Out of the darkness came the sound of a door opening. Footsteps echoed in the hallway leading up to the Doctor's room, and he shook, knowing what was coming for him. As his captor stepped into the room, he started to cry. His worst enemy had entered: fangirls.
This particular fangirl was vicious. She had caught him on his way back to the TARDIS and hit him over the head with a big rock. Now she had him tied up in a warehouse, and nobody knew he was there. Normally he would push through it and come out the other end fine, but with her, it was different. He didn't want to escape, if he was being honest with himself. He liked this human. She knew what she wanted and how to get it, and when she had captured him, he didn't resist as much as he should have.
He couldn't resist once he knew he situation. It was her birthday, and he was the only present she had ever received. She had told him all about her life, and it was not a happy one. He learned about how she dreamed about flying away with him, away from her family and everyone who hated her, and how her parents tried as hard as they could to crush that dream. She told him about Mike down the street and all the terrible things he had done to her when he had his parties. He invited her over with good intentions, but a few beers later…
She had also told him about Kelsey, her "friend" with the drug habit. Any money she had ever earned went directly to Kelsey, and nobody knew. He felt bad for her, so he couldn't exactly say no when she kidnapped him. He was all she ever got to keep for herself, so he stayed. He didn't try to escape, and he let her do whatever she wanted with him. To an extent, at least. He would make her a cake and hug her, but he wouldn't go any farther, and he wouldn't make her anything with pears in it. And after a year, he would leave. She would have to deal with her life and let the Doctor save the universe again. No exceptions.
Lately she thought maybe he would change his mind, though. Not about leaving; he could barely stay on Earth for the year without being bored to death, but maybe about her staying here. He had been nicer to her lately, telling her more about his adventures and describing planets he thought she would like to see. So she let herself hope, just a little bit, that maybe he would take her with him when the year was up. Maybe she could travel the stars with the Doctor and run away from her problems here. All she ever wanted was to leave this planet. Maybe he would give her a birthday present this year, too. Maybe she would have the chance, for even a few minutes, to go somewhere else, somewhere with the Doctor, somewhere that she felt safe. Maybe this year, the Doctor would say the words this year: "Happy birthday, Reilly. Come with me and I'll show you the universe."
