Christopher watches a science program about underwater life, which he enjoys because it proves that "all the facts you take for granted can be completely wrong." His father comes home and finds the mystery story Christopher has been writing on the table. He reads it and angrily confronts Christopher. Christopher tries to convince him he hasn't broken any of his promises, but his father raises his voice and grabs Christopher's arm. Christopher lashes out, repeatedly hitting his father: "I had no memories for a short while." It's unclear whether Christopher loses consciousness, but when he comes to, his father is breathing heavily, Christopher's hand is covered in blood, and he has a headache.
Christopher describes why he particularly hates the colors brown and yellow. He knows hating certain colors is "silly" but he hates them anyway. He compares it to being a restaurant and seeing food options you know you would never choose.
Christopher's father apologizes for hitting him and takes him to the zoo as a "proper apology." Christopher lists his favorite animals and draws a map of where to find them in the zoo. Over lunch Christopher's father apologizes again and they "hug" by touching fingertips.
This section ramps up suspense as Christopher's father uncharacteristically loses his temper and hits his son. Christopher previously suggested his parents often fought from the stress of raising a child with "behavioral issues" but this is the first outburst the reader has witnessed. Readers can connect the dots to assume if Christopher's father reacted violently enough to knock Christopher unconscious during their fight, there's a possibility he can be physically violent in other situations as well.
Because Christopher is incapable of directly expressing his emotions, such as how he feels after the fight with his father, the tangents offer clues. In Chapter 131 Christopher lists the reasons yellow and brown are his least favorite colors, connecting each with feelings of disgust. The placement of this tangent offers emotional insight without Christopher having to state explicitly how he feels.
