What I think that Paro was making some khada and as usual Rudra will think that Paro has mixed some poison and Paro will first eat and then she will make eat that khada to babuji.
If my prediction is correction I think Rudra will will be emotional as his father will not be with him in the award function and in the end when Rudra will not be able to finish his speech and at that time Paro will bring his father😊 and then after seeing his father he will be able to finish his speech😛.
This will be the time when Rudra will start believing Paro😳 and both will try to solve the burning as well as Rudra's Mom mystery.
