Maybe, but then again, maybe not. I think that Brianna has no idea that Kreia is her mother, or surely she would have said something. Brianna seems to respect her mother and I'm sure is she was aware that her mother was vstaying in the same ship, there would have been some communication at least.
What is intesting is that through the whole game, Handmaiden and Kreia have very little contact on the Hawk. There are scenes of her and Atton, Disciple, but no HM. Interesting...
