Outside the Dancing Ponyta Inn, X emerges from his tent and angrily demands Li'l Kanga back. He reaches for the plastic tape covering his bracelet and attempts to peel it off, but unfortunately fails to do so after several tries, causing Y to sweatdrop and the Team Flare Scientists to become speechless. Y hollers with an annoyed tone, and forcefully grabs X by his wrist. She then tears off the plastic tape violently, and reveals the seven-coloured stone it is covering.

Aliana gasps that the Mega Ring is going to be activated, and Mable says they should get ready for a Mega Evolution. Trevor, who is looking down from the window on the second floor with Tierno and Shauna, overhears the two terms and wonders what they mean.

X places two fingers over the stone on his bracelet and lets out a roar, which causes the stone to glow intensely. Something inside Kanga's pouch also glows in response, but then to everyone's surprise, nothing happens. Mable laughs that they are feeling nervous over nothing, and Aliana giggles that apparently the boy still could not stably activate Mega Evolution. She grins that they should still take good precaution anyway, and gestures to Diggersby, who hurls Li'l Kanga against the ground and knocks it unconscious with the brutal crash.

X cries out in horror, and wonders why he couldn't redo what he did in Vaniville. The Team Flare Scientists mock at his attempt to hide the Mega Ring with a plastic tape, and Mable snickers that they are able to track him down by the waves emanated by the Key Stone. Before she could say anything else, Alina shushes her, and says they will get into trouble with the boss if they reveal too much. Both women cringe at the thought of their angry boss, and decide to zip their mouths and say no more.

X slumps onto the ground as Y runs up to him, and the girl hollers that he cannot give up after a single failed attempt. She cries that they must think of something else, and turns to Chespin and Froakie for help again. However, she soon realizes that she doesn't really know what kind of Pokemon they are, which makes it impossible for her to fight with them. At that moment, she faintly hears Trevor calling out to her, and looks up to the second floor where her three friends are looking out from the window. Trevor tries hard to gesture towards the ground, and Y soon realizes that he is pointing at the two electronic devices which are still sitting in the glass boxes Tierno opened earlier. She remembers that they are called the Pokedexes, and quickly picks one up to activate it. To her surprise, it displays the names of Froakie and Chespin, and most important of all, the characteristics of their species, essentially working like a hand-held encyclopedia.

Mable states that they have theoretically accomplished their mission, since they were told to capture a Pokemon that is capable of Mega evolving and they have successfully snatched the child of Kangaskhan. Aliana agrees, and asks if they should retreat. However, Mable wants to seek revenge for what the kids did to them in Vaniville, and Aliana, making fun of Mable's stubbornness, laughs that it will be a good idea to teach them not to defy them again. With that, Mable orders a Flamethrower from Houndoom, which burns at Chespin, and Aliana gets Diggersby to use Mud Shot, which hits Froakie square-faced.

Y feels alarmed as Chespin is of grass type that is weak to fire and Froakie is a water type which doesn't resist ground. She quickly tells Froakie to turn its focus on Houndoom, but before she could give orders to Chespin, it is being gestured forward by X, who has suddenly bolted up from his slumped position and is charging towards the enemy, much to Y's shock.

Diggersby rams its left ear down in an attempt to crush Chespin, but the grass Pokemon manages to evade, and the blow creates a big hole on the ground instead. Y gasps that Diggersby's ears are just like fists, and watches in anxiety as the giant rabbit chases after Chespin by ramming its left ear down repeatedly while keeping Li'l Kanga captive with its right one. It soon corners Chespin with a punch that seems impossible to dodge, and the Vaniville kids cry out in horror, all except X, who stays calm, and tells Chespin to spin around. As it does so, it hardens the quills on its head, which instantly turns into spikes, piercing into Diggersby's ear as it makes contact. The excruciating pain causes Diggersby to cry out and flail, which loosens its hold on Li'l Kanga and makes the baby Kangaskhan fly off from its grip.

X hurriedly lunges forward to catch Li'l Kanga, and Y reads from her Pokedex that the wood cover on Chespin's head and back is so thick that even a direct hit from a truck wouldn't faze it. She wonders how X knew of this ability of Chespin, and the boy simply shows her the other Pokedex which he has picked up. Y feels somewhat annoyed that X has beaten her to utilizing the device first, and lets out a grunt.

