When the police show up the next day, they decide Pierre Anthon must have set fire to the sawmill because he couldn't deal with the meaning, and nobody corrects them. We never learn what really caused the fire.
The kids go to Pierre Anthon's funeral, and some of them even cry, because it's beautiful. But more than that, they're crying because of what they lost and gained. They know they gained something; they're just not sure what yet.
After the funeral, everybody goes to the sawmill. Sofie brings containers from home and everyone saves some ashes.
They can almost hear Pierre Anthon's voice in their heads, telling them death has no meaning because life has no meaning.
