The characters do two things in the dialogue:
- Stating: Silas and Bod state how they feel—disappointed and sorry.
- Explaining: Silas explains why he feels the way he does, which you might notice he does by describing triggers.
What's Silas' emotional loop?
- Trigger: Bod sneaks out and then Silas finds him smelling like trouble.
- Emotion: Disappointment.
- Behaviour: Tells Bod he's disappointed and shakes his head.
What's Bod's emotional loop?
- Trigger: Silas says he's disappointed.
- Emotion: Sorry.
- Behaviour: Acknowledges Silas' feelings and apologises. Stands there in the rain.
Notice the rain on Bod's face?
Gaiman reinforces Bod's sadness by adding the detail of the rain on his face—another example of reflecting emotion through a description of the world.
