Could it be Kabir's plan? The proposal?

Think about it? Kabir's been doubting Radha's parents ever since his entry, he knows there's something they are trying to hide. He also mentioned about the accidental marriage prank and how he plans to turn that in to a movie. It could be that he already knows that they are none other than Radha and LD. May be he might try to help Radha clear her name in this whole Chaturvedi scam thingy and help LD see the true side of things.

By the way, why aren't they revealing who LD was talking with in that apartment?! 😛 Just reveal it already, will ya!😆

Yeah I also feel it's Kabir's plan to find out what Radha is doing in Mathura. Since Kabir said to have a golden heart, he'll most probably help LD and Radha unite once he finds out. As for the girl LD talks to, hmm let's see who it ends up being...I don't think it's a love interest but simply someone who he goes to to talk his feelings out because obviously there's no one in the Chaturvedi house who would hear him out.
