Sadly, Tarzan met Tublat for the last time, as he went too drunk on him so the son was preparing to grapple him with his hands. The father showed a lot of drunken and rabid behaviour, as well as both physical and mental health issues, which all indicate that he'd been raped by fellow apes for a long time. Not even his ultimately much caring mother figure and Tarzan's granny figure Mi could save him from a lifetime of screwed up shit, nor were his birth parents.
