Crap, I thought this was finally the end of droid arc.
As for the episode itself, this was the best of the arc so far thanks to Gregor, but it still wasn't more than OK to me.
Honestly, as a 100th episode, it kind of pissed me off. It would have been nice to have gotten a 100th episode that focused on the big three (Anakin, Obi-Wan, and Ahsoka), or at least one of them, instead of a bunch of new characters, most of whom no one even likes.
