Hi
The story I feel is going again in loop. I think at present Dev is more scared about Sona leaving him and will do everything to not let that happen. Anger and love r two phases of the same emotion, so he is angry at Sona for not understanding him. So he will do everything to bring her back , he would most definitely buy the house ,could get Boses in street. At present consumed by anger and scared he will not see right and wrong.
Separation will b there but long. Unlike last time he just has to bring her back as she is already his wife. Sonakshi has already superseded Ishwari in Dev life, this tract will cause that realisation to both Ishwari and Dev.
So we will b treated to constant fight and pinning and yearning from both Dev and Sona.
This is Dev, flawed, vulnerable whom he previously said Sona dosenot get to choose to b with him or leave him. He will b there she just had to deal with it. Sona will b forced to comeback , but this time Dev will b more receptive then can hope for redemption.
Just expressing my view after analysis epi clinically. Not my personal opinion about the character. Cause nobody will b so hopelessly romantic to tolerate a guy like Dev .
