What makes this really interesting is that this is the first time that we've actually seen a Trainer on the animé actually training his or her Pokémon. In all previous instances, a new ability just appears out of nowhere, and we have just had to take it as read that Ash or whoever the Trainer is has been working with their Pokémon. This time, we will see exactly how one trains a Pokémon to learn a new move.Originally posted by Murgatroyd
Initiated by Ash, thanks to a suggestion from someone who informed him that the next Gym was Rock-type. And there's some pretty intense training involved in learning the move.
