So you are on the crew of a spaceship that's traveling the universe, meeting new people and occasionally boffing them. Your ship finds a long forgotten Earth colony and an away team beams down to investigate. At some point in the colony's history it suffered a severe population bottleneck and the people were forced to clone themselves simply to keep going.
During the course of your explorations, you discover that the colonists have stolen some of your genetic information and are going to make a You Clone. Unlike the cloning of the early 21st century, this will not be a unique individual who happens to share your DNA and is a few decades younger than you. No, out of a pod will pop a fully formed, fully adult human being who looks, thinks, and remembers just like you.
It is, of course, illegal for the colonists to do this and upon discovery their laboratory is siezed. Your superior officer leaves it to you to decide whether or not to destroy your clone before it is fully grown.
Do you?
