Ex-companions must have to deal with [the Doctor’s influence] for the rest of their lives, but we hardly ever see them again. Realistically, that would be the highlight of your life, the most extraordinary thing. You’d never be able to watch a science program without laughing at it. Everyone would speculate about life on other planets, and you’d know. It would change your life forever. The series has always been the story of how the companion changes, not how the Doctor changes. The Doctor doesn’t change very much. That’s always the story. - Steven Moffat [x]
