What she does is not harmful for Radhika and indirectly helps her. She has reminded Radhika about her training and education and this will make Radhika think and solve the problem herself how to get her KK in a way by not going against anyone and quietly plan her strategies and Chanda has also revealed her mothers plan's and I am loving the way things r moving.Looking at the precap I am sure Kanha may have burnt the chunnar or Radhika remembers the flute which KK plays.
