"Then you mean you won't come back to Earth with us?" Purcell asked later, in the spaceship.
"Not if all you say about this world is true," Charlie said. "We're needed here."
"Yes," Purcell agreed. "With your help, the galaxy could be made into a universe of plenty for everyone."
"Besides," said Robin. "We'll have to think of training children to take over after we're gone." She looked at Charlie. She blushed. "Such as our own," she said, very quickly, and added: "You can marry us, can't you, Captain?"
Purcell beamed, and nodded, and did so.
Later, Charlie said: "It isn't only that we're needed here, is it, darling?"
Robin shook her head. "We like it here," she said.
