Karen Gillan's best moments as Amy Pond

1. Amy meets her older self (The Girl Who Waited)

The Girl Who Waited was Amy Pond's ultimate episode. For not only did it see Karen Gillan at her acting best, but it saw Amy confront her older, bitter self. It's filled with great moments - Older Amy's lonely den, the Doctor shutting the Tardis door in her face - but this scene, where they both talk about their love for Rory is particularly poignant.
