If Elio was a girl, would his dad have had the same reaction?
I lost my $h!t at the dad being so cool with the affair. His underage son is a statutory rape victim and the only reason I can think of that he's so chill is that it's a boy.
Imagine if he had a daughter who was getting banged in his own house by a man he invited into his home. Would he be so accommodating? I think not.
