[Chimaera182]

Once you've made all the companions who can be Jedi Jedi, there's not much point in influencing them further. The influence thing for them was basically so you'd be able to make them Jedi anyway, and once you've got that, they're done. Most of what Handmaiden will tell you about Atris she does as soon as you get her. Anything else usually comes before you are able to train her as a Jedi. As for Kreia, I don't think there's much after that. She tells you how she was cast down and exiled, stripped of her own power. She tells you about Revan. But most of your conversations with her tend to be there to give you more power, and those--at least the one where you choose your Jedi class--are more light/dark side-based or level-based than based on influence.
