Logically as per the situation gunjan should leave the garg household and the garg,s behind
But I would like to see her stay there to paint out vihaan,s true intentions to the entire garg family and make them swallow their venomous accusations which they hurled at her
Though the reason for her to get trapped by vihaan is very poor and does not serve the purpose at all. The fact she is just an 18 yr old and was given a few minutes before the ceremony to decide by vihaan &also being ambushed by mintu i think she does deserve the benefit of the doubt.
nobody could act politically right other than the 4 drama queens in such a situation
I hope atleast now Rachna would sit back put on her thinking cap and recall all the tricks vihaan had played on her and gunjan,s faith and realize who is the one who betrayed her trust more
Hope she does realize what vihaan actually is and rejects him outright
( am not sure about that though)
The creative team would love to keep her as a weak character all along
