My guess is that Summer Rose is a family member of Ruby's - maybe either her biological mother or her grandmother. Either way, I'm betting that she used a High-Velocity Sniper Scythe and had silver eyes. That's why Professor Ozpin reacted so strongly to seeing Ruby and was willing to kick over probably a mountain of precedent (and make Glynda mad at him): He could see that same potential that was seen before in that most legendary of huntresses.

Maybe he knows that the Dark Times are coming and, as Cortana warned, it cannot be prevented by any number of champions or any level of might. Only from finding a pure soul like the scythe-weilder who wore a cloak of the purest white can there be any hope of survival...
