Pokémon S10 E04 Dawn of a New Era!

"Gotta catch 'em all!"

Ash's attempts at helping Dawn catch Pokémon isn't going too well, and the two begin arguing. Wanting to prove herself to Ash, Dawn challenges a Pokémon bard by the name of Nando to a battle. The two later find out that Nando is skilled and undecided about whether to challenge Gyms or Contests, causing Ash and Dawn to each try and persuade him to challenge their preferred competitions.
