I know many of your are hoping that Bani is pregnant, since we all saw her throwing up on the beach. Trust me, I hope Bani is pregnant as well, cuz this is the only chance left that will bond Jai and Bani forever....and maybe, in time, they will find their way back to each other (especially if the ONS didn't really happen, and the father of Pia's baby is actually Pushkar; thats if she's even really pregnant)....
When it comes to Bani throwing up however, it could also just be a normal reaction after she realized that her husband slept with her own sister....if any of you watched Kahin Tho Hoga, when Rajeev was on it, you'll remember that he had the exact same reaction when he found out that Kashish and Piyush had slept together.....I think if it was any other woman, Bani would probably not have felt so sick to her stomach, but because in this case the other woman was her own sister, this kind of a reaction is very realistic.....
Bani also figured out that Pia got pregnant while she was in Dubai, so it probably disgusted her thinking that her husband slept with both of them during that same time....anyways, to say the least, Pranchi did a FANTASTIC job and portrayed that scene with full conviction..... she is truly becoming an admirable actor!!!!
