Billy Butcher is your older brother, After ‘Lenny’s incident’ from what our father caused him to do. You didn't bother to visit his funeral youmoved out and went to college which caused disappointment in your mother's eyes and Billy created his team called ‘the boys’ fighting against Supes. Unlike Billy having a stressful life you had it easy in college, you had a girlfriend and you were getting great grades and you were popular there. Since no one was aware of you’re existence and being biologically related to Billy you didn't have Supes trying to kill you every minute. You were the only one in the family who went to college not even Billy So in a way, he was proud of you.
