He'll likely know Charli and Tony pretty well. I think once Charli figured out his dad is good people, she'd have extended friendliness/hospitality his son's way also. I could see them inviting him over for family dinners and such, although that likely also depends on how close he is with his father.
I also have marzetti, who's a soldier for the Lucchese's. He runs the day to day stuff at his family's restaurant but also basically does anything Tony needs him to do. There's a bit of an age gap between Paul and Enzo, but Paul's pretty affable, so he'd likely be friendly to Enzo if/when they're in the same vicinity.
