At the beginning of the episode, a collection of Ash's previous Badges and trophies are shown in his room. They include: The Pokémon League Badge from the Indigo Plateau Conference, the Winner's Trophy from the Orange League, his Badges from Hoenn, Sinnoh, Unova, and Kalos; His Symbols from the Kanto Battle Frontier; His Z-Power Ring, equipped with his Pikashunium Z; His Championship Trophy from the Manalo Conference; His Exhibition Match Trophy from his battle with Professor Kukui; A Poké Doll, a possible reference to Lillie's departure during the ending of Pokémon Sun and Moon. This makes the Johto arc the only leg of Ash's journey not represented in this display.

Professor Cerise offers Goh a Kanto starter Pokémon of his choice, but Goh declines the offer, wanting to make Mew his first Pokémon instead.
