The Girl Who Waited (TV story)

 was the tenth episode in the sixth series of Doctor Who. The unique moral choice at the centre of the story made it a character study of the relationship between Amy and Rory.

Synopsis
Amy is trapped in a quarantine facility for victims of an alien plague on Apalapucia – a plague that can kill the Doctor in a day. The Doctor can use the TARDIS to smash through time and break in, but then Rory is on his own. He must find Amy and bring her back to the TARDIS before the alien doctors can administer their deadly medicine. Rory is about to encounter a very different side to his wife. Can he rescue Amy before she is killed by kindness?

Plot
The Doctor takes Rory and Amy to the planet Apalapucia, supposedly a top holiday destination, but they arrive in a clinically white room, its only exit a door with two buttons. As Amy steps back into the TARDIS to collect her phone, the Doctor and Rory pass through the door using one of the buttons to find a white room with a giant 'magnifying glass'. Amy follows but uses the other button. She finds a similar room, but no sign of the others.

The Doctor realizes that Amy hasn't joined them. He discovers that she has ended up in a second, faster time stream, but he is able to talk with her through the glass scope. A week has already passed for her. The Doctor and Rory soon find a faceless, white robot, who explains they are in the Two Streams "kindness facility", helping to deal with a plague, Chen7, that affects only races with two hearts. This includes the native Apalapucians and Time Lords. The robot, and others like it, do not recognize the two as alien life forms, and tries to inject them with 'medicine' that would kill them. The Doctor warns Amy, and tells her to wait. He will rescue her. Rory and he race back to the TARDIS with the glass scope, using it to lock onto Amy's time stream to effect her rescue. The Doctor, forced to stay in the TARDIS for fear of the Chen7 virus, gives Rory his sonic screwdriver, the glass scope, and a set of glasses that allows the Doctor to see, hear, and communicate with him, guiding him to find Amy.

Rory explores more of the facility, but soon is set on by more robots. He is saved by a much older Amy, a fugitive who has hidden from the complex's sensors for thirty-six years. The Doctor has locked onto her time stream at the wrong point. He tries to get Rory to convince the older Amy to help locate the younger one. The older Amy is bitter, having waited as the Doctor instructed. She has been alone for thirty-six years, save for the complex's computer interface, and a disarmed robot she calls Rory. She refuses to help, knowing that saving the younger version of herself would mean she never existed. Rory angrily blames the Doctor, saying that he should take more care and the two begin a bitter row. The Doctor states that he dislikes travelling that way, causing Rory to storm off, dropping his glasses. The Doctor detects signals from the younger Amy nearby, and Rory finds her through the glass scope, weeping. Rory sets the scope to allow the older Amy to speak to her younger self, but the older Amy repeats that she experienced this before. Hearing her future self warn about the time streams convinced her to wait out for rescue. Rory manages to convince the older Amy to change her mind. Realising that time can be altered if you are aware of the future timeline, as Amy is, the older Amy decides to help, but demands that the Doctor take her too. The Doctor says this is a difficult but not impossible action and agrees. As Rory reroutes a control panel that maintains the facility's time streams, the Doctor helps the two Amys synchronize their thoughts, letting the two exist at the same time.

With these changes, the Doctor's glasses fail. Rory and both Amys must race through groups of the robots to get to the TARDIS and safety. As they near its location, the older Amy falls back to protect the other two. Younger Amy runs into a robot and is sedated. As older Amy covers his back, Rory takes younger Amy into the TARDIS. The Doctor slams the door behind him.

The Doctor tells tells Rory that it is impossible for both Amys to exist in the same time stream. Rory must choose which Amy he wants. The older Amy and he have a tearful farewell at the shut TARDIS door before Older Amy tells Rory to move on without her, and is taken by the robots. Later the Doctor and Rory have resolved their issues with each other and Rory asks if the Doctor knew all along that two Amy's would never work, the Doctor simply states that he promised to save Amy and he has, Rory now feeling gratitude for the Doctor's actions walks over to Amy who wakes up and asks for her older self. Neither the Doctor nor Rory can answer her.

Cast

 * The Doctor - Matt Smith
 * Amy Pond - Karen Gillan
 * Rory Williams - Arthur Darvill
 * Check-in girl - Josie Taylor
 * Interface (voice) - Imelda Staunton
 * Handbots (voice) - Stephen Bracken-Keogh

TARDIS

 * The Doctor's TARDIS apparently has a karaoke bar, and a collection of DVDs.
 * When old Amy puts her hand up on the glass of the TARDIS door, her hand can also be seen on the glass from the inside. This is the first time on screen that this effect has been seen, indicating the TARDIS door windows are not opaque.

The Doctor

 * The Doctor is still willing to accept blame for the TARDIS landing too late in Amy's timestream, even though DW: The Doctor's Wife established that such misdirections were often the result of the TARDIS herself making a decision as to whether the Doctor would land.

Story notes

 * The episode's original title was The Visitors' Room. This changed to The Visiting Hour and later, the one-word title, Kindness. Despite many reports to the contrary, there was no late change to the adventure's title and at no point was it ever called The Green Anchor.
 * The cast list for this episode is the shortest of any full length episode of modern Doctor Who.

Ratings

 * UK Overnight: 6.0 million

Myths
The episode was going to be called The Green Anchor. This was proven false and was also denied by the writer.

Continuity

 * Clom is mentioned as being a location of a future Disneyland. (DW: Love & Monsters, The Stolen Earth)
 * Rory mentions the Doctor's fez. (DW: The Big Bang)
 * Amy previously saw past/future versions of herself in DW: The Hungry Earth/Cold Blood, The Big Bang, and Space/Time.
 * The Sonic screwdriver was previously referred to as a sonic probe by the Daleks in DW: Doomsday.
 * The TARDIS previously was only able to sustain a paradox by the rebuilding of its time rotor into a paradox machine. (DW: The Last of the Time Lords)
 * The Mona Lisa is shown. The famous painting (which in reality is somewhat smaller than the one shown here) was previously featured in DW: City of Death and SJA: Mona Lisa's Revenge. It's left ambiguous as to whether this is the original Mona Lisa (doubtful, as the original Mona Lisa was painted on wood and not canvas), in which case it may still house the consciousness depicted in the Sarah Jane Adventures episode, one of the "this is a fake" copies from the Fourth Doctor story, or a simple replica.
 * The glasses which the Doctor gives to Rory are somewhat similar to the Eye-5s from Torchwood.
