The sight of his best friend falling though the archway would stay with Lupin forever. The last of his school friends - the others dead or soon to be. The irony, that the one who had the least to live for, was the last left alive.

James, Lily and Sirius had Harry to live for; Sirius had just gotten his life back. He, Lupin, had no-one. Sure, he had friends, acquaintances, people to talk to. That was more than many like him could claim. He was fighting a good cause that could rob him of his life in an instant.

He was the only one left to tell the story of Harry's life; the only one left who could claim a tie back to Harry's family (who didn't want to kill Harry of course). So he had to live on. He had to give Harry all the protection he could, all the protection Lily, James and Sirius would have given him.

AN: This is something that I have wanted to write for a while. I know it's short but please review. I don't own the world of Harry Potter.
