The Daily Record, a Scottish news outlet, published an interview with Ashley Eckstein yesterday where the voice actress talked about Ahsoka being the lens through which viewers see the Clone Wars erupt, her early fandom and how it changed when she got the part, and what she thinks about Ahsoka's endgame.
Here's an excerpt from Ashley's comments on that last topic:
I've become so invested in this character that even the possibility of something tragic happening to her is very sad. I don't know her outcome so while there are theories and Dave has shared some ideas with me, I just don't know. I know Dave and George Lucas will make the right decision for the overall story.
