Why are so many people calling Kinn petty and paranoid over being jealous? Have you seen that damn charmer vampire in their red attire circling around Porsche? Vegas is dangerously handsome! Or did I imagine the ''moments'' Porsche had with him. If Vegas met him first, wouldn't he have wooed him?
Honestly, I haven't seen anyone calling him petty or paranoid. Kinn is jealous and protective because he knows what usually happens in the world he lives in. The fact that Vegas is a sleek bastard who has game and knows how to play nice, if he wants to, doesn't help him when he has to pretend being a hard-ass.
What he doesn't take into account, because he can't, is that Porsche trusts him, not Vegas.
Had Porsche met Vegas first, I think he would have possibly seen him as a buddy, much as he does now and would have rejected him as soon as he made a move. Porsche, in my opinion, only doesn't push Vegas away much quicker, because he knows what the consequences could be after the whole Macau incident. in the end, he still pushes him away and tries fighting him off.
