JONAS BROTHERS MAFIA AU.
This makes me want to read Mafia AU something fierce. They're all brothers, right, so it's perfect! And their father would be the mob boss, and they'd be Little Nicky, Joey "Danger" and Paulie Jr. (because Kevin isn't a very Mafia name). Frankie would be the baby, just like Frankie Gotti in "Growing Up Gotti" (lol). Little Nicky could be ~intensely planning a power play to try to overthrow his father, and Paulie Jr. would be all ~loyal to his father on account of being his namesake and everything, and Joey "Danger" would be ~conflicted but ultimately decide to side with Nick, thus tearing the family apart. Somebody please write this.
