FWIW, I suspect that Raven's certainty that Qrow is following a false messiah and that this will lead him and everyone with him to disaster will, ultimately, be the reason she joins the group in time for the Battle of Haven. I suspect that Yang will challenge her to join them, not because of any personal attachment to Ozpin's cause but because, firstly, the alternative is letting Salem win and, secondly, she owes it to Summer to save Ruby if she can.
