He whisked her away from her bedroom, in the middle of the night.
At first, she couldn't believe that he was actually here, swept up as she was in the sheer magic of the moment. An impossible man standing in the middle of a place so familiar to her, blue box parked in a corner, barely a hairs breath away from her desk. Something so ordinary, containing something so extraordinary. But the doctor was nothing if not impossible.
The impossible man.
And when she first set foot into the old wooden box, she knew she was lost. She could see the possibilities of amazing dreams, tantalizing adventures shimmering around her, as though the very air surrounding the box was enchanted. Stories called out to her from the complex looking instruments, stories of creatures and happenings beyond her imagination. But also of sadness and incredible loss. Of untold years spent utterly alone.
Alone, maybe, but never forgotten. This man and his mad blue box were too important to forget. They shaped the destinies of every single thing in the universe. Every star, every planet, every galaxy that ever was or ever would be. The thousands of voices screamed at her, shouted at her with the voices of a thousand lives, all touched, all changed by him. It made her want to weep and laugh all in one moment.
She was feeling rather unarticulate at the moment, and her normally quick wit felt as though it had frozen in the presence of this incredible, impossible man. So all she said was, in a voice saturated with awe, "It…It's bigger on the inside."
He laughed and spun around, arms thrown out wide as if to embrace the whole of the TARDIS, "Yes! Yes it is, oh I love how they all say that! They do always say that you know. Well, it's not really that big compared to the universe, or all of space and time, but yes, it is quite big, relatively speaking, I suppose!"
She can't help but laugh when he says this, eyes bright and mischievous, planning the next stop already.
He turns and looks into her eyes.
"So where do you want to start?"
