Probably nothing so nefarious. Evil takes a toll on its minions. Bad diet, no sleep because of his need to constantly lie and collude with evil forces. He knows he’s in trouble and he knows his lies won’t work much longer.
He probably is giving his WH doctor fits about trying to keep him up to snuff, so to speak. I say that’s a good thing. I’ve long believed that if your turn your body over to a doctor for any length of time, he/she will eventually kill you. Especially an oncologist. Souped up rat poison purveyors....
