Ranveer kidnapped daljeet and then sent goons he hit daljeet many times not only this he blackmailed sahiba to forcefully marry him otherwise he would send daljeet far away or kill him when ranveer became rich according to jazz's contract he used his power and money for wrong purposes whereas daljeet did tit for tat because he always cared for sahiba don't you remember he sacrificed his love for sahiba by getting them married in the same gurudwara where he was about to marry sahiba,ranveer kept on forcing sahiba to leave daljeet and show everyone in the house that they are happy but daljeet never forced sahiba to love him
daljeet is taking revenge and daljeet has become prudent now he has become wise daljeet was the only person who kept on sacrificing his love and his life for sahiba's happiness
whereas ranveer always kept on forcing himself on sahiba
when sahiba was jumping from the cliff daljeet saved her when sahiba was caught by policemen for illegal visa daljeet saved her
daljeet would have said sahiba in the beginning when he was living with sahiba in london to love him because she married him or he would have said that sahiba please leave ranveer I love you
but did ever did that?he would have said in the gurudwara that sahiba forget ranveer throw him out of your life you are my wife and you meeting ranveer isn't good what will my parents and family will think,but did he said that even once?
did daljeet ever killed ranveer before?
all these things sending ranveer to mental asylum and dna and then ranveer becoming a labourer all this he did because ranveer kidnapped him and because he harmed daljeet
