The Outsiders, the most known mafia crew in town other than The Riches (Socs). They were known for their close bond, the way the work, and their long list of crimes.
It was the Curtis brother's father who started this mafia crew, but once he, and their mother died, it was pass on to Darry to look after. Even if Darry is only twenty, he's a damn good mobster boss.
Sodapop deals with the press, and unwanted visitors being the most socialble, and charming looking. Two-Bit, and Steve handle making sure people are disposed of correctly. Dally takes care of people. Ponyboy, and Johnny are just kinda there since they're only fourteen and sixteen. Darry handles everything else.
Though, it wasn't long til Darry was concerned on needing more help handling those other mobsters, and taking people out.
