I know that Josy and Tommy aren't technically related, but sometimes in the Josy/Maya romance playthrough, the family resemblance still shines through. Maybe Monica is her mother's estranged sister or something. Or her dad was fucking Monica for a lot longer than he let on.
My GF hasn’t made it to episode 8 yet, but figured out Jade is Sage’s mom… and has commented more than once about their similar bodies. I haven’t said anything because I don’t wanna spoil Sage’s talk with the MC.
But physical similarities between characters are pretty much entirely because there are a finite number of DAZ elements and customizations, and at some point people are just gonna look alike—and it doesn’t necessarily mean anything. Yes, Tybalt and Rich look alike, but it doesn’t mean they’re meant to be secretly related in the game. Kinda like James Franco and Dave Franco both starring in
The Disaster Artist together, yet playing entirely unrelated guys, resemblance notwithstanding.
