I think the Kheer is meant for Raghav. He wanted Raghav to be out of the way so he can spend the festival with Pallavi and do the couple Pooja's etc. But I think ulta par gaya. I think Raghav feeds it to Pallavi instead and she faints.
Also looking at the precap, seems like Raghav is holding the kheer bowl while Pallavi is dancing so not sure if she fed him before the dance or after the dance. The dance where she faints is different. It has the dandia sticks I think. Im so confused. I guess we will find out soon enough
