They might show that they planned his death after knowing about his cancer so that Kasthuri will marry Robbie.
They might add up saying that Kasthuri developed hatred for Robbie- So to bring them together Raunak planned with Kasthuri's mom all this( Remember her tyaking saris from Banaras to Malaysia- at that time we found it funny- It could be her moms plan) He planned it so that Kasthuri will be by Robbie and things shall happen as they are happening. Anitha might be a catalyst to evoke feelings in Robbie about Kasthuri.
So once again soft corner for Raunak will be developed by Kasthuri etc..
OMG I hope nothing above ehappens and let Raunak be a bad BOY....
What say....
