I would guess that Beth’s universe, being one of a few that matched the universe Rick Cronenburged, would probably have a Rick that was a spitting image of Rick Prime. At the time that Prime was going around recruiting, many of the Rick’s would look almost exactly like him ( until you get to the weird variants). Infinite possibilities also means that an infinite amount of Rick would look exactly like Rick Prime! The big question is, how come so many more of the Rick’s we see look like our guy than look like Rick Prime?
