After marriage, Krishna warned his family of the consequences of any plans to hurt Prats while he was alive would lead to a full blown barbadh of everything.
Krishna has stood by Prats on almost all occasions (except fake pregnancy) starting with the name changing havan, averting Amma and SS's insults, court case, coal face-painting, poison sapping to name a few.
Once Amma knew of the fiasco of SR#1 her hatred of Prats has gradually grown into full-blown hatred. Krishna is well aware of how his family members feel about Prats. He has been on the receiving end of a lot of ridicule in recent months as being joru ka gulam.
SS's hatred of Prats began the moment he heard about Krishna's marriage in name only. Even saving Kesar's baby was conveniently forgotten.
The battle lines have been drawn in the Takurs'minds. For now it's a game of cloak and dagger. Krishna does not know of his family's plans to do away with his wife for good. The Takurs know Krishna will always stand by Prats side as long as she is in their lives. She is a liability to them on several fronts not to mention she is not of the same biradari.
Krishna - Hamesha saath dega to Prats, wants SS to change his ways, and Amma to stop picking on his wife constantly
Let's look at the Takur's hidden agenda.
Ganti Dadi - Aware of the family's hatred for Prats, assured Krishna of Prats's chastity, one of the two people who supports Krishna and Prats marriage
SS - Wants to get his son back from Prats's clutches like he is a piece of property since his return to life and be rid of Prats from Krishna's life forever, even kill her if it accomplishes his goal
Amma - aids and abets SS and KN in their plans to end Prat's life any which way she can and get Krishna remarried to a Takur girl, one she can control like Kesar
KN - Is ready to plan and execute Prats's death on behalf of his family, wants to be rid of her for saving his unborn baby's life, its reason enough for him to want her out of the picture forever
Kesar - can blow their cover and send SS, Amma and KN to the slammer for premeditated murder for a very long time, she supports Krishna and Prats marriage
Komal - was eyewitness to a plan for premeditated and attempted murder of Prats, averted the plan, now fully supports Krishna and Prats, is on to her parents' schemes and warns them. She hasn't had a chance to clue Krishna in on her parents' plans for Prats.
Krishna didn't say much but with one simple gesture of reaching out and holding her hand from his hospital bed, he spelled it out loud and clear to his whole family Prats was his jaan and would always be first in his life. SS and Amma are licking their wounds privately and biding their time while keeping their prey within their sights for now.
Who makes the next move? What will it be? Please Bolbo!
