I think Ishwari never thought Dev would need anybody else other than her as she is. She wanted to be the perfect mother as Sam mentioned. Society, maamaji and Dev fueled her illusion by putting her on the pedestal and calling her god. She has got used to being Dev's god so much that she does not want him to act as himself. People are supposed to act as per god's will right? 😉 And god never makes mistakes. what ever god does is for that persons own good, right.
I think the reason Ishwari still blames Sonakshi and her family is because they did not conform to her idea of how the wife, DIL and brides family should be. They showed the loopholes of her upbringing. She still thinks all the decisions that she took on behalf of Dev were correct, because she has not really seen any negative consequences( from her perspective). I mean she took the decision of prenup -- she saved Dev's business and money from a gold digger, she made Dev give Vickky a higher post in his company -- Vickky took care of the office these last 7 yrs when her son was not doing his job etc... The truth about the extent of Vickky and maami's villainy is the only thing that can help Ishwari understand the consequences of her actions and decisions.
Coming to today's episode I loved the subtle hints that they showed especially in regards to Dev - Sonia's relationship.
1) In the conversation with Sonakshi in front of his house, Dev asks her if she was there to meet her "old family" or his mother -- if Dev and Sonakshi are divorced how is his family still related to her. I don't think they are legally divorced. Just my POV
2) When Dev gets to know about possibility of earthquake, he calls the CA and asks him if there were any employees still working in "hamare office". Wasn't he the one who was shouting till even yesterday's episode that it was HIS company. But the when the CA repeats the same words he realizes what he actually said. It was vey telling.
3) the last dialogue of the episode -- only I can hurt you. It reminded me of his dialogue during the fight regarding Ritwick's loan cancellation and building. That time Dev had said "tum pe, tumhare aasoan pe, tumhare har cheez pe haq tha aur rahega". In shimla he said "feel pain when you are hurt". All of these are where he is saying that anything negative in her life she feels are his. He is happy when she is happy, but feels her pain... Did he really leave Sonakshi to fend for herself when she was evacuated from her home in the middle of the night. I seriously doubt it. I strongly feel that Dev kept track of her in his own way. Maybe more professionally than personally.
4) Both the time they showed the tremors, they showed Sonakshi as shaken, but Dev standing firm. Maybe CVs are hinting that in upcoming episodes Dev will be the stronger one in their relationship and Sonakshi will be the vulnerable one.
Looking forward to how the story unfolds. It is becoming really interesting... 😃
P.S: I wanted to say this to Vickky and maami today -- your time starts now. Like how they say at the beginning of an exam or a quiz (like game shows)... 😃
