Think about this - Byron is A calling the shots because he is a sick perv who has a thing for younger women. He has Mona, Ian, Garret, Jason and possibly Ezra working for him. When Ezra goes rogue and dates his own daughter he is desperately trying to get rid of him. He can't do anything drastic for obvious reasons. That's why Aria never gets severely hurt- just troubles with Ezra. Any one else with stronger points to back up this theory? I know it has many loopholes, but think if it were true!
