After meeting Burgh and catching a Sewaddle, Ash and co. take a stop at a Poké Mart to stock up on supplies. There Ash learns more about Pokémon Connoisseurs and waits in line to get his compatibility tested. He is then pulled into a shop by a girl named Burgundy who thinks herself as an S-Class Pokemon Connoisseusse. However, as Burgundy check all of Ash's Pokemons, she says that all of his Pokémon are horrible just because they attacked her because they think Ash is a great Trainer even though she doesn't think so. Iris and Cilan find Ash and Burgundy, who apparently has an axe to grind to get her revenge with Cilan for beating her at the Striaton Gym assuming that his words are very hurtful. Not only that, Burgundy also lied when she's "actually" not an S-Class because she's a C-Class Connoisseusse. Who will win the rematch?
When Ash, Iris and Cilan enter the Mart, they see all kinds of merchandise. Ash spots a group of people waiting. Cilan explains it is due to Connoisseusse - people who give advise how to bond with their Pokemon better.
Ash is waiting in the line, while a person speaks to him behind a curtain. She addresses herself as Burgundy. She first examines Ash's Pokemon - Tepig, Oshawott, Snivy, Scraggy, even Pickachu. As she makes her suggestion, each Pokemon becomes angry and attcks her. Burgundy becomes furious and advises Ash to change all his Pokemon, to which he, naturally, denies.
Cilan enters the room and Burgundy becomes even more furious, as she thinks Cilan is much more superior. She tells her tale that she battled with Cilan once and she lost. Then she got the license to become a Pokemon Connoisseusser, but (according to her) Cilan is better in that expertise. She wanted to challenge Cilan to a fight, but Cilan's brothers said that he was gone. Bugurundy then shows her badge she got from the Gym fight in Striaton City. Bugrundy then challenges Cilan to a fight.
Cilan brings Dwebble, while Bugrundy brings her Dewott out. Dewott attacks with Water Pulse, Water Gun and Razor Shell attcks, to which Dwebble resists using Protect move. Dwebble then attacks with Slash move, defeating Dewott.
Bugrundy then sends Sawsbuck, while Cilan sends his favourite Pansage out to fight. While Sawsbuck makes his first move, Pansage makes the counter move, Dig, to defeat Sawsbuck. In the end, Burgundy leaves, promising to fight Cilan once more.
