Shadow at Morning wrote: She's clearly just a Faunus who's associated with the White Fang, and happens to be Yang's mother. She looks nothing like a Grimm, and everything like a particularly devoted member of the White Fang, possibly gone rogue. I'll be honest, Rogue WF Member Raven sounds rather likely too. But if she's not rogue, then it wouldn't make much sense that she would threaten Neo, an ally. Sure, you could say she was protecting Yang, but if she's not her mother (As likely as it is, until made canon everything is possible), then I don't see much reason to save someone that is fighting against the WF.

And if she was particularly devoted to the WF, why would she go rogue? Why would such a particularly devoted member of the White Fang try to save one of the people they are fighting agaisnt?

And over all of what you said: What makes you think she's a faunus? The mask, which could have been stolen to infiltrate the train/the WF without being attacked? (Maybe she's the one who gives Qrow the information about Cinder and co.).

In any case, if the Grimm are a corruption like Dragon Age's Darkspawn, then it's possible Raven could be a half-Grimm. Maybe she's RWBY's version of a Grey Warden. And Grey Wardens must abandon their lives and families to do their duty...
