It was early morning; one of the rare ones, when the all inhabitants of the TARDIS slept deeply. Their last adventure had ended on a bittersweet note, and none of them would look at the time machine the same way again.
In his sleep, the Doctor dreamt. Mostly bad dreams, erased on waking, but some good. All on this day centred on Idris.
He pondered her name. It sounded so like TARDIS, but the body the TARDIS'S soul entered was already called Idris- coincidence? And the message she'd given the Doctor from Rory. The only water in the forest is the river. What did it mean?
He yawned, stretched, walked down to the kitchen for breakfast. Someone was already there. The Doctor murmured a hello. Amy? Rory? His brain was a cloudy fog.
When he was halfway through his breakfast, suddenly- click.
The Doctor fell off his chair in shock. There on the bench, perched cross legged with a serene face, sat Idris herself. The TARDIS. His TARDIS. A woman!
Amy was right; maybe he HAD wished really really hard.
