While we've already gotten the preview write-up and video clip, the preview version of the episode guide for "Sphere of Influence" (S3 Ep. 4) is now online at the main site with the following synopsis:
"Chairman Papanoida's family is kidnapped and held for ransom. Ahsoka must team up with the Senator from Pantora, Riyo Chuchi, to aid the new chairman in recovering his family before the Trade Federation can unduly influence the future of his planet."
By way of the preview, we're reminded that Chairman Papanoida is the character played by George Lucas himself in Revenge of the Sith. It should also be noted that George's daughter, Katie Lucas, co-wrote this episode with Steven Melching. As always, we'll update when the full episode guide goes online.
UPDATE: The full version of the episode guide for "Sphere of Influence" (S3 Ep. 4) is now online at the main site with video commentary.
