So I'm thinking about the Fourteenth Doctor, and the bi-generation, and how he may have come to an end. What happened to him after those years he spent with Donna and her family, and with so many other friends on Earth (oh, I am headcanon-ing, friends), existing day-to-day and beginning to heal? After he learned how to let himself be loved, and shown compassion, and forgiven—and, eventually, learned to love, forgive, and care for himself? What happened when, at the end of this journey, his regeneration energy (I assume?) traveled back (in some hand-wavey fashion) to become the Fifteenth Doctor, who is born out of that love and forgiveness and compassion and is ready to move forward in the universe?

Fourteen becomes Fifteen—but what about the TARDIS?

Fourteen's TARDIS was created for the same reason Fourteen was: they needed to slow down, to be gentle. They needed to find a home that wasn't moving at the speed of light. So maybe this TARDIS is a little gentler, too. Maybe she's a little more careful of herself and her charges.

When Fourteen takes Rose to Mars, they land right where they're supposed to, and Rose sees wonders. Nothing bad happens, and they return home five minutes after they left.

When Shaun wants to see a football match from 1988, he opens the TARDIS door and she takes him right there, flying all by herself, to Fourteen's chagrin.

When Fourteen takes Mel to New York, they have adventures that don't involve running, or hiding, or screaming with anything but laughter. When Fourteen takes Jo, Ace, and Tegan to the Jurassic era, the only danger he faces is when he makes an age joke.

When, after Sarah Jane dies (yeeeears in the future, tyvm), Fourteen takes Luke, Maria, Clyde, and Rani to see Florana—the place he promised to take Sarah Jane all those years ago—the TARDIS chooses the safest, most beautiful moment in time for them to honor her memory.

When Donna and Martha and Yaz and Shirley sneak in for a joyride, they have the time of their lives, and the TARDIS covers for them. (Fourteen suspects, but can't prove it.)

When Fourteen is struggling, and chafing at life on Earth, and just needs to run, to fix things, to solve puzzles, to get away from the day-to-day of it all, the TARDIS lets him. She takes him so many places he's never been before, and they're all beautiful and wild and remind him what he loves about the universe.

(He tries, a few times, to go places that might bring him pain, and she gently refuses.)

And every now and then, someone will try to get in. This TARDIS doesn't have a key; she just opens to those in her care, and refuses entry to those she doesn't trust. She is safe, and so are they.

When Donna's in her eighties and can't get around as easily, the TARDIS takes her where she can manage. When Rose is overwhelmed with the pain of the world, the TARDIS takes her to places where none of that pain exists, and lets her stay as long as she needs to.

They live magnificent lives, and the TARDIS takes care of them. And then, at the end of it, Fourteen is ready for what comes next, and he becomes Fifteen. There's only one Doctor again.

But this TARDIS...

I think she stays, right in the corner of that yard. She leaves and then lands so precisely that roots and ivy grow over her. The Doctor is gone, and eventually Mel and Sarah Jane and Jo and Donna and Martha and everyone that traveled with the Doctor once upon a time in a different TARDIS are gone too.

But Rose is still there. Luke, Maria, Rani, and Clyde are still there. Their families, their kids. The TARDIS opens to them, and shows them the universe. She takes them only where she chooses to, and it's always exactly where they need to go.

She always takes them home, to the garden that once belonged to Donna Noble.

The Doctor finds new companions. Some of them come home to Earth after awhile, but they're not stuck dreaming of the universe. You showed me the furthest reaches of the galaxy, Sarah Jane said. You showed me supernovas, intergalactic battles, and then you just dropped me back on Earth. How could anything compare to that? We get a taste of that splendor, but then we have to go back.

These new companions, they return to Earth and their lives there, but every now and then, they swing by that old house that the Noble family has lived in for generations. They say hello to this old/new box, and she invites them in.

They don't have to say goodbye to the universe. She's right there in Chiswick, waiting for them.

And sometimes—on rare occasions, when they need it, or when he (or she, or they) does—she takes them to the Doctor.
