Besides the fact that Cin Drallig (as seen above) made a cameo appearance in the last Clone Wars episode, the starter of a four part arc went on to center on Ahsoka and Anakin trying to discover who was behind the bombing of the Jedi Temple. They have gone into the interesting subject of nano-droids, and the anti-Jedi protests. I still wonder, why would Letta purposely fill her husband with a bomb?
The Clone Wars went into being a detective show, which is somewhat unusual for a show centered on epic battles and lightsaber duels. The beginning was a nice homage to Revenge of the Sith, and I hope that the next episodes bring in more suspense and drama, just like any good ol' cops show.
