The one that makes no sense at all.
Written by the Children of Ashdene School.
Behold, another story that was the byproduct of a Blue Peter contest. In 2012, the Eleventh Doctor and company were stuck in the Land of Fiction and needed somebody to write a story for them to get out. That should be your first clue things are about to operate really high on the silly spectrum. "Good as Gold" is more of a "let the writers do as they please" story, after all, being a children's script. This is a Lighter and Softer tale, where the rules don't apply on continuity because it's taking place in a fictitious reality. Anything is possible, even things that don't make sense. Naturally, characters act even goofier than usual. That, and a Weeping Angel is thrown in to mix, with extra powers just for fun.
And now, a reading from The Other Wiki:
Amy reminds the Doctor he needs to have an adventure once in a while, the Doctor complies and sets the TARDIS to its "adventure setting". After a series of malfunctions, the ship lands in the middle of the London 2012 Olympic Games, where they are visited by a panicked Olympic runner, who claims he is being chased. His pursuer is revealed as a Weeping Angel, who is seeking to seize the Olympic Flame and rob the planet of the good will and spirit it symbolizes. The Doctor vanquishes the Angel with the sonic screwdriver, and the runner resumes his mission. Before he leaves, he gives the Doctor his gold medal. As the Doctor prepares to embark on another adventure with Amy, the Weeping Angel begins to re-form....
- Absentee Actor: Rory is missing.
- Canon Discontinuity: As with the previous Script to Screen special, although this one has the excuse of happening in the Land of Fiction.
- Continuity Nod: The Doctor once again winds up in the 2012 Olympic Games.
- Desperate Object Catch: The torchbearer does this via Diving Save when the Weeping Angel steals, then drops, his torch.
- For the Evulz: The Weeping Angel is going to steal the Olympic torch, which represents the good will and spirit of the Olympics.
- I Meant to Do That: When you turn on the adventure setting, apparently it's supposed to emit sparks and blow bits up. And give the Doctor a facefull of steam, ruining his hair.
- Not Quite Dead/The End... Or Is It?/New Powers as the Plot Demands: ...since when could Weeping Angels reform? It might have a new ability because this is taking place in the Land of Fiction, where anything can happen contrary to the rules of reality. If you want it to reform, it can do so there.
- Series Continuity Error: This episode directly contradicts "Fear Her" where the Doctor is the one carrying the Olympic Torch in the stadium.
