The TARDIS knew. She was connected to the Doctor. She'd seen everything that had happened with Rose, the Doctor and Mickey, when they had gone to France. Everything about Reinette and the Doctor. Soon, they all wandered back on board, but it was nearly midnight, so the Doctor slowly set the controls to shuffle, which set the TARDIS drifting gently past galaxies.
She knew exactly what Rose was feeling, what she had seen. As the Doctor was reading Reinette's letter, Rose had looked round the door. She had wanted to see him, to make sure to her that he wasn't fond of Reinette.
But instead of him sitting reading, as was his usual habit, he had his back to her. He was reading the letter. Rose's heart sank further than it ever had in her whole life. The Doctor had simply abandoned her and Mickey, and jumped through the mirror to go gallivanting off to France.
Rose looked up at the ceiling.
"Help me. Please."
She thought as loudly as she could. Soon, she was transported to the most beautiful room she'd ever seen. It was apple green, with matching carpet. The duvet on the slim metal bedstead was cream, and had a pattern of apple blossoms, like the soft silk cushions piled up at the head. It was late dusk outside, and she could hear a sweet chirping of birds from a small walled garden.
The heady aroma of apple grass floated in through the window, along with the scents of the flowers overflowing from pots outside. Through a pink door to her right there was a pink walled bathroom with a china sink. Rose was soon changed into a pair of plaid pyjamas, but as she was brushing her teeth, she caught sight of something that didn't match its surroundings at all.
It was a pocket sized notebook, at least ten inches thick, with thin cream pages that were completely blank. Rose decided to write. English had been her favourite subject at her school, the one she'd always done well in. But she couldn't write fiction now.
This night was the start of The Companion's Diary. This was the first entry ever made.
