Barnabas is K.'s one live wire to the Castle, delivering messages that may or may not come from Klamm, and he believes in his errand with a sincerity that makes his lack of an official suit painful to watch. His family's disgrace hangs over him, and his sister Olga speaks of his service with a mixture of loyalty and doubt. He matters because he is the book's clearest picture of what it costs to serve an authority that will not confirm you exist.
