R is not begging for love or to take her back but she knows how to make Mohan do what she wants,she knows his weak points,knows if they fight will end up with a good result for her. Thus ready for rounds,happy this time. But if all she wanted was to beat T with her own weapon (T couldn't fulfill her wish&force M to tie mangalsutra with R looking at them;R may wish T to see them getting married and preferable remain silent) was a foolish idea. Mohan needs his time to be ready to face any consequence once T knows R is his wife. He can still be taken back to guilt zone for the moment.
But with such
then revealing too early to viewers (without maintaining some mystery elements) that this new T knows everything about R in advance before entering into the house, so straight to point behaving as R's enemy and hence
too much negativity again..
Let it remain as her memoir.
