I just finish watching the episode, I actually like it, too bad I don't understand what they're saying. I wonder why Dento/Cilan told Ash to use Roggenrola for. And the two new psychic pokemon looks cute. I'm just sad that I didn't see yanappu/Pansage in this episode(since he's my favorite Pokemon, I just hope they show him every episode). But still I like how Cilan introduce himself to TR when he found them.
Not that I speak Japanese but knowing what Roggenrola is,Cilan probably figured that Roggenrola could hear extremely well, and would be able to track the Audino.
