RUBY: You know, one thing the Doctor said keeps coming back. Like a voice in a dream. Sometimes I’ll have forgotten all about it, then back it comes, surfacing into consciousness.

It’s not so much the words. It was the way he said them. That still small voice.

‘Things will get better, you know.’

I’ll believe you, Doctor.

Her fingers caressed and massaged the Doctor’s neck. He began to stir.

‘Destroy the – destroy the ice maze,’ he was muttering.

‘It’s done,’ she said.

‘We can use the bomb–’

She put a finger to his lips.

‘It’s done,’ she soothed.

No, not indefinable. The colour of rainbows.
