Really great. I like that.
But I don't think Nicole is an agent, more of an informant. She's almost like the federal government. As an informant, she would be perfect. She might have gotten on the radar of the police through her prostitution, the VIP pass is nothing else, and in exchange for information, she doesn't get arrested. In Nicole's case, this has a special effect because she is a mother and certainly doesn't want to be arrested.
Nicole is not only horny, but also dangerous for the MC. When the MC fucks Nicole/Envy in EP3, we learn in EP4, while the MC is fucking Rose, that Envy's real name is Nicole and that Rose has been talking to Nicole about what happened in the VIP room. Therefore, Jacob may be wrong in EP3 when he says that what happens in the Pink Rose stays in the Pink Rose.
(This saying is odd in that it actually applies to Las Vegas. Who used to work in Las Vegas? Emma. Emma looks like a 40-year-old Josy and has a tattoo of Isabella on her right arm. Is there a stripper pole in Isabella's locked room where Isabella practices pole dancing? This is not to say that Isabella is a secret stripper, as there are many women who do this as a sport. However, it can be misconstrued by guys and that's why she locked that room.)
But Lily could still be in play as an undercover agent because Nicole got the MC number from Lily.
