Doctor Who: 10 Worst Things Amy Pond Has Ever Done
8. The Beast Below - Reckless Decision Making
The Beast Below is Amy's first trip in the TARDIS, picking up directly from her and the Doctor's departure in the closing scene of the Eleventh Hour. And straight away, she's making decisions with potentially awful consequences.
With the revelation that the Starship UK is being transported through a tortured Star Whale the Doctor is left with a decision to see if he can save the creature, or as harmlessly as possible put the creature out of its misery. As is a theme throughout the story, there are two buttons with two options, this time presented to Liz Ten. She can either abdicate (releasing the creature), or get on with the way things are going with no memory. But Liz doesn't make this choice.
Amy sees that the Star Whale is kind to the children, and believes that it is here by its own free will. As a result of her theory, she makes Liz abdicate, and the torture of the beast halts, potentially leaving Starship UK to be destroyed. With that the ship rubbles, but then stops. The Star Wale continues to help the ship travel through space.
So whilst it all worked out for the best in the end, there is no way Amy could have been certain her actions would end as positively as they did. What if it didn't? Well, the whole of Starship UK would have been destroyed killing the entirety of the population of England, Wales and Northern Ireland (but not Scotland - they wanted their own ship).
That's two entries in a row where Amy is making questionable decisions with buttons, thankfully this one was the right choice, but the alternative would have been horrific.
