Oliver Bates, ten, was a shy kid. He had a round face, brown hair, and radiant blue eyes that Sally could get lost in for hours. He often regarded people with scepticism and mistrust, pondering their intentions for interacting with him while asking mordant questions. Being the new kid on Sally's street and at her school, Olive was ostracised by the other students, making it hard for him to adjust to life in a new place. Truthfully, he preferred spending most of his time alone, though he did enjoy socializing with Sally on occasion. Oliver was raised by his mother as a single parent and never met his estranged father, though he never let that bother him—he barely remembered his father to begin with. His speech had a noticeable stutter to it that could annoy some, but for Sally, it was his cutest trait.

Sally Witherspoon, a ten-year-old girl, practiced stoicism by refusing to let anything affect her mood. She had long golden hair, blue eyes, and a small face which could barely done the black spectacles she needed to see. Sally was raised by her parents as an only child; they adored her eccentricities despite their inability to comprehend them. As a stoic little girl, she lacked friends; her uniqueness creeped other children out. Even amongst girls Sally stood out, since she was uninterested in most girly activities and hobbies. Her voice was emotionless and monotone—paired with her permanent neutral expression.
