I really didn't understand how he could say to Golu that Sonakshi didn't fulfill her promises to him... something in the lines of sath janam ka sath. All the promises were broken from her end according to him. Unbelievable!! I really don't know how the CV's would redeem his character.
I think the only replacement to his ego and anger towards her would be guilt, when he comes to know of her struggles and pain to make a living for her family and how when their daughter was born the only way they could celebrate was to distribute sugar, like he did when Nikki was born. How ironical would that be!!
Sonakshi has been shown to be strong from the very beginning which I applaud. In fact one of my favorite scenes from the serial is when she tells Dev that in her fairy tale he is her Prince Charming but in her battle with the dragon she just wants his support as she is quite competent enough to fight her own battles. However her Prince Charming was never there to support her and she had to fight her battles on her own. No matter how strong a girl or let's rephrase that ... no matter how strong a person is, he/she always has a breaking point and hope this time around if Sonakshi reaches her breaking point Dev is there to lend her a hand.
