Was he unduly rude to his mother? I think no. He was angry even with dadisa, basant etc. and he slowly realised Sumitra's part. Sumitra made matters worse by defending her stance. She experienced Jagya's behaviour when he was madly in love with Gauri. At that time he did not listen to anybody.
Sumitra made even the unflappable Bhairon angry. Bhairon explained to Sumitra and asked her to understand. He does not know that ratan was only a bahana for sumitra to wish ganga out of the haveli. Bhairon showed what a great actor he is. He just looked at Sumitra with that searing intensity.
It was filmy scene, ganga soaked in the rain and Jagya following. But it looked good.
Hope all of them wont catch cold.
When Jagya gets angry, none can stop him. He is one angry young man.
