I like how the fact that the dad is possibly dying got like 5 posts worth of attention.
i think Mr Jet is on the right path regarding his character. before he seemed like the archetypal villain but with this new twist i can see how he can gain some simpathy and somewhat justify his actions.
my guess is he has some sort of cancer and has recently found out he doesn't have much time. he freaks out because he sees his son is wasting his time and doesn't want to carry on his legacy in business, he has very little time to fix this so he approaches it with some extreme methods.
granted, he's still a shitty dad but what you gonna do? some people just have very low emotional intelligence.
that said, if he was in fact abusing Nicole then he's irredeemable in my eyes. but i'm not so sure as everyone else appears to be about the nature of their relationship. i can see Nicole being very submissive with her partners and it's not out of the realm of possibilities that she liked the dad. she already told us how much she respected/admired him and if you tell her she'll owe you a favor there's this scene which suggests she likes men in control.
so i'm gonna give the benefit of the doubt to Mr Jet because i think he can pull another Selina on us.
