Edmund and Polly are best friends. Polly has zero idea that Narnia exists, and she doesn't realise that Ed was once a king. When she goes there whilst waiting for the train home after Peter had gotten into a fight, she has about a million questions zipping around in her head, including "Why hasn't Ed told me about this?" She learns to love Narnia, and grows ever closer to Edmund.
What a way to spend a train-ride home!
I do not own Narnia or any of the Pevensie's or Polly Plummer (The Magicians Nephew. This is where Polly got her name. NOT THE SAME POLLY, THOUGH.). I only own the story.
