I think thats the question everyone is waitin anxiously for. So lets have our predictions here.
Scenerio 1
I say Robbie will be super pissed at Ronak & Kasturi and will want to know the truth. So he'll call her up and demand an answer. She'll be too shocked and would not know what to say so Robbie will believe the form and Nikhil. He'll then not go with the shagun at her home.
Alka will get the perfect chance to humiliate Kasturi. Saying that she lied that Robbie will be comming with the shagun and that Robbie is not really serious about her and so the whole family will be against Kasturi (save the siblings).
Senerio 2
Otherwise, Robbie will show up at the house and will create a big scene which he like to do since he doesn't think before he acts. And Kasturi will feel comepletely humiliated and will scream at him and might even slap him and say that 'its over' since he don't trust her. Then Alka will again make fun of Kasturi.
Senerio 3
Robbie will make a scene privately or in front of chawla family and at the nick of time...Ronak the Rakshak or Divya the dumbo will come and reveal the truth and Kasturi will be saved yet again. Altho i donno what she'll do to Robbie for suspecting her again and what Robbie will do to her for hiding such a huge thing from him.
Please chip in and write your own predictions.
