Who is Bose from The Inheritance of Loss and what is their importance?

Bose was the only friend the judge made while studying in Cambridge. He may have been the only friend the judge ever had in his adult life. He was a different type of person than the judge, more outgoing and optimistic. He breaks the judge's heart when he tries to uncover the truth about their lives—how they are never accepted by the white Westerners, no matter how hard they tried. He is more in tune with reality than the judge ever was.
