yes Neil yelled at Avi but his concern was both their safety.
Usually Avni is far more careful than this attitude of make Juhi happy bandwagon.
She slipped in her caution because she is feeling guilty that Mishti does not want to be with her mother because she loves avni more.
So she is trying to soothe Juhi.
This is where she lost her alertness.
In normal circumstances she would not have done that.
Neil should have spoken to her alone and also called her while he was driving from work.
But Avni took the fight more when she first brought up the issue of Neil saying sorry when at that time both were at fault.
Even then neil was trying to make her understand.
But her NAKAABIL word went too far. She could have just left it that you were unable to keep him in custody, because that was a fact.
Even in fights both husband and wife have to be very careful on uttering words like this.
this is the same husband who she thinks is the most upright and dutybound police office. He is the one who brought her trust back in people and the law system of the country to a certain extent.
Just like he is proud of her standing together with him, she is proud about the kind of police officer he is.
However their love is stronger and they will not take it to heart.
