15. Amy Pond Melting And Then Waking Up In A Creepy Alien Lab
Hey look, it's that "Earth-shattering" Series 6 twist that nobody saw coming. Apart from the Eleventh Doctor, apparently, who had known that something untoward was going on with his beloved companion Amy Pond since the US two-parter but chose to keep his suspicions to himself rather than doing something useful like actually helping her. As such, destiny finally caught up with the girl who waited at the end of The Almost People when she went into a phantom labour in the TARDIS before melting and waking up in a creepy white tube where she was about to give birth to the baby she didn't knew she had. She'd had better days. A genuine "WTF?!" moment because Amy was just as confused as the rest of us. And it was all downhill from there...
