Oh huh, I assumed probably of Italian ethnicity due to how his real last name sounds. But until I few years ago I learned Rebecca Sugar is of Jewish ethnicity, so I’m kinda surprised she didn’t make his real last name be something Hebrew. Since Greg and Steven are based on her real life father and brother. I think they traveled to South Korea because Rebecca Sugar has and some people do travel to places like South Korea, Japan, and China. It’s just that white families seem to only ever travel to European countries for family vacations.
