He's not necessarily wrong, but I look at Envy as long-term potential. Give her kid a brother or sister, that kind of thing. Lily? Absolutely not. She's just sexytime icing on the cake.
If Bella is a thing, so could Nicole, for sure, MC kinda only fucked with her, but from her interactions on Swyper and at the bar, I also think something more is possible, she really seem to like him, and vice versa.
For Lily, I disagree, I think she can be more than that, she isn't just a blonde bimbo, she's cunning and she knows the MC is the next big thing, that's why she wants to 'associate' with him, kinda. But then she takes care of him at the Pink Rose when he gets hit. Just wonder how far she'll go, she's playing a dangerous game, trying to toy around with Quinn and bypassing Vinny.
Actually, just a theory of mine, both could be in huge trouble because of Lily dealings, Nicole mentions her kid a couple times, if they get busted could see a backstory about her losing her kid or something like that, as for Lily things could get darker...
