Following truths were never revealed to Kartik ever....
During JKG....KD manipulated and forced Naira to change their (Kaira's) relationship according to societal norms...
After Shubham's death Suwarna deleted Kartik's call logs....he never knew Naira ever tried to contact him in those 2 years...Kartik never got to know how Suwarna didn't let them communicate...thereby prolonged separation...
Kartik will now never get to know how Vedika's suicidal drama was the reason behind their divorce and custody battle...
Right thing would be consulting lawyer to clarify marital status of Kartik & Vedika....in order to avoid bigamy claims they showed Kartik and Naira divorcing each other again....Vedika's marital status could also be clarified by Kartik consulting lawyer....than they could have shown Kaira confessing their feelings or taking initiative to talk to Vedika...I can't believe same woman whose suicide drama and selfishness was the reason behind Kaira's divorce will reunite them....why can't Kartik be shown talking to Vedika and clarifying everything...they are not legal husband and wife...as they got married before Kaira's divorce....he could have shown telling her...
"Vedika you are my friend but I never considered you my wife...u aren't also my legal wife...never thought u would do something like manipulating the situation in your favor... I'm hurt and shocked knowing how you manipulated Naira and got us divorce each other and fight for custody battle....didn't you have any conscience?....if you didn't try to separate us...we "might" have lived like a happy family...me my sherni and my tadpole...you had no remorse for separating us....but Naira...she never wanted to hurt you....she had conscience...she has been guilty...why weren't you guilty?....you got us divorced but she didn't want me to divorce you or to sign annulment papers....you didn't even think how I would stay without my son if Naira took him away....these are annulment papers....you are still my responsibility you can stay with our masi dadi in new york (anyone remember her character played by Aruna Iranai), she will take care of you....you can be a part of our company over there I will take care that you won't have any difficulty in adjusting there...you can live as you want to live.... I'm not your husband....you are free to marry....my fault was I married you despite of knowing I can never love u....your fault was you knew Naira is my legal wife still you wanted to be my wife....we were never meant to be...I'm sorry for hurting your feelings...but staying in loveless namesake void marriage will suffocate us both....I wish you didn't give us another emotional scar....emotional scar of divorce...emotional scar of betraying us when I trusted u like a good friend..."
