who acts like their most authentic selves?

On rewatch #3 rn and my opinion on who shows their most authentic self vs. who puts up a front/fake persona for the cameras:

Most Authentic:

-James, Kristen

honorable mentions: Raquel, Katie

Most fake:

-Schwartz, Brattney (literally is a character on season 8 compared to her introduction with her hyuck hyuck laugh after every single thing and fake healthy relationship)

honorable mentions: Jax, Lala

I believe a majority of the cast fall somewhere between, but lmk what you guys think
