Whatever Neha is teaching Soha, whatever is her behaviour towards Dev and Sonakshi is all because of Isshwari. Isshwari ne agar usko equal love dia hota to uske Man me itni hatred ni hoti. Because Isshwari always cared more about Dev, Neha is now very jealous of him and can't tolerate Dev has everything which is required to live a luxuries life. I am not saying Neha is right. Vo koi dudh piti bachi ni h ki usko samjh na ho ki jo uske sath hua vo uska past tha, usko Soha ke mind me gandgi ni bharni chahiye. Lekin is hatred ka reason hi uski double standard mother hai. Neha Was always jealous of Dev
