Scene: One of the last episodes of Series 2 of the new Doctor Who (the 10th Doctor) Characters:
- Rose Tyler, companion of the Doctor as he travels through time and space
- Jackie Tyler, Rose's mother
Jackie: Do you think you'll ever settle down?
Rose: The Doctor never will so I can't. I'll just keep on traveling.
Jackie: And you'll keep on changing. And in forty years time, fifty, there'll be this woman, this strange woman, walking through the marketplace on some planet a billion miles from Earth. She's not Rose Tyler. Not any more. She's not even human.
Except that's not how it works. If Rose changes, she won't be the same Rose her mother remembers (and perhaps this is what her mother is referring to). If Rose changes, she's still Rose. She's just progressing, changing, adapting, learning, growing, pick your favorite synonym, it's what everyone does as they progress through life. Are you the same person you were ten years ago?
I thought not.
