I took some liberties with the formatting for this, as I'm a firm believer that grammar rules are always second to the emotions and tone of the scene, so if you don't agree with that, proceed with caution? I don't know why this would actually matter but I figured I'd put a warning in, just in case.
Once upon a time there was a young girl named Melody. Melody was lost and alone and oh so very scared. She was scared of lots of things, but all of her fears could be traced back to the spaceman. The spaceman who had killed all of her people, who had been the reason she was taken from her mommy and daddy, who never saved her. Never, ever, ever, ever, ever. And she was so scared and she sat in that old building with the poor man who really had no idea what he was doing and things happened, scary things, and she was scared, so she ran.
And she ran and ran and ran and now she's Mels and life isn't so bad, now is it? She has friends, she's gorgeous, crazy as hell, and she could do anything she'd like, but still she must go back to the woman with the monsters and deep down in the pit of her belly she's still terrified and she still knows it's the damned spaceman's fault and so she lives life scared but now there's something different, oh, now there's something vital and dangerous and hilarious added to the mix because now she knows what the spaceman goes by and she lives off of her hatred for him and the knowledge that one day she will kill the Doctor.
But she had her chance, oh she had her chance in 1940 but she couldn't because he had confused her, had looked at her and she hadn't felt hatred in the pit of her stomach, no she'd felt something else entirely, so she gave up her regenerations just for him and when she wakes up in the hospital bed and looks at the gorgeous blue diary she can't do it, she can't take it, only she did take it and she ran and ran and ran with it.
She goes to university and she gets a degree and she realizes she has a passion for something and isn't that just hilarious, all this time she's never been allowed to think for her own and once she's finally free the thing she loves the most is the only line of work that he is always involved in whether he means to be or not.
Only she's wrong. She's not free. She'll never be free, and she doesn't realize how true that is till she's forced to kill the man she thinks maybe she loves loves? and she'd never been a hero, always been a selfish coward so even though if she doesn't kill him all of mankind will suffer terribly, she can't do it, can't kill him, so she ran and ran and ran
and suddenly he doesn't know who she is, doesn't trust her, and oh fuck that hurts and she thinks maybe if she just stopped doing this, stopped interacting with his younger self, maybe they'll never meet and maybe that would save them both a lot of pain but she can't do it, can't make herself, so she sticks with him all the way up to the library, all the way up to her death, and as she smiles through her tears at a Doctor that doesn't know anything about her, all she can think is
no more running
