Virat and BK want things to go back to how it was pre-leap. Keep Sai as patni for the "needs" and romance while Patralekha gets all the emotional support. And since kids are in the mix, they know Sai won't take any decision against them like before leap. So it is all well for them. Who cares if two women, two children and a whole family is put in crisis because of it. As long as ghar ka beta gets pati ka sukh, emotional support and two chiraags, everything is well in VC and BK's world. And shippers will be happy that a woman finally understood what her only purpose in life is (be a mother and wife to a cheater) and live "happily" with her "family".
i just want to watch this kind of performance again
