Oreki’s history class is momentarily disrupted from an argument coming from an adjacent class; he recognizes Chitanda’s voice. After school in the clubroom, Chitanda tells the others what happened, and presents Oreki with the mystery of why her teacher made a mistake. After eliminating a few possibilities, Oreki concludes the math teacher mistook the lowercase a for a d in his notes, thus messing up Class A’s progress with Class D’s.
Oreki Houtarou is well aware he cannot refuse Chitanda Eru’s request to solve her mysteries, be they grand like last week’s, or relatively mundane, like this week’s. But while this mystery wasn’t as glamorous (it was just a case of Chi’s teacher mixing up two letters), the club took it just as seriously, and the episode didn’t skimp on the neat little details. For instance, the first half is merely the club discussing the seven deadly sins, including anger, which Chi believes necessary but chooses to avoid it whenever possible. She tries to stop an angry Ibara’s Fukube-aimed tirade with cookies. Once that box of cookies is open and we see that they’re letters, the solution is right there before us long before Oreki figures it out. This speaks to Oreki’s belief in luck as a major player in whether and how he’s able to solve things.
After the opening credits, the entire episode takes place in the clubroom, and nobody leaves until the end. Yet we’re still taken to different places: Chitanda’s story of what caused her to yell at her teacher is visualized as a kind of noh theatre with traditional masks on non-traditional mannequins (the teacher himself is a crash dummy). When Oreki feels Chitanda’s catchphrase “I can’t stop thinking about it!” coming on, he imagines hundreds of tiny, intent Citandas climbing over him like cute leaches with amathyst gazes. Indeed, after he solves this, Oreki is still frustrated by the biggest mystery of all so far, at least for him: what exactly is going on inside Chitanda’s head and any given moment…and why he can never refuse her.
