First off when Mahi asked Shabd about his childhood he just tried to change the subject..
Secondly, the whole issue with Kamya
I also feel that Shabd personally has a past. Not just Suhani but I feel he also has some secret
The whole Kamya deal..My prediction is that Kamya was suppose to get married to that guy Rajveer(that's the name on the wedding card) and I think Rajveer was in a car accident or he left her and Kamya still never got over that. That's why she always wants her "shaadi ka johra" since she still cant accept the fact.
