From Christopher's own words, we learn that he is a 15-year-old boy with a fascination for logic and facts.
He enjoys order and consistency, as evidenced by his preference for prime numbers and his aversion to yellow and brown (page 1). He also reveals a strong sense of justice and a desire for truth, as seen in his determination to solve the mystery of Wellington's death, even when faced with opposition (page 48).
Christopher's direct and literal way of sharing information reflects his unique perspective. He often explains things in great detail, even when it may seem unnecessary to others. For example, he meticulously describes the physical characteristics of Wellington (page 2) and the precise steps involved in solving a complex math problem (page 17). This suggests that Christopher processes information differently and may struggle with social cues and nuances.
