I read that "krisna Tulsi's mistake/wrong choice makes Tulsi's return into SN".
I was trying to find this article from yesterday,but i couldn't.
I Guess :
Tusi will see all her family members in Haridvar.(but no one sees her).
Tulsi will be disturbed...
As usual Krihna Tulsi asks her the reason,But this time Tulsi tells her everything(Flashback).
Then Krishna Tulsi enters SN as Mayank's wife.
Meera,mohini, Tripthi,Bhoomi & Manthan hates her.Bhoomi's attitude will change later(+ve).
Finally Krishna tulsi will succeed on exposing Meera(may be with the help of Karan)
Tulsi will return and Unite Virani parivar including Business(Tripthi will be kicked out,Ganga returns).
* Definetly Tulsi Doesn't want to come back before the truth of Meera(Murder of Savitha) Exposed in front of Mihir and Family.
