Brian Michael Hackett (played by Steven Weber), Joe's younger brother, arrived after being asked to return to Nantucket by Joe because of something left to the brothers in their father's will. The two had not seen each other in six years, after Brian ran away with Carol, Joe's fiancee. Apparently, however, Carol and Brian are no longer together because she left him for someone else. Anyway, Joe and Brian settle their differences and Brian decides to stay on Nantucket to work for Joe at Sandpiper Air.

Brian Hackett is a humorous, often sarcastic person. Two years younger than his brother Joe, he did not feel the loss of his mother to the same extent. People often consider him not serious enough about anything, but laughing and joking are the ways he deals with serious issues. His two most serious relationships have both failed, one with his ex-wife Carol, the other with Alex Lambert.
