I liked the backstory about Aaron and his Waumpel. The same thing happened almost to Hikari when she released Pachirisu, but unlike Aaron, she got it back immediately. Poor Aaron...his character was not that bad. I like him and it sucks that he got stuck with bad animation. The next episode will be a Kinoshita one, so his battle against Cynthia will be, once again, bad animated.
Too bad, really, because the animation made his pokemon look like semi-powerful pokemon. NO force or power behind their attacks, just bland stills. But it wasn´t the animation alone. I don´t get why Beequeen and Drapion looked and acted so weak in this episode. He is supposed to be a Elite 4 member, but he seemed like a bug loving random guy... :/
I also liked the flashback to Caterpie/Butterfree. The goodbye scene looked nice, and that in a Takeda episode ^^
EDIT: I forgot the honey-tree scene. Like the digging underground concept, the honey trees from the games were kinda featured in this episode by Team Rocket. And they found Gonbe that way. Kinda ironically because it is hard as hell to find one in the trees. Reminded me of the Whiscash episode when Jessie kept bumbing into Feebas.
When was the last time weve seen Beedrill?
