Paddo was confused when she found out about the imported machines for Shamo, also conversation with Radhaji, when radhaji said Rishabh brought madhu to you first for you to see she is alright, so Paddo thinking about that conversation and the imported machines thought this guy RK, I'm mistaken he is not a bad person completely, he cares about me worrying about my daughter's safety, he also cares about the treatment of Shamo that we are all worried and he should be better quickly, so she was coming to repair the relationship between RK and her, to say thanks to him and hopefully they could be a better relationship between RK and the family.
RK told her off, and said he was fulfilling the contract with the treatment, you could argue yes he was as contract is for treatment, but if Shamo is just staying at the private hospital getting better slowly it's costing him more money rather bring all the imported machines and make him better quickly and he can be discharged and in the long run financially it makes sense, but why then to bring Madhu for her mother to see that she is safe, a phone call would have done just as well, so he does care that his wife's family are not worried, also he knows what would happen, that his wife would be told not to run away from home that she made everyone to worry, so again he is very cunning he saw and an opportunity to make madhu not run away when it's tough with him at his house and he used it to make Paddo lecture her daughter.
