The Night of the Doctor (TV story)

 was a mini-episode released just prior to the 50th anniversary special. It starred Paul McGann as the Eighth Doctor, in his first on-screen appearance since the 1996 tele-movie. It also featured his regeneration — meaning that McGann has uniquely appeared on television only in regeneration stories. Initially uploaded to the BBC's YouTube channel on 14 November 2013, the "mini-sode" was subsequently made available to UK viewers on BBC Red Button beginning on Saturday 16 November at several times throughout the week until 23 November.

Synopsis
Still trying to skirt around the edges of the Last Great Time War, the Eighth Doctor is forced to fully join the conflict by the mysterious Sisterhood of Karn. Killed while trying to save a woman who hates him for simply being a Time Lord, the Doctor gets to choose what his next incarnation will be like. He opts for a warrior...

Plot
Cass is piloting a damaged spaceship on the verge of crashing. The ship's computer offers to call for a "doctor" upon being asked for support, to which Cass responds that she doesn't need one because she's not injured. Meanwhile, the Doctor's TARDIS is seen catching up to her ship. Inside, Cass continues to tell the ship that she is trying to send a distress call, and doesn't need a doctor when the Eighth Doctor suddenly appears, stating that he is a doctor, but probably not the one she was expecting.

When the Doctor notices that the ship's crew is missing and wonders why Cass is still aboard, she explains that she teleported the crew off the ship and stayed behind. The Doctor then welcomes her aboard, and takes her hand as he leads her to the TARDIS. As he is trying to open the doors to the room where the TARDIS is parked, Cass says she joined the crew to see the universe, and wonders if it is always like this. He finally opens the doors with his sonic screwdriver, revealing the TARDIS, and reassures Cass that it's bigger on the inside. Cass is horrified, and correctly identifying the Police Box to be a TARDIS realises that the Doctor is a Time Lord, a species taking part in the Time War. The Doctor counters that he hasn't participated in the conflict, but this fails to assuage Cass. When he points out that at least he's not a Dalek, she replies that one can hardly tell the difference anymore, and promptly locks herself on the other side of the door. Although The Doctor states that he won't leave the ship without her, Cass replies that she doesn't mind; she would rather die than travel with a Time Lord.

The ship crashes on the planet Karn, where the Sisterhood of Karn have been expecting the Doctor. Finding his dead body in the wreckage, they are able to revive him, albeit briefly. As he regains consciousness, the woman named Ohila tells him he has four minutes to live, and that her cult has several potions which can begin, and influence, a Time Lord's regeneration process. The Doctor soon comes to recognise the Cult as the Sisterhood of Karn, which Ohila confirms, claiming that Time Lord science is "elevated" on Karn, and the various potions will allow him to determine the nature of his next incarnation.

When asked Ohila tells the Doctor that the Sisterhood is helping him as he is the only hope to stop the Time War which threatens all of reality, but The Doctor still resists the idea of fighting. Responding to this she states that since he is a doctor he should attend his patient, prompting members of the Sisterhood to bring in Cass, who is beyond even the Sisterhood's healing powers. When the Doctor grieves that she wanted to see the universe, Ohila claims that she didn't miss much, and that he is part of the Time War already, "like it or not." He says he would rather die than join the Time War, prompting Ohila to remind him that he is already dead, and ask "how many more" will he let die.

Succumbing to their persuasion, and begging, the Doctor removes a bandolier from Cass' body and tells them to, "make me a warrior now". Ohila offers one of the drinks which she developed herself, which the Doctor takes, and yells at the Sisterhood to get out. As they leave, he asks if it will hurt? Ohila simply replies "Yes", the answer The Doctor wanted. He salutes his eighth incarnation's companions and friends and apologises to Cass, drinks the potion, and begins to regenerate. Ohila wonders if it has worked when the process is complete. A figure gets to his feet and buckles on Cass' bandolier, as if girding himself for battle.

As the words "Doctor no more" are heard, we see a reflection of the younger version of the man the Eleventh Doctor and Clara Oswald encountered in the Doctor's time stream on Trenzalore.

Story notes

 * The day of the Eighth Doctor's return to the screen also marked Paul McGann's 54th birthday.
 * The Eighth Doctor's costume here, designed by Howard Burden, is unique and is based on the Doctor's costume from the TV movie. There's no reason to believe that Burden did anything other than simply re-design the costume. Nevertheless, the costume is highly reminiscent of the character's appearances in Doctor Who Magazine comics, where his costume was slightly different almost every story.  Perhaps the closest matches are found in Doctor Who and the Nightmare Game, where the combination of coat and open-neccked light shirt are prominent, and Uroboros, with its vest, tan pants and open-collared light shirt. Although the leather riding boots are an apparent innovation of this short, they, too, have precedent in the pages of DWM: Bad Blood had him in the Wild West wearing quite similar boots. The costume is notably dissimilar to that seen on the covers of Big Finish's Dark Eyes series, although it doesn't obviously contradict the brief description of that costume given within the narrative of the audio.
 * The Doctor mentions his companions Charley, C'rizz, Lucie, Tamsin and Molly, all from Big Finish audio productions. It was the first time that the television series directly referenced Big Finish characters.
 * The BBC initially promoted this episode with the teaser that the audience would be shown either the Tenth Doctor, Eleventh Doctor, or the new unspecified incarnation. While this was indeed true, as it did feature the unspecified incarnation, it was a red herring to hide the surprise return of Paul McGann as the Eighth Doctor, and to lead into the secondary reveal of the "John Hurt Doctor", called "the War Doctor" by the credits.
 * The only appearance of John Hurt's Doctor is in the form of a reflection using archive footage of a younger John Hurt.
 * This story introduces the idea that the Time Lords had become collectively hated during the Time War by the individuals who had suffered from their actions. The Doctor's conflict with his own people over the issue is also made apparent.
 * The phrase "no more" appeared in the 50th anniversary #SaveTheDay trailer, scrawled onto a girder. The meaning of the phrase was obscure prior to the release of this short, which gave some context for the words in its closing seconds.

Production errors

 * The St John's Ambulance logo is visible on the SFX shot of the TARDIS as it chases after Cass' ship, but isn't there when the practical TARDIS prop is seen.

Continuity

 * The Eighth Doctor's last visit to Karn was in AUDIO: The Vengeance of Morbius.
 * Since making his decision about the war in PROSE: Museum Peace, the Doctor has decided not to fight but help out where he can.
 * The Sisterhood of Karn last appeared onscreen in the Fourth Doctor story TV: The Brain of Morbius.
 * Cass' bandolier is presumably the one that John Hurt's character is wearing in The Name of the Doctor.
