As our heroes continue to the Lumiose City Gym (without Clemont) for Ash's next Gym battle, Serena is doing some training for her next Pokémon Showcase. But trouble is brewing, and Fennekin and Pancham are fighting fiercely! Things are getting out of hand, and a frustrated and angry Serena leaves to take a walk and think things over-alone. In town, an unknown girl-also a Pokémon performer (the Kalos Queen Aria, disguised as Eliza), befriends an unhappy-looking Serena, urging her to smile! And to come along for some shopping and lunch... After Eliza suggests Serena apologize to her Pokémon, all is forgiven. But Eliza has followed Serena, and challenges her to a double battle to strengthen the bonds between Trainer and Pokémon. Serena is off to a shaky start, but remembering Eliza's advice to smile, things turn around quickly! Suddenly Eliza mysteriously has to go, leaving their battle unfinished. Later, watching Aria's performance on Pokevision, Serena is shocked to see Eliza was actually Aria in disguise. But Serena's confidence and optimism has been revitalized, and it's off again to Lumiose City!
