Ishita went to the party with Mr and Mrs Bhalla. Yet, when she storms out of the party, Ishita's red car is conveniently parked right outside the hall. Even if we are to think that the Bhallas rode in Ishita's car on the way to the party, it does not explain how their car miraculously appeared for them and Simmi to return.

On the way to the party, Ishita had on her marriage chain, but on the way back, it miraculously disappeared from her neck. I hope that Raman found it while looking for his bracelet.
