Jimmy Brennen was the abusive father of Cody Brennen.
Jimmy loudly argued with Cody when she briefly entered the house to retrieve some money that she had accidentally left behind. (The Escape Artist)
Jimmy entered the house for a few moments, scaring Cody and her friend Norman Bates, who hid in a closet. Hearing Jimmy made Norman recall bad memories about his own father, Sam Bates. Jimmy then left.
Later, after finding out that Cody had told Emma about his blackouts, Norman called to Cody's house and shouted at her, but she asked him to be quiet because Jimmy was asleep in a nearby room. Jimmy woke up, put Cody in a headlock, and shoved Norman away. Norman managed to push Jimmy down a flight of stairs, saving Cody but killing her father. (Plunge)
