Author's Summary: There were always surprises with the Doctor. Delaks. Cybermen. His regeneration. Hers.
Characters/Pairings: Rose Tyler, the Doctor (various future forms)
Recced Because: The idea of the Bad Wolf imbuing Rose with Time Lord qualities, including regeneration, was visited and re-visited in lots of fanfic stories after Parting of the Ways came out. "By The Numbers" stands out because it's a "Rose Regenerates" story that really and truly gives her a life of her own, nine times over. Instead of focusing on telling a short story in detail, it spins Rose's lives out across the centuries, in broad strokes, by the numbers. It explores what is lost when Rose becomes more than human, how this affects her and the person (people) she becomes. Rose's new (and not wholly wanted) alien life intersects with the Doctor's, of course, but also is not defined by it. We see first hand how, with a Time Lord life span, everything is fleeting.
She had left him for the first time not long after they changed - well, not long for them, but she supposed twenty years is a long time for humans. It was time, and they had both known it. She needed to be on her own for awhile. She needed to learn how to be on her own because, if she continued to regenerate, then some day...
It had been hard, but it had been right. He left her in fifty-second century Earth on May 14. She had a hundred years to explore on her own and then return here to the fifty-second century on May 15. That had been a hard century, but she had made it through. And then they were together again. Until she changed.
