I strongly feel tht he has got some evil plan in his pocket... He knows K's obsession for Pratigya n he some how wants to throw away Pratigya from K's life...He verywell knows tht K will not support this dasi idea or taking her for the farmer's debt... He clearly could vision this n he knows already tht K will support this girl n develope a soft corner for her[ofcourse not in the place of P]... so tht she can be close to him n try to forget P in the due course of time... Its his plan... i would say... He also knows if anybody bring any girl n ask K to get married he point blankly refuse...So, he took this way i would say...
Now what's ur take on this...
