I don't own Doctor Who, I'm just a silly American teenager.
Feedback would be greatly appreciated. Please?

Prevention

Everyone he gets close to is lost, it was a fact. At some point in his longer-than-a-human life, he had figured this out, and the Doctor had started blocking his companions, hoping to prevent their inevitable loss.

He had tried to block Rose out, too, but somehow she had broken past all of his defenses, worming her way straight to his hearts.

He knew there was no going back, he could never un-fall in love with her, but sometimes he wished he could, just to save her.

He could never prevent the inveitable: losing her.
