Ep 9. Clemont's Got A Secret
Ash and his friends continue their journey through the Kalos region, and this time they meet up with their friend Clemont's sister, Bonnie. She tells them that Clemont has been acting strange lately and that she thinks he might be keeping a secret from them.
As they travel together, they encounter a group of wild Pokemon that have been causing trouble in the area. Clemont disappears while they're trying to capture them, and the others soon realize that he's gone off to deal with the problem by himself.
They eventually find him battling the wild Pokemon with his own inventions, which include a small robot he's built and an electric-powered bike. However, things quickly turn dangerous when the group discovers that the wild Pokemon are actually under the control of Team Rocket.
Clemont reveals that he's been secretly working on a new invention that could stop Team Rocket once and for all, but he's been keeping it a secret because he's afraid it might not work. With Ash and the others by his side, Clemont summons the courage to put his invention to the test.
In a thrilling showdown, they confront Team Rocket and their leader Jessie. With Clemont's new invention and the help of their Pokemon, they manage to defeat them and save the day.
In the end, Clemont opens up to his friends and reveals that he's been struggling with doubts about his abilities as a gym leader. But with their support, he gains the confidence he needs to continue on his journey to become the strongest Pokemon trainer he can be.
