Episode plot

Serena, a young girl from Vaniville Town, is learning how to ride her mother's Rhyhorn, but instead, the Rhyhorn is jumping around, throwing her around like it's in a rodeo. Her mother gives her pointers, but unfortunately, she ends up getting thrown to the ground, getting scratches on her face when she lands. She exclaims at this terrible experience.

Meanwhile, in Lumiose City, Ash, Clemont, and Bonnie run as fast as they can to Professor Sycamore's lab with the injured Froakie. Team Rocket, who got blasted off into a tree, notice Ash and his friends arrive at the lab and plot to steal the Pokémon there, but fall off the branch thanks to Wobbuffet. Once there, Ash and Bonnie are greeted by The professor himself, who apparently woke up from a nap. He suddenly notices Froakie and calls for Sophie, his assistant. He says that it's Trainer had been in contact. Once Sophie arrives, she takes it to get treated. After that he claims that Froakie's Trainer called him and wished to give up Froakie. Clemont arrived soon after. Froakie was placed in a healing chamber and was being treated. Professor Sycamore reassures Ash and co that Froakie will be fine because Sophie is his best assistant. After that, Professor Sycamore introduces himself to Ash and co. and they do the same, and Clemont is honored to meet him. Ash explains that he and Pikachu just got to Lumiose City from Pallet Town. The professor thanks Ash for saving Froakie, but Ash tells him it saved him, Clemont and Bonnie, but wonders why Froakie's old Trainer would give it up. The professor tells them it's his responsibility to give new Pokémon to New Trainers and Froakie is one of those Pokémon but that Froakie doesn't listen to its Trainer during battle, and often runs away from Trainers it doesn't like. This particular Trainer is also just one of many other Trainers that have returned the troublesome water Pokémon back to Sycamore.

Ash is shocked to learn that more than one Trainer has given up Froakie, but the professor says that there has to be a reason Froakie acts this way. Bonnie thinks that Froakie has had a hard life and Clemont has heard rumors about a Trainer's first Pokémon, but thought they were absurd so he didn't believe them. Ash and company soon meet Garchomp, a Pokémon that lives at the lab. Sycamore says that Garchomp "has a good heart". Garchomp was worried about Froakie but the professor reassures it that Froakie will be fine and can thank Ash and his friends for helping it.

Professor Sycamore explains that he is studying Mega Evolution, a new type of evolution available to many fully evolved Pokémon. The mechanics are still a mystery to him but two key factors are that it requires a strong bond between Trainer and Pokémon and a special stone, and that it changes back after Mega Evolving. Jessie, James, and Meowth hear Professor Sycamore from the roof of the greenhouse, and hatch a scheme. They disguise as scientists and enter the lab. Sophie confronts Team Rocket. Meanwhile, Froakie is fully healed and decides to investigate. They claim to be of service to Professor Sycamore, Cosette and Garchomp arrive soon after, while Sophie claims she had not heard any of this, and Cosette leaves to get Professor Sycamore.

James tries to regain control but it's no use. The others soon arrive.

Ash gives an explanation as to who they are and as they boast, Garchomp fires Hyper Beam sending Team Rocket blasting off. However, Garchomp is still suffering.
