Once again, no one has yet made an Episode Discussion thread for this episode, so I decided to take the initiative.
Personally, I thought it was an awesome episode. Not only did we get to see Ash defeat Clay and win his fifth Unova Gym Badge, but we also got to see another one of Ash's Pokemon evolve during a Gym Battle, just like his Sewaddle evolved into Swadloon during his battle with Burgh. This time, it was his Roggenrola, which evolved into Boldore during its battle with Clay's Excadrill. Anyway, what did you guys think of the episode?
