Unlock Handmaiden as a Jedi Guardian

To make Hainmaiden a Jedi Guardian (Light Side) or Dark Jedi Guardian (Dark Side), talk to her on the Ebon Hawk. Ask her to teach you some moves. After you fight her three times (and WIN all three times), ask her to put some clothes on. She will put on Haindmaidens robes. Ask her about the robes. Then ask Kreia about Handmaidens mother. Then talk to Handmaiden again. If you influence is high enough, and you have told Haindmaiden what the Force feels like, you will be able to teach her the ways of the Force.
