Rudra will imprison Paro as part of of his agressive tactics in getting out information from her.
Ofcourse nothing comes out of her for she has no clue about any of Thakur's activities. As we have seen earlier Rudra has been pulled up many times for his ruthless ways in dealing with his enemies...and the same will repeat. He will be pulled up for manhandling a woman and imprisoning one without enough evidence.
At the same time Paro is abandoned by her side of the village...as redemption for his mistake Rudra's seniors will make Paro his responsibility which of course he hates.
There is supposed to be a chacha and his wife who might provide her shelter. She would now be on his side of the village or where the BSD families live...
