TARDIS INTERNAL CAMS 3

The Doctor and Castiel get along swimmingly.

They shouldn't do, but who cares?

They are planning. Castiel can't get back to his world by himself, and the Doctor can't fly the TARDIS into another universe just like that. It would never work.

Their shared genius is astounding, really. They know so much between the two of them and it won't take long to figure out how to get Clara back and bring Cas home.

So they brainstorm. For hours and hours and hours they sit on the floor of the console room tossing ideas into the thin sliver of air between them. They debate everything.

Then the Doctor comes up with something brilliant.

He pirouettes around the room like a madman, his ridiculous hair bouncing. He sets his course for Cardiff, Wales as a pitstop, and his grin takes up the whole of his rectangular face.

Cas is thoroughly confused. What is so important about a city in Wales?

A couple of minutes later, the TARDIS' engines are full and Cas understands. The Doctor wants Castiel to lend some of his grace to the TARDIS, which will give her enough residual energy to get them across the Void and into Castiel's universe.

Castiel is very, very unsure and possibly unwilling, but the Doctor is a genius. Though he's not sure why, he trusts the alien man with his life. The only other person he would ever trust like that is Dean and he's not one to hold his heart in his hands.

They land in Cardiff, the Doctor weaving a complicated dance around his beloved machine. Cas is still sitting on the blue metal ground, breathing the air of a different universe and hoping he'll get back soon. He's not one to get stuck places. He's a gust of wind in an oceanic storm, a raven with wings spread. Always escaping, always flying away... He doesn't notice when they take off again until the Doctor tells him.

He then also tells Cas what to do.

"So, Castiel, in order to merge your grace with the TARDIS' sentience, we'll have to open..." The Doctor yanks on the edge of the console. "This. Well, it's supposed to open."

Cas pushes him aside and easily opens the hatch.

But everything goes white and gold. Cas sees time itself and everything that could happen and the entire universe is whizzing about in his head.

He shivers and his hands stiffen. He contracts in pain but still stands, wanting and hoping.

Universe. A universe alight. Power, so MUCH power. More than before. More than an angel, more than a God. Galaxies exploding, Earth and Heaven rising, Hell crushed and blinded by light. Sun, Moon, Stars, Dean, TARDIS, Milky Way, Sam, Doctor, Seven Systems of Kasterborous, Lucifer, Pluto, Dean, TARDIS, time...

Cas is in control.

The walls of worlds crack and shatter.

They fly.
