There are some decisions which can't be identified as right or wrong, Ishita's decision of bringing Param back to Bhalla house falls in this category. But Ishita did NOT take a wise decision for sure. First she met him at night without informing other family members (thus jeopardizing her own safety) just to know whether Param had a change of heart or not! I was like what the hell 😲 So,last episode revealed that Ishita didn't have much of a plan and she did it only for Simmi's sake. But at what cost? She put other family members in danger. Param will obviously hit on her or at least act like that but his main aim will be very different this time and that is to take revenge from all Bhallas, specially Raman. Param will create lots of misunderstandings to destroy peace and harmony of Bhalla family. Param's main duty will be to act as a snitch to destroy Raman professionally. Ishita might think Param's sex offender part will be disclosed to Simmi soon but in reality Param, in my opinion, will manage to keep his name in Simmi's good books and try to harm Raman's business in every possible way.
