Three years ago, Goh met a boy named Horace on a family trip to Azalea Town in the Johto region. Horace was searching for the Mythical Pokémon Celebi and the two decided to search for it together, but Celebi was hard to find. The two of them promised to meet up again the next day to continue their search, but Horace never showed up. In the present, Goh returns to Azalea Town and ends up encountering the ghosts of his past. Ash and Pikachu are absent from this episode. (Source: Wikipedia)
