While heading to the Unova League location across a field of tall grass, Ash and co. are stopped by the twins name Soran who has a Braviary and Rocko who has a Dilbur. Apparently, they challenge them to a tag battle. So Ash and Cilan participate in this tag battle against the twins with Ash's Unfezant and Cilan's Pansage and beat them with their combo moves they've come up. Now that Ash and Cilan wins this, it appears that Soran and Rocko had something to be missing in common due to the fact that Cilan suggests that they need to be the rulers of water by catching Water-type Pokemons. Will Cilan's advice on how to find other options help the twins by catching Water-type Pokemons? Yes.
