Theron and Satele meet Revan in the Shadow of Revan expansion :)

^ I just watched a video about it and I kinda expected dialogue kinda disappointing. But the thought of them "meeting" is kind of cool I guess.

I think it was mentioned somewhere but I can't remember, yes, she knows she is the descendant of Revan and Bastila

Her last name is Shan of course she knows, their family would have kept that legend
