I'm pretty sure that it's pretty obvious if you play through one time as a male that Kreia is Kae and handmaidens mother i mean she hated the fact that handmaiden was on board because she's her daughter and part of he (if not the entire) reason she was expelled from the jedi order, and the whole thing about Revan returning to his first master Kae. Kreia says in the end he returned to me his first master.
There is no Palpatine. No Empire. No Jedi. There is no Light. No Dark... Just you, and I, here, now.
