At some points, Frazier and Burris have pleasant talks in private, with Frazier revealing that other communities loosely associated with Walden Two have now cropped up, the most recent being Walden Six. Although enticed by Walden Two's obvious success as a peaceful community, Burris finds it difficult to look past Frazier's irritating pride and boastfulness about the community. During one conversation, Frazier admits to being boastful, but argues that his personality should not influence Burris's opinion of Walden Two and his own observations. By the end of their stay, the remaining visitors leave the community in a mostly impressed state of wonder, except for Castle, who has stubbornly settled on the idea that, somehow, Frazier is a scoundrel and the community is fraudulent.
