Most notably, in this episode, saving Bill robs the Doctor of his sight, rendering the Twelfth Doctor, potentially, permanently blind.

This shows the risks he often places himself in, in order to save his friends, but also the danger in which he might be leaving Earth, should he not return, alive and in good health. Oxygen represents a tipping point in the St Luke's vault arc, as the Doctor finally faces the consequences of not having taken his vow seriously.

Nardole joins the Doctor and Bill on this adventure, for the first time since The Pilot.

Synopsis

The Twelfth Doctor, Bill and Nardole investigate a strange space station, but are interrupted by walking dead in spacesuits... will they make it out alive? And how much does air actually cost?

Plot

The Doctor, Bill and an angry Nardole travel in the TARDIS to follow a distress call to a deep-space mining station. When the TARDIS is jettisoned by the station's computers, the trio are forced to wear "smartsuits", robotic spacesuits capable of independent operation tied to the station. The suits are also the only source of oxygen, as the mining company does not provide an oxygen atmosphere inside the station, and every activity is measured in breaths. The surviving crew warn them that some suits have received instructions to "deactivate" their "organic components", killing the wearer via an electrical discharge but remaining autonomous. This signal can be carried by touch, which has caused most of the crew to be turned into zombies, enslaved to the suits' programming. The Doctor and the others plan to walk outside the station to an uncompleted portion not updated in the computer systems to hide. Bill's suit malfunctions during depressurisation and forces her to remove her helmet. To save her, the Doctor gives her his helmet as they spacewalk. He survives the vacuum of space, but has gone blind from the ordeal.

The computer discovers their location, but as they flee, Bill's suit again malfunctions and will not move. The Doctor leaves her behind, assuring her she will not die. She is, however, electrocuted when they touch her. The Doctor reveals the limit of breaths is an algorithm to stop people "wasting" oxygen, part of the company's automated profit-making system; killing the wearers was just the logical endpoint of corporate profit over human life. He hacks the station's systems to cause the station to self-destruct if they are killed, and convinces the others this is a "good death" and revenge against the corporation. The computers recognise this threat and recalculates the suits' programming, and the zombies turn over their oxygen supplies to the survivors. The Doctor then revives Bill, knowing that her malfunctioning suit did not have enough power to lethally shock her.

The TARDIS is recovered, and they drop the survivors off at their head office to confront the company; the Doctor notes there was a successful rebellion six months later. Nardole restores the Doctor's eyes, but when they return to the university and Bill departs, the Doctor reveals that he "can't look at anything ever again. I'm still blind".

References

Physics

• The Doctor gives a lecture about space, while the audience was expecting a lecture about crop rotation.
  • He describes how one dies when exposed to the vacuum of space.

Chemistry

• The boiling point of water is much lower in a vacuum.
• Electrolysis is splitting water into hydrogen and oxygen. Nardole assumes this is the Doctor's plan, to produce more oxygen which would last 5 minutes.

Biology

• Nardole mentions that he hasn't seen his true face for years. Swapped it for his current one on the run.
• The Doctor intentionally "maxes out" his companions' adrenaline: "Fear keeps you fast. Fast is good."
  • Fear also causes an acceleration in breathing, though, which would constitute a waste of oxygen credits while on Chasm Forge.
• When the suits kill the crew, they deactivate the organic component and disable the central nervous system.
• Bill wonders what happens if she were to throw up in the space helmet.
• After having been exposed to the vacuum of space, Bill suffers from oxygen deprivation.
• The Doctor says he has spare eyes in the TARDIS, though they're from lizards.

Technology

• The space helmets experience an error on the Radio Com Channel.
• The Doctor calls distress calls "[his] theme tune", and emphasises that "You only see the true face of the universe when it's asking for your help."
• Chasm Forge uses artificial gravity.
• The Doctor is happy that the "space doors", as Nardole calls them, are of a classic design. They have pressure seals and hinges. He and Nardole disagree on whether space doors should go "shk shk" or "nnnnn".
• The smartsuits employed at Chasm Forge uses gyro stabilisers, magnetic boots and gloves, and has on-board computers. According to the Doctor, it can run, jump and update one's Facebook. They also have force fields to keep the air in, and oxygen tanks for air supply.
  • A magnetic glove on one of the active suits destroys the Doctor's sonic screwdriver, though the sonic also fries the suit.
  • The suits' AI have "limited problem solving".
• The Smartsuits have unfolding helmets.
• To send the distress call, the miners boosted a smartsuit through the dish.
• Nardole relates the smartsuits' nav system to "when your satnav doesn't know a new road".
• The Smartsuits uses a Powercell to get into the Power Core.
• The Doctor hacks into the Coolant System.

Medicine

• The Doctor claims he has "stuff in [the TARDIS] that'll cure anything".

TARDIS

• The Doctor once told Nardole that the TARDIS can't go anywhere without the fluid link K57. However, he reveals this to be untrue (or, at least, no longer true).
• The air shell room in the TARDIS can provide oxygen to enough of the space station for them to stroll around.
• The Doctor is familiar enough with the layout of the console room that, despite apparently being blind, he is able to hide this and control the TARDIS as though he still had sight, including, it is implied, accurately piloting her both to Ganymede's head office and back to the university.

