elysia

I'm in Korriban right now, and I'm stuck in the secret tomb in the shyrack's cave. I'm at the part where I run into 'Kreia', and then the rest of my party members comes in. I am becoming a Jedi master, and I was wondering what I had to say to Kreia in order to stay on the light side, because everytime I go through this part, they begin to fight me, I lose, and I gain dark side points. Can anyone help me out? I'm completely stuck.
