The Doctor watched his old companion wander around the TARDIS in her formal wear with a grin on his face and his shoulder resting against the jam. It was brilliant, and so familiar, like waking from a dream and finding that just a little part of it was real. And the Doctor had retained the best bit of the dream. He'd been able to keep Rose.
Taking off his cape, the Doctor tossed it over a bit of the TARDIS and then strode up the walk with his hands in his tux pockets and a little bounce in the balls of his trainers. "You have no idea how brilliant this looks," he grinned, looking pleased as punch as he gestured at Rose, and the TARDIS in general. And the ship, she was happy. Very happy. Every bit of her shone a smidge brighter, and the humming noise that was a constant, even when she was in less than the best shape in the world.
"I'm just glad you're here," he admitted with a little shake of his head, smiling at her. "You know, she kept your room just like it was," he grinned, gesturing down the hall toward Rose's room. That was a fairly consistent thing the TARDIS did with all of the Doctor's companions over the years, but he figured that Rose might like to see her old room.
