In the LS game, during the final confrontation between the Jedi Masters and Kreia on Dantooine, Kreia tells the Masters she is going to show them what it's like to see the world through the Exile's eyes (or words to that effect) and zaps them. They fall down, deader than dead. Kreia then kneels next to the unconscious Exile and says something to the effect that she understands what happened now: "It was because you were afraid."
I found this dialogue to be rather cryptic. At first, I thought she was referring to the Jedi Masters being afraid of the Exile (which of course they were). When I replayed that scene again, it seems pretty clear Kreia meant that the Exile was afraid. My feeling was that she meant the Exile was afraid to form any more bonds with anyone because Malachor caused her so much pain; hence her 10 year self-imposed (at least according to some of the dialogue) exile.
So, is Kreia saying that the Exile cut herself off from the Force because of that fear? But it seems that being cut off from the Force kills Jedi -- UNLESS the Exile had no Force abilities of her own to begin with -- she was only able to tap into the Force abilities of others from the very beginning. So, instead of cutting herself off from the Force, she only cut herself off from Force users, which would be really lonely, but wouldn't kill her. Wouldn't this also mean that Malachor V didn't cause her "Force-vampirism"?
What do you guys think?
