The preview version of the episode guide for "Heroes on Both Sides" (S3 Ep. 10) is now online at the main site with the following synopsis:
"When the Senate begins debate on a bill that would eliminate government oversight of the Banking Clan's activities, Padm? and Ahsoka travel in secret to the capital of the Confederacy of Independent Systems, in an attempt to forge a peace agreement with the Separatists."
We'll be sure to update when the full version of the guide goes online following this week's all-new episode of The Clone Wars.
