Ankita mentioned that probably they didn't want a zashi dance, since they just met. maybe. but zara and indu were there, they could have rishi come to the party and stare at zara and imagine indira and a dance, like aarti imagined her and yash. also archana and maanav performed after the show, so they were performing as ankita and hiten. they could have made rati and summit perform.there have been quite a fe options listed on previous pgs as to why they didn't perform. If not zashi, they could have made her dance solo or with sameer or rail. they are all part of the show😕
