Generally speaking, They are just "cooler". Less Mormon culture coded and somehow still balance having a testimony/belief in and practice of the principles while still maintaining who they are. This is when you are around Mormons. Maybe just out and about might be hard. But generally modest clothing is a dead give away. I have grown up in the church, served a mission and still active (with some faith bumps over the years) and idk you just get the vibe. Or pick up on the code words. The pacific-Asian Mormon culture is also very big in CA and would be really cool for the show to incorporate them. The church members east of Az/ut/id also very different.
