my theory: The lady is yang's mother, who left Long to join the white fang. This 'betrayal' broke Long's heart till Ruby's mother came into the picture. Yang's mom always kept her distance but also kept a watchful eye on Yang, to make sure she stayed safe and only entered into the fight with Neo because Yang was going to die. Neo, at the sight of yang's mom nearly shits a brick and retreats, obviously having heard, or seen her in a fight and knew there was no way a battle with her would end well.

I like the idea of it being Yang's mom, not just because of the similarity in eyes, but because the idea that the reason Long was doubly-heartbroken when ruby's mom died was because his first wife LEFT him to join an enemy, or at least a radical faction. Yang's mother, being faunus, felt a moral obligation to help...or alternatively--to weaken them. She could have left Long to fight them on her own, possibly from within their own ranks.

Another possibility is it's a future version of Blake, who's semblance seems to be leaving a shadow of herself elsewhere as she 'teleports' out of the way. With time, and training, that skill could develop [arguably] into a full blown time-travel. Only reason this seems plausible is because she looks more like Blake then she does yang, disregarding glowy eyes.
