It being a bug makes the most sense. I've never come across Jaesa before anyway, so...

Today, after completing "The Nathema Conspiracy" and getting engaged to Theron Shan (something that hasn't changed any of his bio or anything else...?) I received a random email from a Jaesa Willsaam saying that she knows about my new "plaything" and that "accidents could happen" and that I should "keep him away from me[her]". After doing some googling I discovered that she is a Sith companion... I am a Jedi Knight who has never had contact with her before. This email has thrown me... is it some sort of glitch? Does the game now think I'm Sith and know this person? Someone help!?
