In a sense it was highly illogical for Kabir to have not figured out by now that Radha and LD are married. Like he already knew about a prank marriage that happened and was apparently looking for the video too but being the famous Kabir Kapoor, he couldn't find that video? He also somehow knew that Radha was at LD's house when he was halfway to Delhi. This is why I feel that he has known all along that Radha is married to LD and hence, he has been playing all these mind games. He knows very well that the new clauses are meaningless since they're already married but this is a punishment for Radha because she constantly lied to him about her relationship with LD. Honestly, does Kabir not have other film or work commitments? He's always busy annoying Radha and meddling in her life.
The clauses will force Leera to admit their relationship to him and I think this is where Leera will unite. Dadaji also seems like he's getting better so the truth will be out pretty soon. Articles aren't always reliable so I guess we'll just have to wait and watch.
