User blog comment:Zathronas/Speculative author, Volume 3: Yang Xiao Long/@comment-25258408-20141115230400

I can't say I'm totally sold on Yang actually leaving, but the more I think about it the more sense it makes, and it also seems like it might be good for her. After all, her main role in the plot (search for her mom) completely separates her from the rest of the team. Also, if your speculation turns out to be right, Yang will be far more involved in the main plot than she ever was; she's the only main character so far with no connections (Blake to the WF, Weiss to the SDC, although we don't know if her family's company is just morally gray or if they crossed that line) or reasons (Ruby's desire to help others) to get involved.

It would also be really cool if something similar to what you described does happen; Yang finds that Raven isn't the person she thought she was, similar to (I assume) what happened to Blake and Adam. It would be especially devastating if Raven turned out to be her mom.
