So a boy is found in an abandon shack. He is 13. He is severely injured and taken to a hospital. They search for parents or any relatives and find none. The boy has no clear memories of anyone he might of known or his past and is sent to an orphanage as nobody comes claiming to know the kid. They search for any records of anyone who looks like him who the kid might be and come up with nothing. Most importantly to my question, the boy doesn't even know his own name, and their does anyone. What do they call the boy?
