10 Best "Everything You Know Is A Lie" Moments In Doctor Who

10. The Bracewell Bomb (Victory Of The Daleks)

When the Doctor and Amy turn up in World War II London, they discover that Winston Churchill and his scientists have developed a new super-weapon to use against the Nazis. He calls them Ironsides, but the Doctor (and everyone watching at home) immediately recognises them as Daleks.

In this episode, Skaro's favourite sons - or daughters, or others, it's never quite explained how Dalek genders work - were supposedly invented by Professor Edwin Bracewell, a kind Scottish fella who seems immensely proud of his work.

However, halfway through the episode, poor old Bracewell's reality is shattered when he discovers that he didn't create the Ironsides. In fact, they created him. Oh, and he's also a bomb that's about to explode. Talk about kicking someone while they're down.

Bracewell had memories of a life he'd never actually lived, which was a particularly cruel thing for the Daleks to do, even by their standards. But on the plus side, those memories come in handy during a heartwarming scene where Amy forces the Professor to embrace his humanity, which cancels the countdown on the bomb.

You feel genuinely sorry for Bracewell as he desperately tries to cling to his implanted human emotions and memories, and it makes for a strong emotional beat (and a standout moment for new companion Amy) in an otherwise average episode.
