In which Sally Sparrow is a main companion of S5, instead of the Ponds. S5 - S7 I heard somewhere that Sally was meant to be a main companion, but Carey (the actress) turned it down. I thought it would be cool to have the same plot points of S5, but with Sally and Larry instead. Please bare in mind, that we don't have much of Sally as a character, so a lot of plots and character choices will be of my head canons.

On a mission to save the world, the Doctor encounters Sally Sparrow. Sally wants to help the Doctor, who once saved her life. But the real question is, how did Sally end up in 1863? (Disclaimer: I do not own the Doctor Who characters or names, the storyline however is my own.)
