I wanted to play, but I'm no good at thinking of prompts, so I've resorted to the Random Pairing Generator. It suggested several prompts involving people I don't know, one I liked so much I've kept it for myself, and then:

Captain Yates, Captain Magambo, robots

(On the whole I think I would prefer that you take this simply as a character prompt, without shipping the Captains with each other or either with the robots.)
