Despite the great power that his intelligence grants him, he admits later in the series that his superior mind is a kind of curse: he can't stop thinking, calculating probabilities, and formulating plans; so he never sleeps. In fact, he attends school because he believes social interaction will slow his descent into madness. Jeremy is the only human to know of Barry's abilities (other characters have discovered them at various points in the series, only to have Barry erase their memories). Like Barry, Jeremy is a profane and irreverent ten-year-old, although Jeremy shows a great deal less maturity and restraint. He has an enormous and somewhat curious interest in women, despite not having yet entered puberty. He tags along for all of Barry's adventures, usually to provide comic relief. He fervently denies any attraction to Roxie (despite evidence to the contrary). When asked by Roxie why he keeps Jeremy around, Barry replies that he enjoys having someone not in awe of his genius or asking questions to keep him a bit grounded. A classmate and friend to Barry and Jeremy, Sara (sometimes spelled "Sarah," most likely a typo) is probably the smartest character in the series next to Barry. She is confident, brave, and resourceful; qualities that have made her an able participant in some of Barry's more dangerous escapades. Barry is very attracted to her, and dealing with their relationship has been perhaps one of the few challenges he cannot surmount with his intelligence alone. It is not clear to what degree Sara reciprocates this affection, although she clearly likes and respects Barry. She has twice learned of his intelligence, but Barry erased her memory the first time and altered the past through time travel the second time in order to save her from death. Though Sara's death was averted, Barry was intensely - though privately - devastated by the experience. Whether or not Barry will eventually admit her into his confidence remains to be seen. Roxie is a Bigfoot whom Barry and Jeremy met when Barry's parents were kidnapped and nearly eaten by another Sasquatch. Far more intelligent and ambitious than the lazy majority of her kind, she was able to secure Barry's help in removing most of her hair so that she could pass for human. Despite looking like an eleven-year-old girl, Roxie is extremely strong, fast and agile, and often forgets that she must pretend to be weaker to maintain her cover. She is a voracious reader, and prior to meeting Barry used to break into libraries in order to gain access to books.
