Whoa... Took a look at the dialogue files - seems Obsid has a lot more things planned for the NPCs than there is in the game. For example, not only did they intend for them to be turned to jedis, you were supposed to be able to teach them new force forms and fighting techniques. Oh, and there was supposed to be cutscenes for jedi training, too... Wink, wink.
edit: By the way, is there any combat training with Visas in TSL? There seem to be some references to that in kreia.dlg.
