Another scene shows that Baankey's sister is about to have sex with Gyanesh in a hotel room but he refuses in a comical way.

In a scene,it is revealed in a conversation that Baankey's sister has made out with many boys

Chutiya (fucker) said once

The word "Chutiya" is used in the conversation happening between Gyanesh and Baankey at the end. Its not beeped while playing on Amazon prime video. If you are watching with family be careful while playing that scene.
