AN: Based off Depeche Mode's 'Wrong'. Not really sure I got Rory's character down, but I tried. Though, he's bound to be a little OOC, seeing as starvation messes with your brain. Here goes nothing.
Rory Williams, the nurse. Never quite a doctor, though he was used to that. As he steps on the scale, he not-so-fondly reminisces on his childhood—how he and Amy would play in the field, playing Doctor. How she would rebuke him, telling him that he wasn't like him, how he was so, so wrong. And he knows that he is still wrong, that he is fat and unlovable, but one day, he'll be skinny; skinnier than the Doctor in his damned tweed jacket and manic grin, and she'll stop waiting because he's better than the Doctor and already here. He knows that, now, he only has half of her. But maybe, if he loses half of himself, she will replace it.
The number flashes on the scale, and he tastes bile in his mouth. He knows that this is wrong, because he's a nurse and he's studied this thing that's taken hold of him, this thing that's mutated from jealousy and inadequacy to something sinister, but he doesn't care about that at the moment. All that's in his head is the fact that the number is half a pound higher than it was yesterday, and that Amy will never love him now because he's so fat and disgusting and so damn wrong; no wonder his parents were never proud of him, no wonder Amy and the Doctor ignore him, because he's the extra, the spare, and maybe if he gets rid of the spare fat, he'll be first.
Because, that's all he's ever really wanted, he thinks as he steps back off the scale, his defeat palpable. To be more than average, mediocre. To be more than just another nameless face wandering the world. And that'll never change because he's so fat and out of control that he can't even lose weight, and with that realization he sits on the bathroom floor and cries.
He knows that Amy will never want him, because the Doctor is a man, ancient and strong and unbeatable, and he gives her all of time and space. And Rory is nothing but the same little boy, always wrong, and with only his love to give her—something she's never really taken.
