Dr. Banerjee is a cheerful doctor living in the town of Shahkot. He enjoys giving advice and he tends to the wounds of several characters, including the spy and the Hungry Hop boy. He also briefly visits Sampath to give him a checkup shortly after Sampath moves up into a tree. Dr. Banerjee concludes that there’s nothing wrong with Sampath physically, but that he (Sampath) must simply be insane.
