I Know it is late but...

Chaturi, after meeting Ishwar Kaka by chance in market, enquires about RK. Ishwar Kaka fails to identify RK even from his photo which Chaturi was carrying. Chaturi got to know the truth about RK, that he is an impostor, and feigning that he had come from Chaturi's village.

She spots Meena on road and tells the truth, asks for Bhabo's number so as to call her and inform about RK.

Meena was unwilling & avoiding Chaturi, and pushed her in the temple stair. She fell down from stairs, and was unconscious, allowing RK to easily kidnap her. Chaturi hadn't revealed this to Bhabo or Sandhya, so she is blackmailing Meena. Meena pushed Chaturi (from the staircase) and got her injured, giving RK a chance to kidnap Chaturi without any resistance.

Now Vikram asked Chaturi that what happened after she went to the market & what Rk did with her. Chaturi was about to spill the beans about Meena's deeds when Meena hushed her up, so this blackmailing chance Chaturi got.

Hope I have answered your queries. 😊
