Ep. 18: Lynn and Sarah renew their promise while a missing horse and lost necklace cause confusion.

Lynn arrives at school early but finds Louie there first. Mathilda and Phyllis reprimand her for bringing animals. Mathilda later forgets her necklace at the race track, where Jim returns it to her. Upon returning home, Lynn meets Sarah, who reminds her of their promise to become Ladies under a strong tree. They renew this vow, leading Lynn to realize Sarah’s feelings for Arthur. Paul informs Lynn that her horse is missing. She bikes to the stables and discovers only Gloria’s blanket. Meanwhile, Sarah and Henry follow Louie to Andrews and return him to the school stables. Andrews recalls that Mathilda removed her blanket and dropped her necklace in his stall. Cathy spots the necklace, and Mathilda claims she lost it that morning. Sarah leaves the scene.
