First I was 50 percent sure that sia will be killed but now I guess I am damn sure that sia will be stab. Precap indicates it.
I guess now since V knows that Sia loves raghav. he will take knife and would try to kill raghav but during that time. Sia would come and she would come infront of R and will get stab.
Or maybe now since V knows that Sia loves raghav. he might wait for sia to come home and then will stab her since he cannot see sia going to raghav. So he will take life of sia.
Either of these will happen I guess but this is confirm that sia will get stab.