Travelling

• The Doctor compares going to outer space to camping, and refers to tents and campsites.
• Bill asks if there are reviews for space locations, like there are online for restaurants.

Units of measurement

• Distance is measured in average breaths, rather than in metres.

Locations

• The Doctor sent Nardole to Birmingham for a packet of crisps.
• Chasm Forge is a mining station in outer space. It has a crew of 40.
  • The TARDIS crew gets trapped in the repair station.
• The surviving workers ask the Doctor to drop them off at head office.

Business and economics

• The smartsuits are made by Ganymede Systems.
• Ganymede provides oxygen for personal use only, charging credits for air, and making breathing into a capitalist endeavour. Unauthorised oxygen is automatically expelled, to protect market value.
• The Doctor sees the endpoint of capitalism as "a bottom line where human life has no value at all".
• According to the psychic paper, TARDIS crew is from the Union.
• He remarks that, "like every worker everywhere, we're fighting the suits."

Currency

• The Chasm Forge crew has to pay oxygen credits to stay alive.

Resources

• Chasm Forge is a station for mining copper ore.
• The managers of Chasm Forge are seeking a bottom line for oxygen usage, and are seemingly prepared to kill off and replace workers if they're using too much of it.

Foods and beverages

• The Doctor says that in five whole minutes, "we could boil the hell out of an egg."
• Bill mentions lasagna when giving examples of what a restaurant review is.
• The Doctor sent Nardole out for crisps.
• The Doctor tells Dahh-Ren he sent him out for a latté.
• The Doctor says the phrase "the universe is your crustacean".

People

• Nardole recognises Bill's smartsuit's interface voice as his ex Velma, and remembers her as a "nice girl, actress. Bit orange, left me for an AI at a call centre."
• As a result of saving Bill from dying through exposure to the vacuum, the Doctor has now become blind. An attempt to return his vision was made, but only the colour in his eyes returned.

Time Lords

• Time Lords can survive in the vacuum of space longer than humans can. In the Doctor's case here, he survived but lost his sight.

Literature

• The Doctor says, "Death, where is thy sting?", quoting the First Epistle to the Corinthians in the New Testament.
• Bill reads a book called Leonardo, on Leonardo da Vinci. This book has the image of the Mona Lisa on its back cover.

Culture

• The Doctor makes use of a fun fact.^{[statement unclear]}
• The Doctor mentions, amongst other things the smartsuits can do, updating Facebook.
• Dahh-Ren cannot understand why Bill would experience racism herself. He suspects her to be racist because of her reactions to his blue skin.
  • Nardole says that "some of my best friends are bluish".
• The Doctor insinuates that the purpose of jokes, in general, is to distract people from whatever's about to kill them.
• The Doctor jokes that "too many rescue ships" is a "first-world problem".
• The Doctor quips that he thought he was just tweeting, rather than locking the crew out of the subroutine.
• Bill wonders whether the (missing) man in the working suit has "his tunes on", when he doesn't respond.

Story notes

File:Jamie Mathieson, Mimi Ndiweni & Kieran Bew - The Aftershow - Doctor Who The Fan Show File:Series 10 Teaser - Doctor Who - BBC

• Two scenes of the blind Doctor were featured in an early teaser shown at the end of The Return of Doctor Mysterio, except his eyes weren't cloudy in order to not to spoil this plot point.
• On The Fan Show, Jamie Mathieson worried that this episode would turn out "too political", due to its blatant anti-capitalist themes.
• The read-through for Oxygen took place on 12 October 2016 (immediately after Capaldi and Mackie returned from promoting series 10 at the 2016 New York Comic Con and in Toronto, Ont.), and filming on the episode took place between 17 October and 18 November.
• This is the first time since TV: Face the Raven (TV story) that the Twelfth Doctor wears his navy blue Crombie coat seen in most of the past two series.

Cast

• Three out of the five guest actors, this episode, had previously voiced roles in Big Finish Doctor Who or Bernice Summerfield. Namely, Kieran Bew was in The Lady of Mercia and The Helm of Awe, Peter Caulfield was in Cold Fusion, and Mimi Ndiweni was in Big Dig.
• On The Fan Show, Jamie Mathieson said that an ongoing joke on set was calling Peter Caulfield "Blue Peter", due to his character being blue. This was a reference to Blue Peter.

Allusions

• Two references to Star Trek are made:
  • The Doctor makes a speech about space being "the final frontier", quoting the monologue that opens each episode of Star Trek: The Original Series and Star Trek: The Next Generation.
  • Nardole mentions the "Swish Swish" sound the doors always make. The Doctor says he hates that noise.
• While standing with Dahh-Ren, Nardole states that some of his best friends are "bluish". This joke, of calling a blue person "bluish" as if it is their race, was first seen in the 1969 Beatles animated film The Yellow Submarine, where it was used by a Blue Meanie in an attempt to identify if the Beatles were a member of their ranks. The original use was meant as a satire of the then-common phrase "you don't look Jewish", but it was not intended to be derogatory.
