First Ache
The Raggedy Doctor was real. Rory could hardly pull himself together enough to speak when he saw him. The aliens, the zombie patients, and the mortal peril seemed almost insignificant compared to the realization that Amy was right all along.
He was too real. So real that Amy wouldn't stop looking at him, wouldn't stop following him, wouldn't stop hanging on his every word. Rory wanted to throttle him, but you can't throttle a hero. You also can't measure up to one. He felt powerless to make her see him again, to look past the brilliant, handsome hero of her dreams and back into his eyes, but he wouldn't leave, not as long as she might need him.
When the Raggedy Doctor failed her again, his arms were the ones that pulled her close, his shirt the one stained with her tears. He knew he could never compete, but he could be the one who was there. So he stayed.
