I'm gonna have to agree. I don't think they got her character right. IF it is her, which I hope it isn't.
"Pure Dark Side Entity" "Loved the Emperor"
Those two alone show that it simply can't be her, no matter what they say. Loving someone so devoted to the force, only looking to empower himself with it?
I shouldn't even have to say anything about the Pure Dark side part, that's just drivel.