Mable is furious about losing the baby Kangaskhan, but Aliana giggles that there is no need to get angry. She tells Diggersby to deliver its best and most powerful punch, and finishes her line with a warning that Diggersby will receive a horrible and painful torture if it disappoints her. Diggersby cringes at the sugar coated threat, and braces itself as it charges towards Chespin with both of its ears curled up as fists. Chespin starts scaling the Dancing Ponyta Inn's external wall, and Diggersby quickly gives chase. Taking its chance, Diggersby delivers a powerful punch, but Chespin manages to jump out of the way and the blow ends up blasting through a hole in the wall. Chespin backflips to headbutt the big rabbit with the hardened quills on its head, and the powerful impact causes its opponent to faint. X then orders a Pin Missile, which Chespin fires towards Mable and Aliana, and pins the two Team Flare Scientists against a tree.

While Mable and Aliana scream in fury, X tells Y that they should probably leave. Y states that Trevor, Tierno and Shauna are still trapped upstairs, but at that moment, Trevor hollers that they shall be fine. Y looks up to see that the hole made by Diggersby's punch has created an opening on the second floor, and wonders if this is what X planned to do all along. However, the boy gives no reply and begins to return to his secluded mode.

Shauna yells at Trevor that they are not really fine since they don't have a way to get down, but Y suddenly gets an idea, and tells the three to jump out of the opening. Shauna thinks Y must be out of her mind, but Tierno decides to trust Y, and grabs both Shauna and Trevor under his arms before taking the leap. Just as it looks as if they are going to crash to their death, Froakie foams up the bubble around its collar again and creates a large cushion, catching the three and halting their fall. The kids then quickly climb back onto their feet, and start to move away, with X back inside his tent on Rhyhorn's back. Fletchy catches up with Y after having beaten the old lady and her Spritzee, and Y turns back to steal one last glance at the red-suited people. She has absolutely no idea why they are after X's Mega Ring, but is determined not to let them succeed and vows to trump their evil schemes.

A while later, the group settle down in a forest area and set up a fire place to rest temporarily. Shauna still feels shaken by what happened, and wonders how far they should run. Y replies that she has no idea, and feels unnerved by the uncertainty. Tierno says they should at least be thankful that Li'l Kanga didn't get taken away, and is also glad that X worked so in sync with Chespin. He suggests X add Chespin to his team since they seem to be acquainted already, but X doubts that it is a good idea. He states that any Pokemon that joins his team will suffer, and believes it is better if Chespin has nothing to do with him. Shauna doesn't know if she should call X considerate or mean, and gently lets out a sigh.

For Trevor, although so much has happened that night, the one thing that really caught his attention was the moment when something in Kanga's pouch glowed along with X's bracelet. To confirm his query, he seeks Kanga's permission to search its pouch, and to his surprise finds a small circular yellow stone with a light purple swirl pattern in its center. Clearly, the stone bears much resemblance to the one embedded in X's bracelet, and Trevor couldn't help but wonder if some strange interaction between the two stones when held by a trainer and Pokemon individually caused the transformation, a phenomenon apparently termed 'Mega Evolution' according to the red-suited people. Trevor has no idea what exactly connected the two stones, but starts to think it is some kind of bond that could not be explained by words or seen by the eye. Trevor's inquisitive mind makes him fascinated about this mysterious phenomenon, and he begins to ponder on what limit means, and what it means to surpass the limit.

While Trevor scribbles down his thoughts into his notebook, Y teases him and wonders what kind of new understanding he has gained. Trevor sheepishly states that there isn't any at the moment, and Y announces that she has one on the other hand. Her remark instantly draws the attention of her friends, and they quickly ask what it is. With a firm tone, Y says if what happened at the inn taught her anything, it would be the fact no hotel is safe for them to stay in from this point forward.

Meanwhile, Prof. Sycamore, in the company of his Bulbasaur, Charmander and Squirtle and a friend, is watching the Holo Caster clip which Trevor sent him. In the video, Xerneas and Yveltal clashed intensely, and their powers instantly wrecked the buildings around them. Trevor cried that it was not a movie that he was recording, but the clip is cut short before he could say anything else.

Sycamore wears a look of worry as the screen goes blank, and explains to his friend that the scene was captured by a boy on the day the Vaniville incident occurred. He expresses his astonishment that the Pokemon spoken in myths actually appeared, and thinks the footage is extremely valuable in assisting the investigations. He praises his friend for having invented the Holo Caster among many other things, since the recording would not have existed otherwise, and reveres him as a truly dignified man. His friend, a man with fiery red hair named Lysandre, doesn't take credit for the compliment however, and simply ponders on what he saw in the clip while sitting calmly on the sofa next to his Gyarados…
