Today, IGN released new Season 4 images. They show a new shot of Ahsoka in scuba gear, more pictures from the Mon Cal battle, and apparently, Artoo and Threepio are going to get into a 'little trouble', as there were pictures of them being tied up by six-inch-tall creatures. There is also a shot of Anakin and Padme fighting commando droids.
So, we are going to be seeing more of Padme this season. Personally, I thought we'd seen enough of her last season, but if she's going to be fighting, not debating, then I guess I can live with her.
But why the heck do they have a Senator in the middle of an underwater battle?
