PV of Raj and Sarita:
1)Before it reaches the marriage stage for Viki and Sarita, Raj realizes his folly and pleads Sarita to reconsider. (Highly improbable)
2)During the mandap pheras Sarita falls unconscious and we get to know that she is preggers thx to the bhaang episode so marriage is called off
a)Sarita might think that the timing sucks and Raj will now only be with her for the sake of the baby
b)Raj might be happy as fate played a role to stop the marriage and he gets another shot with Sarita but does not show how glad he is so Sarita's misunderstanding continues.
Pt 2 is very filmy but soap hai is liye anything can happen.
3)Viki is actually about to die and wants to set up his son with a family before he dies. He knows that Abhi wants Sarita but he has to get Sarit and Raj the package so this is some very twisted way to make Raj and Sarita close.
This is my out of the box track but it can also happen.
4)Divya can also be killed off leaving Raj all alone and Sarita refuses to let him mourn all alone there by rejecting any offers of PV.
OK now these are the scenarios for SaRa PV to happen.
Do add any other possible scenarios or future tracks.
