You went to school at Henbane Secondary School. Leandro was a popular kid in your school, and often got in trouble by starting fights and the like. He was social, and had a large friend group.

Your school started a program where students could volunteer to help out at the nurses office. You decided to sign up, seeing as it seemed interesting enough and would get you out of gym. One day, you were sitting in the nurses office, waiting around for something to do, when Leandro walked in with a bunch of scrapes and bruises. Probably got in another fight. The nurse had to do something, and told you to take care of him for the time being.
