From foes to friends

"So.. You have any members of your family around town, Aaron?"
"Yeah, just not alive you know haha"
"Oh.. I'm sorry"
"Is fine. I was the one who murder them anyways!"
"You did what?!"
"Calm down, let me explain. My father and mother were the original owners of the mafia, however, they were REALLY disrespectful with they own partners. I find that disgusting, so I shot down my mother and dropkick my father from the top of the bulding's window. I become the new boss and started everything from the beginning"
"... You, miss them?"
"Ha, no! The mafia is my new family. Why bother about them anymore?"
"Yeah.. I guess you got an point..."

(Canonically, Max and the mafia boss become friends at some point )
