With Babuji having an accident and maahan Baa complaining to her son that Anuj was rude and that's why Babuji left, the next part is obvious.
Irrespective of how much the annoying oldie is hurt or not, the loudspeaker son and screeching mother are gonna come down on Anuj and Anupama and as usual, Anupama maata will only cry "mere babuji" and not stand by her husband and say baa was on the one interfering. She'll start with lets focus on babuji for now, then remain silent watching her husband be insulted, then say she'll keep baa and babuji till he is fine, that would shift the loudspeaker also in the house who'll daily taunt the slave as she works hard for her babuji, which will make Anuj also start pitying her and the poor man would blame himself for being a free ka driver and give his wife, daughter and house to these good for nothing freeloaders.
I cant call her a maid because I was brought up being taught to respect everyone for their work and she isn't respected, so am gonna use the term slave only for her who were historically not respected and treated like she is by her family.
My mother left her in laws when she was disrespected, along with my father, but both took care of them in old age, without being doormats, and yet there are times when we felt they were prioritizing others over us and they would balance it out.
