"Once upon a time there was a girl named Rose Tyler and a boy called Jack, and they were best friends," said Melody, and the girls and Rory listened. "They were heroes, and they saved the world a lot."
"Like Wonder Woman?" said Lucy, whose cousin was in America. The other girls shushed her.
"One day, they went to a space station in the future, where space aliens were stealing people and making them go on reality television."
"That doesn't sound so bad," said Emma.
"But they were stolen," said Rory. "They didn't want to be on telly."
"Yeah, and the aliens killed the ones who lost on the shows," said Melody. All of the girls gasped, except for the ones who went ooooooh. It was kind of... satisfying. "Anyway, Rose and Jack found out about the aliens, and blew them up."
"They saved the world?" said Rory.
"Yeah," said Melody.
The room was silent for a moment.
"Good story," said Amelia.
