While training for their next Showcase, Serena ends up going harsh on Fennekin and Pancham when training doesn't go right, still torn from the loss in her first. Feeling down, she leaves Ash and Bonnie for a while for some alone time. As she walks through the city, she meets a girl who randomly approaches her to talk, and they end up going shopping together before finally having a practice battle against her Delphox and Aromatisse. The question is, who is this mysterious girl?

Finally back in Lumiose City, Ash, Serena and Bonnie meet up with Clemont once again. Ash and Clemont are eager to start their gym match, but as it begins, Officer Jenny arrives to arrest the Clembot. It seems a robot looking just like Clembot is being used around the city to commit crimes. Insisting on Clembot's innocence, it's up to Ash & co. to investigate and clear Clembot of all crimes. Can they do it?
