Well, that would be a hell of a way for Yang to permanently quit being a part of the plot. It would make the most sense, since Yang's been the most emotionally betrayed member of the team, and she'd by this point would have trust issues after being abandoned repeatedly (her biological mother doesn't give a damn about her, her step-mother left to go on a mission and died, her partner (for a double whammy) initially doubted she was set-up to ruin their school and team's reputation as well as left her after Yang lost her dominant hand for her, her teammate was taken away, and her own younger sister left after an argument on what is--for all intents a purposes--a SUICIDE MISSION to stop the real bad guys when one of their friends who was arguably the best of them already DIED TRYING THE SAME THING, indirectly taking their uncle with her). So yeah, Ruby and Yang will NOT have as close of a relationship as we'd hope they would, anymore.



I feel that, like you, Ruby and Yang's relationship will be thrown into question come Volume 5. As much as the two have sisterly love, it doesn't change the fact that Team RWBY fell apart and the last conversation Ruby and Yang had was on borderline hostile terms, Yang being too emotionally broken to care about the world where Ruby's attempt to talk to her didn't help and in fact possibly made things WORSE. Furthermore, we have no idea what Yang is exactly planning on going after Ruby for, except she says Ruby is "in so much trouble when [she] finds [her]". Whether Yang plans to rejoin Ruby at Haven Academy, drag Ruby back home where it's safe (as far as Yang knows, but in actuality, no place on Remnant IS safe for Ruby from Cinder's revenge), or just chew Ruby out for leaving the house with only a note as her goodbye, the fact is that Ruby's going to need to regain Yang's trust in order to even consider Yang an ally in the fight against Cinder and Salem. This is where I hope my idea of Ruby going on a bunch of loyalty missions with her teammates and friends will come in, Yang's being trying to help Yang get some closure with Raven and reconciling with Blake. If Ruby succeeds in getting Yang her closure, Yang will permanently stay, and the two can truly rebuild their sisterhood. If Yang doesn't get her closure or worse, Ruby and her relationship deteriorates, that's where I feel this picture could come in.
