Now, Tulsi should attack Tanya, Tripti and Damini; with the first target on Tanya, because she seems to be the gang leader. Her marital life should be destroyed with Nandini coming back and slowly seducing Karan; Tanya will break to see this
As for Damini, let her retarded son suffer and she will suffer
For Tripti, we have loads of things to do against her; first and foremost, just shatter that fake marriage between her and Sahil, here comes Ganga to the rescue! and that girl that works with Nakul; make her marry him and bring her to Shantiniketan; then she can abuse Tripti.
GO TULSI MATA!! I didn't like you for the past 2 months, but I am totally with you now!!!
