Instead of sitting around envying those of you guys who have the discipline to write fanfic, tonight I thought I'd just throw out some of my deeply silly ideas in case anyone had the burning desire to write them up for me :) I'd also be interested in any how-to-get-it-together-and-write tips that you might have.
1. Ten/Barty Crouch Jr.
Barty stows away on the TARDIS disguised as Martha. Our beloved Doctor, of course, remains entirely oblivious to Martha's new habit of swigging away from a little bottle of foul-smelling shape-changing potion in her jacket pocket, until Something Happens (e.g. Barty starts to wonder if he oughtn't change shape to resemble Rose instead?). I really wanted to write this story in order to pick up on some of the "change to live"/"please change back" angst from series 3.
2. Ten/the entire population of Gallifrey
Turns out that Time Lord culture resembles that of bonoboes. The whole Time War got started because they wanted to sex up those sexy dildo-esque metal pepper-pots and the Daleks interpreted this as a hostile act. The Doctor hopefully suggests that Martha help him re-enact a beloved Gallifreyan holiday ritual where two friends each pull a train. One of the train-passengers, like a Christmas cracker, is bearing a paper crown for the Doctor to wear.
... I dunno, what do you think? Too obvious or cliched? Would love to have your opinion(s) in comments....
