Her masters believed that Padawans best learned through first hand experience. They wished her to learn compassion amongst the destruction on the planet Taris, and to exorcise a dark sided ghost from some ancient jedi ruins.
After an interesting sequence of events involving binding the ghost of her Sith Lord ancestor, I killed her masters and she chose to follow me rather than return to the Jedi in disgrace.
From what I can tell, she hopes to find a way to bridge the distance between Sith, and Jedi. I am curious to see her try.
