You sit in companionable silence for a few more moments. Mattsson offers you the water skin again, and after you take another drink, he finishes it and stands up. "I’ve got to go," he says, "but if you want to meet some people who can help you get settled in around here, I can take you with me."
Stand up and go with Mattsson. Decline. Once Mattsson has left, go talk to the people by the wagon.
