A/N: Rose has always been my favorite companion, and I always wondered how 11 would think of her. That is how this story was born.
The Doctor sat in his usual chair in the library, a tattered copy of his favorite book lay open in front of him. His eyes began to feel heavy and soon he had slipped off to sleep.
"Doctor?" Rose asked. She sat down on the armrest of the chair and closed his book, then reached down and straightened his bowtie.
"Come on, let's go to bed." Rose grabbed his hand and gently guided him to bed.
"Rose, I can put myself to bed."
"Well you sure aren't doing a good job of it," she quipped as she pushed him into bed and then sat down on the edge of the bed, as if waiting for him to invite her in. Rather than ask her to stay he pulled her in for a kiss, wrapping his arms around her and tangling his fingers in her hair. She responded to him eagerly, pushing him back against the bed and then straddling his hips. She continued kissing him, her hips pushing rhythmically against his.
Hours later they were sprawled in bed, the sheets tangled loosely around them; her head rested on his chest, one arm draped across his chest while he stroked her arm gently.
"I love you, Rose Tyler."
"I love you too, Doctor."
"Doctor?" Amy's voice roused him from sleep. He started and looked up at her confused. Why wasn't he in his bed? He almost asked Amy where Rose was, and then he remembered where she was. In the other dimension, with a human copy of his younger self. He closed his eyes and looked away from Amy.
"What do you dream about that makes you so sad?" Amy asked him. She sat down in the chair next to him, waiting for a response.
He contemplated not telling her, but when he looked over at her she was waiting silently. "Rose, I was dreaming of Rose. All of the things I should have told her, and all of the things I missed out on with her. I never…" His newfound courage dried up and he turned away from Amy, not wanting her to read the pain in his eyes. "I never told her how I felt."
Amy put her hand on his arm and gave it a reassuring squeeze. "She knew."
He smiled at her and then nodded gently. After a few minutes he stood up and led the way out of the library.
"Alright, where to next? How about some place warm? And preferably some place with running water. Not that it wasn't fun to visit medieval London, but the smell of the townspeople is one that I could live without."
Amy smiled and shook her head, laughing softly to herself as he continued to list off possible destinations for their next adventure.
