GR8 NRG
Amy walks into a room and within 5mins knows the personality of a starwhale and that is something the lowly doctor could never understand or pick up on.
Really, she likened the whale to the Doctor "
So that's how it works? You never interfere with people or planets unless children are crying?"
"
Yes."
The whale turned up to save the children who were screaming and crying. She put together the clues on an emotional scale. That's what companions do.

Amy even won WWII thanks to that last flying spitfire to be used as a prototype for more to be made and win the war in one night.
She never won the war.
The only war that was won in that was the one against the Daleks as far as protecting the human race goes. Even then, that wasn't even her, she just suggested that they use the smarts of the Android to come up with a solution. In all technicality it was the combined effort of the Android, the fighter pilots and the Doctor who did that.
Not Amy.
