The Power of Three was the fourth episode of the seventh series of Doctor Who produced by BBC Wales. It saw to the reappearances of Brian and UNIT. Kate Stewart, daughter of the Brigadier, makes her first appearance in an actual Doctor Who story, rather than a spin off.

Synopsis

There have been many ways to invade the Earth, and the Doctor has seen them all – or so he always thought. And then the human race wakes up one morning and discovers the world has been overrun by… "very small cubes", which then proceed to… do nothing at all. A plan is afoot, humanity is endangered – but by what and how and, above all, when? Thus begins the Year of the Slow Invasion.

For the first time in his world-saving career the Doctor has to call upon one of the least of his virtues: patience. And the Ponds face something possibly more terrifying than any world-ending apocalypse: the Doctor is moving in!

Plot

After realising that they lead two lives, their "Doctor" life and their everyday life, Amy and Rory conclude that they should choose one to stick with; but then are whisked away on another adventure with the Doctor. After returning home, the couple settle back into routine.

But one morning they are by Rory's father Brian, who alerts them to the global appearance of small, black cubes. The Doctor, already there, quickly attempts to understand them. His experiments accidentally attract the attention of U.N.I.T. and a strike team quickly responds. After the team locks down the couple's flat, Kate Stewart arrives on scene and identifies the Doctor. She and the Doctor wish to continue monitoring the cubes, as it appears that due to the cubes' inactivity people have started taking them home and to work. U.N.I.T. departs as does the Doctor, leaving Brian and U.N.I.T. monitoring the majority of the inactive cubes.

Several months pass, with Amy and Rory taking on the commitments of everyday life. During their anniversary, the Doctor returns to take the couple on a journey through time once again. The trip takes on the usual mishaps; a few days journey turns into seven weeks. They return to the moment they left, and Brian questions the Doctor about the fates of his past companions; worrying about the Ponds possible future travelling with him. The Doctor asks Amy if he can stay with them and watch the cubes, as he misses them.

One day amidst everyday life, the cubes activate. Every effect is random, and the cubes inside the the Ponds' flat also activate. Around the world, many of cube's effects are dangerous. Rory and Brian leave to help the hospital with the recent injuries, and the Doctor and Amy are summoned by U.N.I.T. to the Tower of London. Captured cubes exhibit different effects; such as hacking national defence systems around the world. Soon the cubes become inactive again; the world begins to recover.

At the hospital, Brian crosses paths with two identical "orderlies", in reality non-human entities being used by a small girl holding an active cube to kidnap patients from the hospital. Having been discovered, Brian is kidnapped as well. Outside the Tower, the Doctor and Amy debate the merit of travelling the way they do; Amy considers it "running away" and the Doctor considers it "running to". During their conversation, the Doctor realises the cubes acted out to gain attention and scan the entire planet.

The power at U.N.I.T. goes out, and the cubes start a countdown from seven. At zero, the cubes open but contain nothing. Moments pass when around people suffer fatal heart attacks, with the Doctor experiencing heart failure with one heart. He and Amy leave for the hospital, where Rory notices his father's absence. The Doctor discovers the little girl with the active cube and reveals her to be a simple android overseeing the entire operation. The Doctor shuts her down and Amy restarts the Doctor's heart with a defibrillator.

The Doctor and the Ponds converge on board a spaceship through a wormhole in a "Out of Order" elevator. The two "nurses" are on board and are quickly disabled. Brian is taken back to the hospital by Amy and Rory while the Doctor meets the ship's on-board hologram. The ship was built by the Shakri, which in the Doctor's opinion are the "pest controllers of the universe". The stolen electricity was used to exterminate the human race; which the hologram thinks is a contagion to be destroyed. Returning to the ship, Amy and Rory watch the Doctor reuse the electricity to start the stopped hearts on Earth. The surge, however, destroys the Shakri ship just after the Doctor and the Ponds escape. Later that night, Brian urges the couple to continue to travel with the Doctor, believing that they should enjoy the opportunity to change the world.

If you'd like to talk about narrative problems with this story — like plot holes and things that seem to contradict other stories — please go to this episode's discontinuity discussion.

• After Kate Lethbridge-Stewart enters Amy and Rory's house, we see her take out her scanner. When she originally takes it out, her screen is facing the Doctor, and in the next shot, it is facing away from him.
• In some shots when the cubes are counting down from 7, some cubes are missing the numbers in one shot and then have them in the next.This can be seen at 28:01 when the doctor is in the room with the cube, and when the nurse is removing the cubes from the hospital at around 25:44.
• Day 67 of Brian's log was subsequent to Laura's engagement party, the on-screen caption for which showed it to have been in October. On 26 June, Amy told the Doctor that approximately nine months have elapsed since the cubes' arrival. The on-screen caption showed day 361 of Brian's log to be in July.
