he is your adopted son. and its clear Raphael is like a smaller and younger version of him. he lives with his mother in heaven. michael trains him. uriel teaches him angelic history and Raphael his father teaches him medical knowledge. he was two years with you in hell to live with my ex azrael, but he couldn't let go his human medium girl. Abaddon is his uncle. he usually had got a sister but she died in his mother's belly.
