The key word is "yet", Guy is a new rich building his own network. But with time and lawyers/advisors he can destroy someone like Lucian with just a call like Risa's father can do right now.
This bring one interesting question tho, Why Risa's father hasn't destroyed Lucian yet?
We have seen how his people has a full dossier about Guy deeds because he's been living in one of their buildings and in contact with Risa. So it would be strange if they has nothing on Lucian, one of Risa's dealers since college days.
Can we expect Risa's father to be Epstein 2.0? I only hope the reason is not that Lucian is blackmailing him, because if a small potatoes like Lucian tries to blackmail a millionaire irl he's dead meat. Like imagine trying to blackmail George Soros because you sold him some black market gay porn
