It was a funny thing, faith. The last time he'd come into contact with it he'd met the devil. The real source of every concept of evil in the universe. A being with the power to withstand the pull of a black hole. But he'd had faith in her, his pink and yellow human. She was what he believed in. More than anything, he believed in that girl.
Now he was faced with a reversed situation. The girl before him had undying faith in him, and that's what the Minotaur was feeding off of. So he had to break her faith in him. Remind her that she went through fourteen years of waiting and four psychologists for him to come back. Prove that he was unreliable. He wasn't what she always thought him to be.
He had to do it then, because he knew that if Amy was taken then he would be next. Rory didn't really have faith in much. But him? He had lingering faith in everyone he'd ever travelled with. Predominantly Rose. It may have ebbed since their time spent apart because it hurt so much, but it was still one of the strongest things he felt. Love and faith, all different kinds of each, were his predominant emotions. If the Minotaur started feeding off his faith, they'd be dead in a heartbeat. The intensity of his faith and love would render the Minotaur unstoppable. He had to make sure that the opportunity never presented itself.
He made Amy think about how she had waited in her garden all night when she was seven, waited on a man who said five minutes but would take twelve years. The "quick trip" had turned into another two years. He made Amy remember the little girl who spent her life waiting for a Raggedy Man who would take so very long to arrive. A very long time indeed.
A/N: Normally, I feel very weird writing anything about Rose and Eleven. He seems to have repressed everything from his former incarnation outwardly. But my friend and I were discussing what he could've seen in his room, and my friend thought he would see Rose, because of his words during The Satan Pit about believing in her. While I disagreed with him on that one because the rooms contained what they feared, I thought that it would be pretty disastrous if the Doctor was targeted in The God Complex. So yay for repressed emotions and selfless-but-at-the-same-time-selfish desperation for them not to come up!
