Thapki has kept a fast without wanting to. She cut her lip which lead to her not eating. She's done the rituals, her and Bihaan have had a fight. She can't eat the sweets the other ladies ate because of some reason I didn't catch. Basically though she's at the table and she ends up drinking form a glass of water Bihaan has just taken a drink from. And he's standing in front of the fan trying to eat cotton candy, a piece of which flys away and ends up in Thapki's mouth.
Folks, this is sooo good for Thapki/Bihaan. I'm pretty sure there's an eye lock and they're trying to stay away from each other but events constantly conspire to bring them closer.

The interview where they explain the sequence being shot is in the second video. The first video isn't super exciting but worth a watch if you want to see them shooting the sequence.
