Let's Kill Hitler (TV story)

Let's Kill Hitler was the eighth episode in the sixth series of Doctor Who and the first episode in the Autumn half. As with A Good Man Goes to War, it brought revelations about River Song.

Synopsis
In the desperate search for Melody Pond, the TARDIS crash lands in 1930s Berlin, bringing the Doctor face to face with the greatest war criminal in the Universe. And Hitler. The Doctor must teach his adversaries that time travel has responsibilities – and in so doing, learns a harsh lesson in the cruelest warfare of all.

Plot
Amy and Rory drive through a corn field with Amy giving directions badly. They stop in the middle and see the Doctor standing by the TARDIS. He shows them a newspaper: the local paper has a front-page story about crop circles that spell out "Doctor." Rory takes the paper and spots a line in the corn field message that he and Amy did not create. A sports car races up to them, nearly running over the Doctor, and Mels steps out. She knows about the TARDIS and the Doctor from Amy since she grew up with them. She has stolen the car and is followed by the police, so she points a gun at the Doctor and orders him to take her to kill Hitler.

In a flashback, young Amelia Pond and a young Mels talk about the Doctor when young Rory walks in because he has been abandoned in a game of hide and seek. Mels turns out to be a troublemaker in Amy's school, and is often in trouble for making rude remarks to teachers, continually referencing the Doctor, and stealing things. Back in the TARDIS, Mels has shot the control console and the TARDIS is spinning wildly out of control.

In 1938 Berlin, a janitor is watching a Nazi general. The scene cuts to a Star-Trek-like interior with a captain and crew. They speak about copying the Nazi general. The scene cuts to the janitor walking into the general's office. In the futuristic room a woman comes in, complaining about skin tones. She takes an elevator to the eye, where the anti-bot is first heard. She looks through the janitor's eye and relays skin tone information to the control room. The janitor grows taller and becomes the Nazi general's double. The janitor/general sucks the real general into him, where he is killed by the anti-bots. The Tessalecta next approaches Adolf Hitler to kill him but they are too early in his time stream.

The TARDIS crashes into the Tessalecta. The Doctor realises whom he saved. Hitler tries to kill the Tessalecta, but misses and is put in a cupboard. Hitler has shot Mels, who reveals herself to be Melody Pond and regenerates into River Song. The Tessalecta scans Melody and discovers that she will kill the Doctor.

Melody tries to kill the Doctor several times, but he thwarts her. She kisses the Doctor and jumps out of a window to go shopping for clothes after revealing that she has poisoned the Doctor with her lipstick. The Doctor, dying, orders Amy and Rory to catch Melody; this is who she will be if Kovarian keeps her. The pair watch her knock out some Nazis using her regenerative energy, steal their guns and flee on a motorbike.

Amy and Rory follow on a second motorbike, and the Tessalecta on a third. The Doctor climbs into the TARDIS. He asks the TARDIS voice simulator to take the form of someone he likes. The TARDIS chooses Rose Tyler, Martha Jones, and Donna Noble before settling on the young Amelia Pond. After much debate, Amelia reveals that fish fingers and custards will control the pain, but he will still die.

Melody steals all the clothes from people in a restaurant and works on her ensemble. Amy and Rory arrive outside the restaurant, pursued by the Tessalecta, now disguised as Amy. In the restaurant, Melody is trying on outfits when Amy walks in and speaks. She is actually the Tessalecta

Amy and Rory awake inside the Tessalecta, where the antibots attempt to kill them, but they are saved by one of the crew. The Doctor arrives in evening clothes. The Tessalecta starts to torture Melody. The Doctor begs it to stop. Melody is frozen in place. The Doctor asks the Tessalecta for information on himself and Amy persuades them to give the Doctor what he wants. It informs the Doctor that the Silence are behind the plot to kill him. When the Doctor asks what the Silence are, the Tessalecta explains that the Silence are not a species but a religious cult that believes "silence will fall" when the oldest Question in the universe is asked. It does not know what that Question is, however.

The Tessalecta resumes torturing Melody, until Amy turns off all of their security clearance devices, causing the antibodies to attack the crew. Before the antibodies can kill all of them, the crew teleports away. The dying Doctor begs Melody to save Amy and Rory, who are about be killed by the antibodies. The TARDIS materializes around them. Melody has flown the TARDIS, after it taught her how. The trio run to the Doctor but he says there is no way for him to survive. Melody sacrifices her remaining regenerations to revive him, almost killing herself.

The Doctor, Amy and Rory leave Melody in the best hospital in the universe. They must let her find her own way. The Doctor claims that he downloaded some boring information from the Tessalecta. He has discovered the day of his death. River/Melody applies for a degree in Archeology at the Luna University two years before Demons Run.

TARDISes

 * The temporal grace in the TARDIS, which supposedly prevents weapons fire is said, by the Doctor to be a "clever lie".

Ratings
UK Overnight: 6.2 million

Myths

 * The Daily Mirror reported that Rose Tyler, Martha Jones and Donna Noble will appear in this episode. Although an image of each was seen, they were for a TARDIS interface, rather than the characters themselves. These were stock images; the actresses did not record any new scenes.

Filming locations

 * Swansea, Wales.

Production errors

 * The Doctor switches off the TARDIS Monitor showing the data that he took from the robot. The next camera view shows the monitor still on, showing that data. Next camera change shows the monitor displaying the default screensaver.

Continuity

 * Images of Rose Tyler, Martha Jones, Donna Temple-Noble are seen. (DW: Rose, The Runaway Bride, Smith and Jones) The Doctor feels guilty for what he did to Rose, feel even guiltier for what he did to Martha and states he "screwed up" Donna.
 * The Doctor has no memory of the Silence (DW: The Impossible Astronaut/Day of the Moon)
 * The Doctor speaks about River at Demon's Run. (DW: A Good Man Goes to War)
 * Rory punches two people in the face to knock them on to the ground. Rory previously did this to the Doctor. (DW: The Big Bang)
 * River begins studying archaeology. (DW: Silence in the Library)
 * The TARDIS's projection of Amelia mentions fish fingers and custard. (DW: The Eleventh Hour)
 * Melody mentions regenerating into the toddler form of Mels in New York. (DW: Day of the Moon)
 * As this was in 1970, Mels would be two decades older than she appeared. She may have somehow used a method of time travel or, given her later reference to being able to control her aging process (planning to gradually "bring the age down a little" in her newest incarnation), it is logical that she prevented herself from aging at a normal human rate until she met up with her parents as children.
 * The Doctor switches Melody's gun for a banana, much as he did to Captain Jack Harkness in The Doctor Dances.
 * River reveals she learned how to pilot the TARDIS from the TARDIS herself. (DW: The Time of Angels)
 * The Doctor tells Melody "Rule one: The Doctor lies." (DW: The Big Bang) One of the first things the Doctor hears River say is "I'm always lying." (DW: Silence in the Library)
 * When the Doctor reveals that the crew of the Tesselecta use a compression field to miniaturise themselves into the ship, he tells them to watch what they eat, referring to the Slitheen's gas exchange. (DW: Aliens of London/World War Three)
