Sonakshi 's question was on spot...how could Dev question her parents relationship just because her dad didn't behave well with him...because if she wanted she could also questions relationships at his end because none of them behaved well to her...
Now Asha wants her daughter to enjoy her life so she concentrated on what needs to be done to correct her daughters messed up life...want Soha to have both parents with her living happily...she knows Sonakshi still has feels for Dev and the other way around too...She knows Sona might never accept anyone else in her life...but hers and Devs bitter past will never allow them to even talk amicably ...today she saw a sign of giving in from Dev...( I know you all are angry at Dev's behavior towards Bijoy ...but if you compare with Season 1 Dev...he would have literally thrown Bijoy out of his own house by now...) For Soha he controlled his anger asked sorry which is so much away from Dev's character...because for Dev his mom is never wrong so why apologise on behalf of her.??
And hence the question to her daughter how do you know your father is the best husband?? She took this opportunity to tell Sonakshi that a relationship works out because two ppl decides to make it successful...Asha emphasized that for both Bijoy and her their relationship was imp...and because of which both did adjustments and sacrifices to be where they are today!!
I hope Sonakshi ponders on what happened with her relationship with Dev and how it failed miserably...
I loved this seen so much...
PS: Now the question is why try to correct Sonakshi...why cant she do that to Dev...my answer would be one should try and correct our own kids first before we find flaws in others kids...
