my thoughts re: trish's arc rn are primarily centered around the bruno team because. there's some guilt there. she might not admit it if prompted or accused but like. three people died for her sake. also to kill the boss but like-- she was . the inciting factor
and also i think she cares abt them a lot but outside of the ark, she absolutely feels like she cant be close friends with gio or mista despite liking them because. she didn't get to choose anything abt her involvement in passione infighting.
so since she can't separate herself from the fact that she's The Old Boss' Daughter she at least wants to separate herself from current passione. she keeps in touch but it's distant. but on the ark, not nearly as much risk involved, nobody else she knows is there
except for. yknow. diavolo. so. lots of reasons to stick around bucci gang. not nearly as many not to. she can hang out with them outside of "we are fucking under attack" mode
outside of brunos trans youth group i think she just needs friends her age in general. needs to get to be confident and cool and have normal teen pop star problems. maybe have someone to look up to who isn't an organized crime dude (no shade to bruno or gio)
