Coming Back into the Cold! (Japanese: オーロラの絆！アマルスとアマルルガ！！ The Bond of the Aurora! Amaura and Aurorus!!) is the 23rd episode of Pokémon the Series: XY.
Ash, Serena, Clemont, and Bonnie meet up with Alexa again, who is covering the new fossil exhibit at the Ambrette Town Museum, meeting the revived fossil Pokémon Amaura and Aurorus in the museum's cold storage. However, Team Rocket arrives to steal Amaura, leaving Ash and his friends on a rescue mission.
Before going to Cyllage City, Ash trains his Fletchling and Froakie. Froakie uses Water Pulse on Fletchling and hits an illusion, due to Fletchling using Double Team. Froakie uses Bubble, hitting Fletchling. Ash compliments them both, as does Alexa, who appears. Alexa sees Serena has decided to travel with Ash, Clemont and Bonnie. Dedenne greets Helioptile, who startles him. Alexa has heard they met Viola, as well as Grant, at the Battle Chateau. Alexa admits she came here to do research on fossils. Clemont knows what she is speaking of, for in Ambrette Town lies the fossil lab, where scientists study fossils of Pokémon. Alexa has heard they made a discovery there, so invites the heroes to come there and see the discovery. Serena tells she does not know much about fossils, but Clemont replies he loves them.
They come to the lab, where they are greeted by Thaddeus and enter the lab. Team Rocket overhear them and release a spy camera to follow them. Ash and Clemont are fascinated by these fossils, but Serena is not amused. They continue following Thaddeus, who gives them winter jackets. They enter the complex and everyone is freezing from the low temperature. Ash trips over and is greeted by a Pokémon. Clemont sees it is an Amaura, a Pokémon said to have lived in colder parts of Kalos region. Soon, an Arurous appears as well. Thaddeus tells them they found their parts frozen in ice, but were revived. Arurous comes to Ash, wanting to play. Thaddeus tells since they didn't have much predators, Arurous and Amarua are very friendly. The heroes hug and pet Amaura, while Alexa interviews Thaddeus. Team Rocket see this through their spy camera, intending to catch both Amaura and Arurous.
Serena and Alexa are feeling cold. They decide to go out, else they will catch a cold. Team Rocket sees everyone going out, so they go to break in. Despite the cold temperature, they gain the attention of an Amaura and fool it, then capture it into their truck. James and Meowth try to fool Arurous, but it is too heavy. It notices Amaura captured and is upset. Two men come and see Team Rocket, who decides to grab Amaura and drives off. The heroes hear what happened, but Thaddeus is more worried Amaura will get weak, for it is weakened by high temperatures. Amaura sends a link to Arurous, who comes out and communicates back, through aurora lights. Arurous follows the aurora, as do the heroes and Alexa, while the scientists prepare transport once Amaura is found. Amaura releases cold air. Team Rocket feels cold, so Jessie turns the heat up. Amaura is feeling weaker, causing the aurora to vanish.
Team Rocket stops, for their tire has been pierced. The heroes stop at a river, since they don't know where to go. Arurous stands up on its hindlegs and yells out. Amaura hears Arurous and signalizes through aurora lights where it is. Since it is across the river, Arurous freezes the river to cross it. Amaura is weak, causing the lights to vanish, but the heroes managed to find the location, where Team Rocket lies. Clemont sends Chespin, while James sends Inkay. Chespin uses Pin Missile, hitting Inkay. Bonnie and Alexa sneak behind, but are stopped by Meowth. Serena sends Fennekin, who uses Hidden Power on Meowth, but is countered by his Fury Swipes. Arurous appears and freezes Meowth using Blizzard. While Alexa, Serena and Bonnie found Amaura, Pikachu uses Thunderbolt, but gets reflected by Wobbuffet's Mirror Coat. Arurous protects by using ice, then uses Blizzard on Team Rocket, freezing them. Pikachu uses Thunderbolt, blasting the frozen Team Rocket off.
Amaura is still too weak. Arurous lies near Amaura and releases cold air, cooling Amaura down. The scientists arrive with the truck to transport Amaura and Arurous back to the lab. Later, Thaddeus arrives with Amaura, who hugs everyone and plays with the heroes in the snow. Alexa is also pleased, having gathered info for her article.
