A wild Polteageist secretly boards the Brave Olivine, leaving purple puddles that Liko and Roy investigate. Jealous of Shuckle’s berry juice, the Polteageist challenges it, leading to a private match that welcomes the newcomer. Liko and Roy observe this but choose not to interrupt. The next morning, Friede casually accepts the Polteageist, while Diana reveals she has known all along. She shows that the Polteageist transformed her teacup into a Sinistea, indicating the crew allowed Liko and Roy to uncover the mystery independently. This episode highlights the crew's secret knowledge and the Polteageist's integration into the ship's life without direct interference from the main characters.
