Delilah showed up as a judge in "Performing with Fiery Charm!" and served as a "Showcase Expert" for the Dendemille Town Rookie Class Pokémon Showcase, working alongside Gena and Santo.
During the Theme Performance round, she used her Furfrou to taste-test the Poké Puffs that the performers had made. Based on those evaluations, she helped move Miette, Jessilia, and Serena through to the Freestyle Performance. When it came time to crown a winner after the second round, she cast her vote—along with the audience—and ended up voting for Jessie.
