X Mega Evolves Kanga and Li'l Kanga to battle the Lumiose Press editor-in-chief's Pangoro, as they start battling, X notices that the Pokémon from downstairs have come upstairs because they heard the ruckus. Kanga and Li'l Kanga are having trouble attacking Pangoro, as it keeps successfully predicting their moves, so X checks his Pokédex and finds the answer. X then wants Salamè to attack Pangoro, but it's too busy with the Lumiose Press editor-in-chief's Spewpa, so X commands Marisso to help Salamè, but it's busy attacking the other Spewpa. Y, Tierno, Shauna and Alexa are hearing the battle from the bottom floor of Prism Tower, Alexa wonders if X will be able to win the battle by himself, and Tierno and Shauna tell her that X will have a harder time winning if they were hanging around. Shauna asks Alexa if Professor Sycamore is still in Prism Tower, and she says that he left after the interview with the editor-in-chief, Y says that when X wins they have to go to Sycamore's Lab to talk with him. However, Tierno and Shauna don't want to go there because they believe almost everyone in the city is their enemy.
Back at the battle, X questions why Marisso and Salamè aren't listening to him, the Lumiose Press editor-in-chief tells him that it's because of Spewpa's Rage Powder, which makes the two can't take their eyes off Spewpa. Marisso and Salamè finally defeat the two Spewpa, but they're too tired to continue fighting, so Pangoro grabs the two and tries to crush them. X tells Salamè to let go of its tail, burning the leaf in Pangoro's mouth, Kanga and Li'l Kanga go to attack Pangoro and finally land a hit on it. Pangoro lets go of Marisso and Salamè and the editor-in-chief questions how X knew Pangoro's secret, X reveals he got it from reading Pangoro's Pokédex entry. It says that Pangoro uses the leaf in its mouth to know what move its opponent uses, so with its leaf gone, Pangoro's useless.
Kanga and Li'l Kanga punch Pangoro out a glass window, fainting it, with an Electrike watching it. However the editor-in-chief still has Alexa's Helioptile, which he stole earlier, but the broken glass Pangoro fell out of lets the sun come into the room, allowing Helioptile to recharge its energy and electrocute the editor-in-chief. Helioptile reunites with Alexa, who gives the group an article written three years ago before she leaves, Trevor then wakes up and Y tells him that there leaving the city. Trevor doesn't want to leave because he has to talk with Professor Sycamore, but X reveals that he talked with Sycamore about the Pokémon that attacked Vaniville Town, Sycamore said that the Pokémon with antlers is Xerneas and the Pokémon with wings is Yveltal.
