When i noticed that specific memory of when he "messed up" being probably related to a farm animal box, then the secret became even scarier. Specially when the most recent chapters show us a wooden box with a chicken in his childhood memories and idk idkkkkk it os suspicious. The accident and the chicken might be related

So when he first remembers the box he thinks of it as a cardboard box, but when he looks at inside it, the box suddenly is a wooden box. Like, the kind that hold either fruits or small animals like chickens. I dont know what it means but i wanted to point it out that his memory is faulty
