Ex Post Facto

Suppose we receive our first visit on Earth from travelers from a planet Banea in the delta quadrant. Do they then go with a professor to his house to have dinner with his wife ("honey, I have two guests from Banea visiting" "why didn't you call?")?

Suppose you are 70,000 light years from home, your spacecraft breaks down and miraculously you find a planet where Baneans live who - despite the fact that they are at war with their neighbors - are willing to help you. As captain of the ship, you send an ensign and a lieutenant. If that lieutenant loses interest after just an hour of talking about the repairs and, out of boredom, follows his baser urges and makes out with the wife of his host, then I don't think it would take a murder to give that lieutenant another job in the future....
