Gellar's Facebook page confirms it as well."I may be number 7, but I'm pretty much number 1," Gellar quips in the intro video. She also reveals exactly what her Inquisitor's mission is. "My character believes that Ahsoka is back, and she's trying to track down Ahsoka, and the Rebels... and kill them all!"
She didn't see the design before she got into the booth; in fact, she said some of her mannerisms and hand movements were brought into the animation later. Of course, her husband Freddie Prinze, Jr. voices Kanan, the Jedi leader of the Rebels crew, and as you can see in the video, that means their characters will be very directly at odds with one another.
The Inquisitors, dark side users who haven't been opened to the secrets of the Sith, had one of their ranks dispatched against the Rebels in season one, eventually dying in battle with the Jedi. That made Darth Vader get involved directly, but while he has other matters to attend to, two new Inquisitors have been sent out for Season 2.
The article includes a video with some clips of said new inquisitor in action. Gellar's voice was barely recognizable to me, but I take that as a good thing- I like actors who can play a variety of roles differently. Nonetheless, I'm a little disappointed- I was sort of hoping she'd be voicing a young Princess Leia. But I'm also curious, since I don't think I've ever really seen Gellar play a villain before (unless you count those Buffy episodes where Faith or the First took on Buffy's appearance).
