Yes, though the mystery surrounding Dev is solved, i do think that there is one more to follow, with regard to Shelly's father... They have not shown his face till now. They have shown him to be a psychic case, with Shelly giving him regular consultations with the doc... He always keep instigating Shelly...
Now in yesterday's episode, they showed Shelly telling her father that his identity might come to the knowledge of Adi one day... To this, his father said that he had been working there, long time back, Aditya might not even remember his name... Its been quite a long time now...
So this means that Shelly's father used to work for Aditya or probably Aditya's father .... Now, i think there is a story with a link to Balraaj family for Shelly's father losing job and maybe going mad.... So i think this is the new twist that can be expected...
