It's the weekend, and Si says he's ready to go to the tutoring class. Si asks why he was treated so badly the day before. He's not angry, but he does want to know why. Si tries to get Si to tell him what happened, but Si can't tell him the whole story. Si says that he just hasn't seen Si for a few days, and that he is so brave that he wants to get close to Si. Si doesn't want to be jealous, and he tells Si to go ahead and start the class so they can get to know each other better. Si tells Si that he needs to teach him some formulas, because Si is a bit heavy. Si is worried that Si is going to ask him about the formulas, and then he'll have trouble telling Si what to say. Si thanks Si for the tutoring and the lunch, and goes home.
