The Crimson Horror (TV story)

 was the eleventh episode of series 7 of Doctor Who.

It featured the return of Madame Vastra, Jenny Flint and Strax, who were last seen in The Snowmen. It was the 100th episode of Doctor Who since its revival in 2005.

This episode leads directly into the following one, Nightmare in Silver, due to the Maitland children blackmailing Clara to make the Doctor take them on a trip; they found evidence of Clara's time travelling in history books and on the internet.

Synopsis
In 1893, the Eleventh Doctor's old friends, Vastra, Jenny Flint and Strax find an optogram of the Doctor on a victim of the mysterious "crimson horror". They head for Yorkshire, where Jenny infiltrates Mrs Winifred Gillyflower's community of Sweetville to find what has happened to him.

Plot
Madame Vastra and her partners, Jenny and Strax, investigate "the Crimson Horror" — a mysterious condition leaving victims with red skin and preserved like statues — after discovering that one victim has the image of the Eleventh Doctor visible in one of his eyes.

Investigations lead them to Sweetville, an idyllic community run by Mrs Winifred Gillyflower and her never-seen "silent partner", Mr Sweet, apparently as a home for the chosen few to help them survive "the coming apocalypse". Jenny goes undercover as a convert and infiltrates Sweetville, where she discovers the Doctor, chained up in a cell, but only partially preserved; the process didn't work because he was not human. Gillyflower tends to dispose of such "rejects", but he has been saved by her blind daughter, Ada Gillyflower, who has become infatuated with him and describes him as "my monster".

The Doctor is able to reverse the process on himself and he and Jenny go off in search of companion Clara Oswald, who has also been preserved. This confuses Jenny, as she saw Clara killed by the ice woman months earlier. The Doctor tells Jenny that he and Clara were actually aiming to visit London in 1893, but they instead arrived in Yorkshire. They immediately got involved in the investigation of Sweetville and the red bodies piling up in the sewers. The Doctor and Clara, posing as a married couple, joined the Sweetville community to investigate, but Mrs Gillyflower imprisoned and preserved them. The process worked on Clara, but not the Doctor; Ada locked him away, keeping him as her "special monster".

The preservation process on Clara is successfully reversed, and Madame Vastra says the substance used to create the "Crimson Horror" effect is the poison of the red leech, a parasite the Silurians considered a major threat 65 million years ago. The Doctor and Clara confront Mrs Gillyflower, who explains her plan and reveals that Mr Sweet is, in fact, a red leech who has attached himself to her chest. Their plan is to launch a rocket into the skies over England and spread the leech's poison over the planet. Ada, listening in, learns of her mother's plans and confronts her; meanwhile, Clara disables the rocket launch controls.

Holding a gun to her daughter's head, Gillyflower retreats into the rocket silo to activate a secondary launch control; she launches the rocket, but learns moments later that Vastra and Jenny have removed the poison payload. She fires at the Doctor but misses. Strax, who has climbed the chimney from the outside, returns fire, causing Winifred Gillyflower to plummet to her death at the bottom of the silo.

As the old woman lays dying, Mr Sweet abandons his host. Ada shares final words with her mother before brutally killing the parasite with her cane.

Later, the Doctor returns Clara to her 21st century home, where she discovers that the two children she helps care for, Angie and Artie Maitland, have found images of her and the Doctor in different points of time — including a nuclear submarine in 1983 and a manor house in 1974. They have found an image Clara does not recognise; it was taken in Victorian London — but she's only been to Victorian Yorkshire. The children threaten to inform their father that their nanny is a time traveller unless she takes them on a trip in her time machine.

 * Upon returning from her adventure, Clara picks up a toy robot from the Transformers line, specifically a Galvatron figure.

Foods and beverages

 * Several foods are mentioned, including: Amontillado, Pontefract cakes, tea and seed cakes. (Upon being offered Amontillado by Mrs Gillyflower, the Doctor's response is "No, we've had enough of that!", referencing Edgar Allan Poe's short story "", where a character is chained up in a cell.)

Story notes

 * This story marks the first time in the revived series that a companion's associates have successfully deduced the person's time-travelling affairs with the Doctor's on their own, along with the Doctor's ability to time-travel, without questioning the Doctor directly or getting a firsthand experience of the TARDIS. Artie and Angie Maitland discovered pictures of Clara's travels from TV: Cold War, Hide, and a picture of Clara during her Victorian life (TV: The Snowmen) on the Internet, which exposed her secret.
 * Likewise to the above, Clara sees herself in a past life for the first time by looking at the Victorian era photo of herself in London (TV: The Snowmen), cluing her in that she really has lived more than one life, which the Doctor confronted her over in their last adventure, but she later forgot due to the day being rewritten. (TV: Journey to the Centre of the TARDIS).
 * The Doctor is generally much friendlier to Clara, now that he knows she doesn't have control over her multiple lives. He stops treating her like a ghost and treats her as his companion.
 * Although Jenny and Vastra both question the Doctor concerning how Clara is alive, he neither explains anything to them nor is she ever present for these questions. Thus despite having met, Vastra and Jenny do not know that this is a different person and not the same one revived in some manner and Clara gains no knowledge of her past life from the pair.
 * This story is the only television episode featuring Vastra, Jenny, and Strax that was not written by Steven Moffat.
 * This story marked the 100th Doctor Who episode since the programme's revival in 2005.
 * Filming for this episode began on 2 July 2012.
 * Diana Rigg is credited as "Dame Diana Rigg," the first time such an honorific has been included in a Doctor Who screen credit, by contrast, Sir Michael Gambon was not identified as such in TV: A Christmas Carol.
 * This is the second episode in a row to feature a form of family abuse.
 * This is the second Victorian episode in a row to feature a knighted actor as the main villain after Sir Ian McKellen provided the voice of the Great Intelligence in TV: The Snowmen.
 * This episode contains the televised DWU's first surviving glimpse of a guinea, since The Highlanders is lost.
 * Sweetville is based on the real-world model village of, founded in 1851 by wool industrialist Titus Salt. Titus also had a daughter called Ada, after whom a street in the village is named. Sweetville's name may also reflect the model village of whose name was later used for a brand of sweet, a chocolate bar.
 * Vastra's client continually faints when exposed to any unexpected or shocking events. This is a satire of how women were culturally perceived to act in the Victorian era.
 * This story contains no extra-terrestrial elements outside of the Doctor, the TARDIS, and Strax.
 * As Mrs Gillyflower launches the rocket, she sings the line "I'll labour night and day to be a pilgrim." This is from Percy Dearmer's version of John Bunyan's hymn, 'To Be a Pilgrim' or 'He who would valiant be'. Furthermore, Mrs Gillyflower sings it to the melody 'Monks Gate', to which the words were set by composer Ralph Vaughan Williams.

