Daisuke is a good boy. Shuji makes a mental note to give him treats later.

This time, Shuji doesn't touch the book. (He can check Spark Notes if he has to.) Instead he goes through Togusa's personal notes again. Does he have anything written down on his own memories that might provide some context?

Belatedly, it occurs to Shuji that this might be a bit invasive. But Togusa gave him permission, so he probably won't get mad about it...
