Don't own Doctor Who, probably never will.
The title is taken from Act 2, Scene 2 of Hamlet by William Shakespeare.
A Goodly Prison
This world was a prison, had been since the moment she stood on one side of that damn wall and felt him slip away on the other.
This world was empty and bleak and dull. There was no Doctor, no TARDIS, no hand to hold; only Torchwood, her parents and Mickey to fill the void here.
But it wasn't enough. It would never be enough.
She was alone, and it would slowly kill her, of that she was sure.
And so she came back, blasting her way through other dimensions, all to look for him.
And then he left her here again.
And it hurt again, and she broke again and again and again, always breaking because of him.
But he was worth it. The Doctor would always be worth it.
And he had given her the greatest gift in the entire universe.
The words he had once been so hesitant to say became a mantra, always repeated in their lives, whispered, shouted, cried; accompanied by laughs, smiles, sobs, even the occasional snarl.
Yes, this world was still a prison, she was still trapped, the walls of this universe pressing in around her, and, yes, she still hated it.
But still…it was better with two.
