In Ray Bradbury's Fahrenheit 451, Guy Montag's curious teenage neighbor is Clarisse McClellan.
Clarisse is seventeen and stands apart from the conformist society around her. She notices ordinary details, enjoys walking, asks questions, and talks with Montag about ideas that his culture has taught people to avoid. Their early conversations help Montag recognize his dissatisfaction with his work as a fireman who burns books.
Clarisse is not Montag's wife; Mildred Montag occupies that role and is deeply absorbed in interactive television. Clarisse's presence also contrasts with the state's preferred model of fast entertainment and emotional numbness. Although she appears early and disappears from the story, her influence is crucial: she acts as the initial catalyst for Montag's curiosity and eventual rebellion.
