Maryse looked up at her two sons and sighed. "Boys… You know angels are real, Jace has even seen one. You probably didn't know that there are two types of Nephilim. Us, the shadow hunters, and true Nephilim. true Nephilim are the children of angels and humans. Each Nephilim is assigned a shadow hunter when they turn eighteen. They look over the shadow hunter and if they're deemed acceptable after a year, they become angels." She breathed and stated "You have been assigned John and Angelus Winchester."
