Shakuni insists that still they have their wife Draupadi left for the game. After some initial reactions; she is put in the game and Yudhisthir looses again.
Duryodhana orders his men to bring Draupadi in the courtyard. She refuses. Hence, Dushashana; one of the brother of Duryodhana is sent to bring her; and is ordered to drag her into the palace. Dushashana follows the commands and Draupadi is in the courtyard. She is insulted by Duryodhana as he wants to make her sit on his lap. This is challenged by Bhima who woes that he will break his thigh and kill him eventually.
