maybe..maybe however there is evidence against kreai being arren also...
There are other things and people the Exile doesn't remember as she did her best to forget anything that would remind her of the wars, like Bao-Dur.
Kae is said to be exiled because of the birth of her child, and Kreia to be exiled for Revan's fall.
As Mical enunciates who Revan's masters were, he's interrupted by Kreia after mentioning Master Kae, as if the next (therefore different) master would be Kreia, who he cannot remember due to her tampering with his mind.
In the cutscenes Mical may just as well be recognizing Kreia and not Kae, though he never calls her by name.
