Episode summary
Our heroes have made it through the Ultra Wormhole, but when they find the captured Lusamine, they’re shocked to find she wants nothing to do with them! With an Ultra Beast controlling her mind, it’s up to Lillie, Ash, and friends to rescue her. Their Pokémon spring into action—but so do Lusamine’s Pokémon, who are also under the Ultra Beast’s control. Lillie gathers her courage and reaches out to Clefable, recounting the fun they had together in years past. Her reassuring persistence pays off, and Clefable breaks free of the Ultra Beast’s control. Meanwhile, riding on Solgaleo’s back, Ash presses on to find Lusamine—and the Ultra Beast.
