Angie the answer again is Dev/Abhays mule like attitude...MR does not have to do anything. Remember few weeks back he had told Radhika that a womans honour is like glass or something like that.........even one bad name can destroy it easily.........when he said that I thought about Kannika and Abhay.........to the entire society he has been living like a husband with Kannika for five years and this Abhay might think that he will be destrying Kannikas honour so thats the reason why he might continue being stubborn......and if this is shown then Rad should definitely leave on her own and give him the space.
The PF hasn't got their waaris because from MR's disclosure they know that if Abhay is Dev, then Deepu is not his child as he was conceived before the accident. The only reason for everyone to agree to MR's demands would be to save RP title for Dev.
