Maybe when bhua dadi will say to pandit ji to start the pooja then navya will feel bad for anant and will decide to bring him back. So she will go to mishra house to get anant.
When anant will see her they might hug each other as they will meet after a long time. Then anant will ask navya that why she came here as this can ruin their plan. Then navya will say that she doesnt want to spoil his birthday for any plan. So, she has come to take him back to his house.
