Alternate Character Interpretation: Did Arek kill himself? His and Therem's story, in light of the background mythos and history of Gethen presented in the novel, would suggest he did, and that it was his suicide rather than his kemmering with Therem that resulted in Therem's exile.
Genius Bonus: The novel is purely enjoyable on its own terms, but reading below the surface is required to uncover all the details, and a working knowledge of Taoism will certainly enhance it.
Tear Jerker: When Genly manages to make telepathic contact with Therem and he cries out his brother's name, having heard Genly's speech through his lost brother/husband's voice.
