He's no doubt a heavy drug user..Meth or crack or coke minus cola. Its why he's agitated,paranoid and no self control.
My theory no.1 of the robbery...could be whats pushing him into high gear. There is no way that insurance company is calmly writing a check for 11 million. He's getting poked to explain a lot.
Psych ward...next is rehab. But,he wont change. Back to no self control asap.
