Lumiose City is nearly back to normal, and Serena has an idea for a celebration. With Professor Sycamore’s help, she and Shauna put on a special performance for everyone! They’re soon joined by their Master Class rival Jessilee, and the show is a huge success!

Serena wants to keep pursuing her performance goals, but she’s not sure about her next step. With the support of Ash and her mom, she finally decides to turn down Palermo’s offer so she can keep improving on her own. But Palermo has a surprising response: she suggests that Serena travel to the Hoenn region to try her hand at Pokémon Contests!

Following the rebuilding of Lumiose City and the reopening of Prism Tower, Serena is thinking about her future and remembers the offer that Palermo made to her as Bonnie draws their attention to the TV where a news report on the reopening of Prism Tower is showing and mention that there are still many wounds to be healed in Lumiose City but the light of Prism Tower is sure to guide everyone on the path to recovery as Bonnie says that lighting up the tower was great and everyone enjoyed it as Clemont calls it the first steps to recovery which gives Serena an idea. Outside Professor Sycamore's lab, Serena is speaking with Professor Sycamore who says her idea is a great idea and agrees to help as Serena thanks the Professor for his support.

The next day, Serena laeds Ash, Clemont and Bonnie towards the center of Lumiose City who have no idea what is going on.
