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.

Synopsis
The TARDIS takes the Doctor and Donna on a journey to a faraway, mysterious place and abandons them in the middle of Hostile Action.

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 promulgated a distance great 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 want to play the games those in the universe do, that they've 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 find the captain of the ship, who killed herself previously in order to feel a maximum sense of adrenaline. The Doctor realises (at the same time as the creatures) that the ship is slowly counting down to an explosion. Now they know, all four run after the robot Jimbo - the Doctor and Donna to let it explode the ship; the creatures to stop the explosion from occurring.

The robot presses a red button and explodes the ship. The TARDIS materialises as a result of the Hostile Action having been entirely displaced and the Doctor runs aboard. Kicking on the ground to gain momentum, he rushes towards the two Donnas, who each claim to be the real one. He ascertains which is real and takes her aboard, leaving the other to die, who complains of her fate.

The Doctor then rematerialises the TARDIS near this real Donna, throwing the fake one out, just in time to save her and leave as the ship explodes.

After a chat in the console room, the Doctor and Donna emerge from the TARDIS, back near the alley from which they took off at the end of the previous episode. Wilfred Mott is there to greet them, sitting in a wheelchair. It turns out that there is some unknown offensive action occurring in the scene, with people fighting and bashing away - what caused this and how can the Doctor and Donna put it right?
