Turn Left (A Phanfic based on the Doctor Who episode)

This is a Phanfic based off the Doctor Who episode, "Turn Left." In that episode, the Doctor's companion is drawn into the tent at an alien festival, of a women who attaches a bug to the companion's back, convincing her to turn left, on a road that would take her to a job interview or to somewhere else (if she turned right). If she were to have turned right, which she initially did, she would meet the Doctor and later become his companion. However, when the bug attached to her made her turn left, she never met the Doctor, therefore changing space and time as she knew it. A similar situation will happen to Dan and Phil in this story, with subtle hints at Phan, but mostly a story about what would happen if Dan and Phil never met.
