It's genuinely fucked. The simple fact that Nathan has seen his dad sucking dick is already DERANGED.
It's literally the imaginary scenario of the OF mom's son getting bullied in school for his mom being a whore. Except, that this is far worse.
Reminder, that Destiny during a conversation with Dan didn't seem what was so wrong with wanting to take Nathan with his dates with the girls that he flies out.
He's genuinely deranged, ACTUALLY, mentally ill, and he shouldn't be allowed anywhere near his son.
(ACKTUALLY

he was never married to Rachel (Nathan's mom))
