Well since yesterdays (india) episode it has become relatively safe to assume that Jai killed someone in a hospital room on 29th june 7 years ago!! The question is how is it connected to Bani and how is she going to take it??
Obviously she is head over heels in love with her husband but is that enough to see them through what is going to be a pretty rough patch? Bani is by no means a weak character - if she was she'd have left Jai months ago - after everything he's said and done to her in anger she'd have slapped him and walked out.
My guess is that we're going to see a total role reversal!! Before we had Jai forcibly tied to Bani causing him lots of pain and anger which she bore the brunt of (out of guilt, pity, whatever...) after the park Rd raaz (finally!!) is out in the open we will probably see Bani feeling forcibly tied to Jai. She will probably want to leave him - most likely from feeling betrayed personally rather than any moral reason.
She probabaly won't be able to leave the house though as Mausi, Dadi, Adi etc won't know the Park Rd raaz (i'm guessing only the audience and Bani will find out) - but she will be the one who doesn't want anything to do with Jai this time. He'll be crying for her forgiveness and bearing the pain and solitude etc and we'll be back to square one desperate for cute scenes promising better times and future happiness.
I dont know how they're going to deal with the Rano-Saahil issue and i dont really care (no offence!) There's also the possibility that Bani really does become pregnant which is what stops her from leaving Jai..... i dont know i'm just rambling!!! Sorry for going on and on so uninterestingly, i guess we'll just have to wait and see what Ekta has in store next week!!!!!!!!
