I think Pahua and vhameli will provide some comic relief as well as help kaju trap the Villains...
Yeah, when Raju will go to Mumbai, they will all go to mumbai as well! and as sharmii said, they will just be comic relief. They just loosen up the tension for the audience. It is established that Chameli is no threat to DK. which is a good thing or all of us bhoothnis would have strangled chameli š
