Welcome to the end, loves. But then, of course, there will be the one-shots, which I hope you will all enjoy. They'll fill the story out so that you can get more of a sense for the characters and whatnot.
But yes, this is the end of the summary. Hope you enjoy it :)
The TARDIS faded, as the Doctor had said it would. When it was past the point of extendable life, they made their last trip home to London and left it, as John had once told Rose to do, as a funny little thing standing on a street corner near the Tyler estate. Though they visited it often, her lights eventually dimmed and it was too dark (and too dangerous, without her to guide you through the halls) for them to keep her proper company. Tardis insisted on a sleepover one night, but John, who had begun aging once the TARDIS appeared, soon complained that the grating was cutting into his back, and they'd had to give up.
So they gradually stopped visiting, merging back into a life in Torchwood. John's hair began to show the subtle signs of graying, but the domestic life was one that still irked the living daylights out of him.
Months later, it was a perfectly ordinary day. Tardis was arguing with Pete about the merits of installing a lift-entrance with a perception filter in the ceiling of the Cardiff Torchwood division, when John came running in. He had been gone, down in Wales on a field expedition to dig up a fallen meteor that had proven to be a bit more trouble and a bit more fatal than they'd anticipated. John skidded to a stop, narrowly avoiding barreling Pete over in his haste to brandish an orangish chunk of rock and grin triumphantly at Tardis. He looked younger. It wasn't so much that the grin and excitement took years from his face. It was that years had been taken from his face.
"Piece of Gallifrey," he declared, eyes snapping. "Must've been blasted over from the Time War. Probably what caused that weak spot that allows the Rift down in Cardiff. Reacts with my Time Lord DNA, revitalizes. I may not be able to regenerate, but it should slow my aging down just enough for you to catch up." Without waiting for a reaction, he continued, hinting, "Guess what else it does." His eyebrows went high, making his forehead wrinkle.
Time Lord, Gallifrey… Tardis barely gasped before she grasped his hand and took off at a full-out run.
It was a long run. They were both winded by the time they unlocked the doors of the TARDIS with trembling hands. A light switched on as soon as they stepped inside.
Wide-eyed and open-mouthed, Tardis turned to John. "How much of that have you got?"
He reached into the pockets of his old, beaten leather jacket and started removing Ziploc after Ziploc of orange rock, until there was a medium-sized mountain of it. He looked at Tardis, that old twinkle coming back to his eyes. "Where do you want to go first?"
Jackie always said she should have expected it, really, when she named her daughter Tardis. They came and went regularly. Time never meant the same thing to them as it did to the rest of the universe (even though one day it did catch up with them when they noticed the grey in their hair).
But there was one thing that they were always happy to do like everyone else – for once in his very, very long life, the Doctor was able to live life day after day. Just this once, it was an adventure that he could have.
