Interestingly enough, she also seems to be the yin counterpart to Yang, not only in the darkness aspect. She seems very calm, to Yang's aggressive. One meaning of yin is also "of the netherworld", which gives an interesting take as well, given her portals and apparrent ability to enter Yang's dreams. Sorry if this seems too obvious, but I can never be sure; some people denied Blake being a Faunus even after The Stray!

I'm not 100% sure Raven is Yang's mother. Given that Yang was asking Junior where she was, it is slightly odd that she thought she could just ask him and he'd know the overall answer. So perhaps the half-sister theory is correct, and Raven is someone who would be the clue Yang needs to find her mother.

I'm kind of torn at the moment, actually. Raven being Yang's mom seems like the likely answer, but it is so easy to make her work as a sister instead.
