keep your bad vibes out of my cornflakes

As for Giorno’s inner circle, I also really disagree with phf’s portrayal of Mista’s superstition. No he would not be afraid of being second in command. He is specifically afraid of choosing one thing out of a selection of four things. Like firing one bullet out of a selection of four. Or getting one slice of cake out of a selection of four. Not just the number four in general. And certainly not the number two. I also think that Polnareff wouldn’t want to be officially part of the mafia. Like, he hangs around because he thinks Giorno is a good guy and the only other option is going towards that big boulangerie in the sky but he’s not exactly a gangster. So Mista would have to be Giorno’s right hand man by process of elimination. I think part of the reason you could give for Giorno reaching out to Fugo and giving him a chance could simply be because he literally doesn’t have anyone else in Passione he can trust. His current inner circle is just a guy with a gun so he’ll take all the allies he can get. More on that later though.

As for Trish, I think she would initially try to get as far away from Passione shit as possible, and Giorno and Mista would have no objections. However, you know what they say about stand users attracting each other. And seeing as most of the other stand users in Italy also happen to be Passione members, staying entirely clear of gang business would be very difficult. She also has a real bond with Giorno and Mista just by virtue of going through the same traumatic shit with them, so I think she’d eventually find herself in their vicinity again. There would be a kind of love-hate relationship I think where she thinks they’re the only people that understand her situation but she also kind views it as their fault that she still has to deal with stand/mafia bullshit.

Fugo would eventually be added to Giorno’s trusted inner circle, but I don’t think it could expand much further. While we know that Diavolo’s issues started well before he took over Passione, the role of mafia boss inherently comes with a heap of paranoia around rival gangs and backstabbers. Especially with how sudden Giorno’s takeover was. Though honestly, due to Diavolo’s insistence on hiding his identity and impersonal correspondence with subordinates, I doubt that there’s anyone in Passione who was all that loyal to him as a person. I think that over the first few months as boss Giorno would grow more and more aware of exactly what he got himself into, and would start to experience a lot of stress and paranoia. Eventually though he would get the hang of things.
