And Arun actually talking nicely to Dhristi came as a shock to me.... hope they keep building up his character like this and do give us a better explanation re: his toxic treatment of his daughter for all these yrs.
Drishti also could have died in the terrorist attack, so maybe the thought of losing both kids is behind the change, just like it's why Shael is starting to care for someone other than himself and his witch of a wife.
