"We start off with the battle between Diantha and Malva, but clearly the writers are more fond of the fire lady. Talonflame dodges Gardevoir's Charge Beam with a Razor Wind, and counters with an Acrobatics, leaving it injured. Malva states that her Talonflame is burning with excitement, and so is herself. Trevor is being ambushed by Bryony's Bisharp, but Croaky protected him with Mat Block and Trevor is overjoyed that Y left Greninja behind to assist him. Meanwhile, Alexa and Viola are dicussing about the Ultimate Weapon which has the ability to zap people and Pokemon of their life forces. Alexa said on their current day, the war ended exactly 3000 years ago, but she gets an ominous feeling.
At the Pokemon Village, Lysandre gets Emma to command a Dragon Pulse from Zygarde, and floors Blaine and Mewtwo. X tries to stop Emma, but Emma says it is her job and she will be rewarded a salary which can help out Cassius. X recalls what Emma previously said about liking Cassius and not being afraid of him, and that she had no talent in helping him with the storage system. X states that until now, he is still fearful of adults and strangers, which was why he refused to leave the house. Without any dreams or targets, he felt like he had no purpose in life and thus went into seclusion for 5 years, until Xerneas and Yveltal destroyed Vaniville. It was only after he set out on a journey and being constantly chased by Team Flare that he realized that he actually had everything, a home, a room, food, friends and Pokemon. Having met so many people on his journey, he saw how many selflessly helped them, and thinks Emma can relate. He thinks that there is nothing more painful than being betrayed by a trusted one, and his words apparently get to Emma.
When Lysandre commands another attack, Emma starts to resist, and Cassius shows up, telling her that she needs not continue with this job. Lysandre gets angry and continues to command her, and Cassius counters by having Gourgeist destroy the commanding device with a Shadow Ball. This seems to truly free Emma, and she commands an attack to Lysandre, but Mega Gyarados chomps on her (honestly this should have killed her) and Zygarde's Pokeball gets taken over by Lysandre. While Zygarde hits X, Cassius and Emma with another Land's Wrath, Y gets Absol to bite on Lysandre's hand, ripping the Mega Ring off his finger (I think his finger remains intact despite the bloody scene) and effectively turning off Gyarados's Mega state. Pyroar attacked Absol with a Noble Roar powered up bite in between but Absol still succeeds.
Meanwhile, Chalmers reports to Lysandre that the bioenergy extraction procedure is set to go, and Lysandre broadcasts his message of world purification via his Holo Caster. Alexa and Viola gets joined by some mysterious people.
Back at the Village, Emma and Cassius survive, but Green and Blaine have already been knocked out. X sees Diantha's Keystone with Green, and recalls what Green said about the Keystones being activated one per one in battle. He gathers the Keystones of Diantha, Green, himself, Y and Korrina (the one they snatched back from Lysandre), and decides to try something. On Route 10, the captured Village Pokemon get their bioenergy zapped, and while the Admins find the scene terrible, Delphox seems unfazed, and the Admins think it resembles the personality of Malva. Team Flare has sent out troops of Venomoths and Amoongusses to keep intruders away with Sleep Powder.
At the Village, X Mega Evolves all 5 of his Pokemon at the same time, and Lysandre is impressed. However, he thinks it is a waste and hits Salame with Dragon Pulse. Fortunately, it was weakened by Sylveon's Misty Terrain, and Kang retaliates with an Outrage. Back on Route 10, the admins note that they have intruders and Delphox attacks with its flames, but it ends up creating an explosion. Turns out, Clemont, Bonnie, Alexa, Viola, Yvette have arrived, and the Vivillon's Powder has caused the explosion with Delphox's flames..."
