His having a seizure, and then blaming it on his parents who have been in the grave for 40 yrs.
His having a seizure and saying it was because he didn't take enough of a med when in reality it could have been because he took to much oxy or something else.
His having a seizure minutes before putting son in the car to bring him home, and then sit at the hospital after the seizure and tell pastor he would never be able to live with himself if something happened to son. Son saw dad on the ground (thankfully not the seizure part) and saw the ambulance take him away. Son was in tears.