Production errors

 * Vastra's veil is far more transparent than it was apparently meant to be, given the reactions to the revelation of her non-human appearance.
 * The image of the Doctor's face in the dead man's eye at the beginning of the episode is different from when it was shown in the flashback.
 * One of Mrs Gillyflower's "Pretty maids all in a row" in the flashback scene blinks.
 * As Mrs Gillyflower is threatening to shoot the Doctor, Clara, Vastra, and Jenny, Strax appears on top of the tower and fires a shot that causes her to fall to her death, however, a moment after she lands, he is right next to the others.

Continuity

 * The Doctor mentions that the TARDIS used to be worse about landing at its intended destination, saying that he once spent a "long time trying to get a gobby Australian to Heathrow Airport", referencing his fifth incarnation's repeatedly unsuccessful attempts to return Tegan Jovanka to her own time. (TV: Four to Doomsday, et al.)
 * Just after referencing Tegan, the Doctor uses his fifth incarnation's often-used phrase "Brave Heart..." to Clara. (TV: Earthshock, et al.)
 * To go undercover, the Doctor once again uses the alias John Smith. (TV: Spearhead from Space, et. al.)
 * The Doctor does a Northern accent again. (TV: The Rebel Flesh) His ninth incarnation naturally spoke with a Northern accent. (TV: Rose et al.) Clara also briefly speaks with a Northern accent when they are touring Sweetville.
 * Angie has pictures on her laptop of Clara in the 1980s (TV: Cold War), 1970s (TV: Hide), and Victorian London. (TV: The Snowmen)
 * Clara expresses particular surprise at the last picture, as Clara herself had not been in Victorian London. This is because the photo is of her echo, Clara Oswin Oswald. (TV: The Snowmen)


 * The Doctor is once again aided by Madame Vastra, Jenny Flint and Strax. (TV: A Good Man Goes to War, The Snowmen)
 * Strax chants the Sontaran battle cry, "Sontar-ha!" when he attacks the brainwashed humans surrounding the Doctor and Jenny. (TV: The Sontaran Stratagem / The Poison Sky, et al.)
 * The superstition of an eye retaining the last image it sees was previously referenced by the Fourth Doctor, who then used a similar process to read the last images recorded in the brain of a deceased Wirrn. (TV: The Ark in Space)
 * Strax refers to Jenny as a "fleshy boy," showing he still has issues with differentiating genders. (TV: The Snowmen, The Battle of Demon's Run: Two Days Later)
 * Gillyflower says "you do keep turning up like a bad penny young man". Melissa Heart tried calling the Doctor a bad penny, but said "Bad Wolf" instead. (PROSE: The Clockwise Man) The Doctor previously claimed that "Bad Penny" was his middle name. (TV: The God Complex)
 * Gillyflower has an organ that turns around to reveal the launch mechanism for her rocket when specific keys and buttons are pushed. The Tenth Doctor played an organ to stop Lazarus. (TV: The Lazarus Experiment). The TARDIS turned into an organ, which the Sixth Doctor briefly played too. (TV: Attack of the Cybermen)
 * As the Doctor and Clara prepare to leave Yorkshire, Clara says she's had enough of Victorian values. The Doctor previously spoke to Strax about Victorian values, where after a person finds something brand new in the world that they've never seen, they will next look for a way to make a profit from it. (TV: The Snowmen)
 * Strax expresses fondness for grenades, elaborate violent tactics, and acid traps again. He once thought a grenade was the next thing to look for upon finding something new according to Victorian values instead of profit before the Doctor corrected him. (TV: The Snowmen)
 * Jenny mentions the death of Clara Oswin Oswald at the hands of the ice woman. (TV: The Snowmen)
 * Angie and Artie recognise the Doctor, thus connecting Clara to the old images due to him having taken messages from them to give Clara when she was unconscious. (TV: The Bells of Saint John)
 * Angie and Artie find evidence of the Doctor on the internet. Both Clive and Mickey Smith had been able to do research on the Ninth Doctor, claiming he showed up deep in history books and the Internet. (TV: Rose, Aliens of London)
 * Upon being restored to normal, the Doctor kisses Jenny and she slaps him. (TV: The Snowmen)
