Well, that's usually how i do things. I have to think of the ideas and they usually come along as I write. I can't settle on forming a plot, even as much as I have tried. I can jot down ideas, but I can never form them into a plot at all.
I do want the doctor to notice the cuts on her arms. She self-harms as a way to release her emotional pain. I want it to be kind of a cute little moment. I also thought of saving the part where he finds out she's immortal until after they find someone else who is just like her. Is there anyway that Torchwood could have been involved with her past? Like, maybe they were doing all sorts of experiments on her? Or would that be too OOC for Torchwood? I mean, it does take place after Journey's end, but before the big battle where the doctor is forced to regenerate. I think Torchwood could play a part still because she has no memories from birth until the age of twelve.
I don't know. I'm just throwing out some options here. ><
