On another note, I think that the arrival of Roshni will have a profound and positive impact on Jai and Bani! For one, it will make Bani realize that she has fallen in love with Jai and that she doesn't want to lose him...and Jai in turn protecting Bani from his past proves that he is extremely insecure about Bani getting to know any shady dealings of his past as he doesn't want to loser her...
Else, why would Roshni's arrival rattle Jai to such an extent, when his whole family knows about her, with the exception of Bani...that means, Jai doesn't want Bani to know about Roshni and form any negative impression about him!
Okee, don't kill me for this, but I kind of like Roshni, one because Rakshanda is playing the character whom I like a lot and secondly Roshni seems to hate Jigyasa which can only be a good thing....and thirdly, if Roshni is really in love with Jai, then she won't overlook his happiness, which certainy doesn't lie with her!
