you r forgetting one thing;
bani wanted him to hate her and she did a fair job of convincing him.He did want to know the truth but bani didnt want to tell him.He s gulty of not confessing to her,that's all
i am not supporting anyone here .i am just putting things in perspective.
frankly my dear now i don't give a damn. The serial leaves me cold.
but again u r also forgetting one thing varun that JW was quite sure that there is some reason behind whatever bani was doing and even when massi fell ill she told him that whatever bani is doing is for benefit of JW then why he didn't believe massi and went to dubai with pia. why on earth only pia was the only person he took along, don't he had any other capable person to go and what was the point of taking pia when she working independently for his some other office. so i think jai was still attached to pia unconsciously and ONS was result of that.
anyways every one has his/her own beliefs and sorry if any of my comments u find offending.
