Karen Gillan's best moments as Amy Pond

3. Vincent and the Pond (Vincent and the Doctor)

Amy has a habit of being a bit cold, but Vincent and the Doctor saw her at her most emotionally vulnerable, as she agonised over not being able to save depressed painter Vincent van Gogh from suicide.

2. The introduction of Amy Pond (The Eleventh Hour)

Amy Pond's very first episode saw Karen Gillan introduced in a police uniform, having just finished work as a "kissogram", and knocking the Doctor out with a cricket bat. It's not the sort of introduction that anyone was ever going to forget quickly.
