Well I'm no doctor but Pat probably has narcissistic personality disorder, that would explain the inflated sense of self. There's also something called Anosognosia, where you refuse to believe you have a mental problem. There was something else someone brought up, something that was two words, started with a K or something? It basically was a condition where you couldn't gauge your abilities as applied to the real world, or something like that. You perceive yourself as able to do things virtually impossible. Like say, the ability to forcibly reopen a closed case and re-litigate it pro se when it isn't even the correct courtroom to argue it over, a case that was lost by actual attorneys you hired. Pat actually believes he knows better than the "sharks" he paid $100K to represent him.
I love the photo of him playing with the dinosaur, Nikki has a face that says "Well, I guess this is my life, now. I'm married to a fucking man child"
