I'm convinced at this point he is going to use a defense like "I have no idea who Brian Costello is and I never hired him to represent me" and try to fuck everything up even more.
Everything what will end this madness would help him. But the fact he is going on points to a real hard personal disorder. Acting like this is on the edge what we can call "normal", no doubt. Except he is really going for such a tricky masterpan. What i doubt. But who can say what happens next?
