Summary: The Doctor is looking for a new companion.

The Doctor gazed up at the skeleton of the blue whale.

“Magnificent, isn’t it?” a woman said from nearby. “A true leviathan, the largest creature on earth.”

“If you think that’s big, you should see a space whale. Out in space they can grow big enough to build entire cities on. I spent some time on one once. Bit of a tragic story really. It was being tortured when there was no need; it would have happily helped if the people aboard it had just asked.”

“Space whales? Don’t be daft; nothing can live in space!”

“Oh, you’d be surprised!”

The End
