His plan - before Korea - was obviously "tiny Maltese island where I can hide and be rich and get the fuck out of the mafia"
But then he met Yu Chan and it changed a little to "tiny Maltese island where I can hide and be rich and GTFO of the mafia but it'll be named as an homage to Hong Yu Chan"
And THEN he got inducted into the Geumga tenants and saw what happened to his birth mother and the Babel victims and it became "tiny Maltese island named as an homage to Hong Yu Chan where I can hide and be rich but provide refuge to people who need it where I will work to GTFO of the mafia, hopefully without creating too many refugees for me to house on said island in the process"
Which, by the end, had shifted all the way to "tiny Maltese refuge island named as an homage to Yu Chan where I will, well, okay, run the mafia but still hide from everyone minus very specific people I feel deserve to go there which absolutely includes the woman who is in physical possession of the money which makes me rich who happens to have her own quarters on said island as well as an open invitation to visit anytime"
Vinny's evolution from the "fuck all y'all" brand of rich hermit to the "fuck most of y'all but some of you are okay and one of you is very, very okay" brand of rich hermit is a favorite.
