Hrm, I just had a thought. If Sun is a half-Faunus, what if he only lived with his Human parent? Like, something happened to his Faunus parent when he was young, so the Faunus parent wasn't around. The Human parent may not have had a very deep and detailed knowledge of Faunus history or may not have realized how important it would be to teach Sun about it, and that would be why he didn't know about how the White Fang got started or anything about Menagerie.

I really hope that we get some actual development and backstory on Sun soon. The show needs to look at him as his own character for once, rather than just "That guy who likes Blake".
