10 Doctor Who Moments You Didn't See Coming

10. The Regenerating Child

Series 6's Day Of The Moon ended like most other episodes of Doctor Who: the main gang (in this case, Amy, Rory, and Eleven) is back in the TARDIS, bantering around, reflecting on the adventure they've just returned from.

But wait, what's this? There's an extra, MCU-style tag at the very end? The story suddenly skips ahead six months to a dank New York back-alley, which is a very jarring turn at first - that is, until the mysterious young girl we'd been tracking throughout the last two episodes emerges from behind a bin.

Things get very weird, very fast when she casually tells a nearby homeless man "I'm dying - but I can fix that". And then - in a truly what the hell moment - her hands start to glow with that iconic golden energy, and she bursts into a full-on regeneration.

We first met this girl in the previous week's episode, so there were already a lot of theories about her possible identity. But wherever you stood on the matter, nobody expected her to regenerate here. That look of shock and confusion on the homeless man's face was pretty much reflective of the viewing audience at home.
