was. The ship is slowly reconfiguring into a bomb, the words being a countdown. "Vandeen." All four run after the robot, the trigger walking slowly towards the final button, the Doctor speeding up the countdown to prevent the Not-Things from stopping the self-destruct. "Blinss." The four scrap as they run towards the robot, the Donna Not-Thing trying to keep the pair away as the Doctor Not-Thing races towards the robot to stop it. "Sensill" As the Doctor Not-Thing gives up on trying to copy the Doctor and becomes quadrupedal in order to out speed the pair, the Doctor realizes that as the hostile action is resolved, the TARDIS should know, and the TARDIS begins to rematerialize. "One." He tries to determine which Donna is real, and pulls in the one that answers his questions to his satisfaction.

As he leaves, the other Donna cries, insisting that he got the wrong one, that she's real. "Tacsladia." The robot pushes the button and the explosion begins, rushing to meet her. On the TARDIS, the Doctor turns to face the Donna on board, having scanned her - her arms are ever so slightly too long. He ejects her and Donna rushes in, the pair hugging as the TARDIS dematerializes, flying away from the exploding ship. As they travel back to London, reflecting on their adventure, the Doctor ponders as to whether it was a good idea to use the salt, a superstition on the edge of the universe, where the walls are thin.

The Doctor and Donna land the TARDIS, back near the alley from which they took off in London — a day or two off, according to the Doctor. As they exit they find Wilfred Mott who says that he's never lost faith, the Doctor would come back to save them. As they look around, small explosions and riots break out, and a plane crash lands not far away. Wilf is emphatic, the entire world is coming to an end and the Doctor needs to save them.
