Here I come with more explanations, lol~
Alright, I assume the first part with the boss and Shadow was alright? He practically let them catch him so Enzo's men wouldn't look deeper into the company or get wind of them already making a deal. Now, let's move on to Rian and Enzo's part, hoho!
It's a honey trap, guys. Vulture's boss was practically bragging about Rian's sharp skills (and they're too sharp, damn it), while talking about how nice it would be to have some hard evidence. Well, they have that footage against the Consortium members and Fletcher, but the more, the merrier, right? And they really need something to tie Enzo to the murders, money laundering, and everything else.
I’m not sure how Rian intends to do it... maybe wearing a wire? That turtleneck was bizarre, but his style is always whatever, so who knows. Anyway, he's setting a trap, presenting it as a deal that if Enzo cooperates, he wouldn’t have to lose everything, including both Shine Media and his ties to the Outfit, while he made it ambiguous enough to be even sexually suggestive. But anyway, Enzo knows it's a trap, and Rian probably knows that he knows, but who cares if he's not gonna back off, right? Haha, seriously, this is ╮( ̄▽ ̄)╭
And the reason that Enzo got excited was that Rian had already started his move while still locked up. He used the names of the movies/series from Enzo's watchlist (remember the tablet Enzo told him to use if he was bored?) to send him the location of the trap he’s luring him into! Haha, and he called him 'idiota master' the same way ε=ε=(ノ≧∇≦)ノ these dramatic fools!
But wow, Enzo is crazy! Just stop it, haha... I can’t with him looking like that!
Well, it was supposed to be a simple honey trap. Rian was going to approach Enzo, the same way he approached Fletcher, to gather the base data to do an infiltration into the Consortium and steal their information.
But then Enzo didn't bite, and Rian just kept going because of his pride. And he was lucky/unlucky that something (supposedly) happened to the real Connector, whom Enzo was going to meet, but didn't know his face.
And after that, it's just a circus, really, haha. Rian successfully steals the information (the chip/Umbra project), but then Enzo kills everyone, and makes it impossible to sell the data at that point. By then, Enzo wants to keep him close because he's obsessed, and Rian wants to stay close to figure out the mystery.
Enzo tells Rian later that he intended to kill those guys anyway, and Fletcher says that Enzo gathered them (Consortium members) since they had originally betrayed the Outfit and had stolen their assets from the organization. She said that Enzo's trying to gain power within the Outfit (meaning that he would give the money back to the mafia), which seems unlikely. It seems like he's actually going after the Outfit and is trying to destroy it... for whatever reason.

I'm really ashamed to ask but can someone explain to me what's going on ( ̄∇ ̄")? I must be really dumb but I really can't seem to understand the plot... (help me pls )
