Alta sequence based on my limited bengali understanding was basically - Emon was asked to do this alta ritual. She refuses initially. Theres some big family drama about it and then eventually Ronos mom convinces her. Later Rono comes home and eberyone instigates him. Hes almost ready to launch at Emon again but his mom says wait until you see everything for yourself. And when emon comes she shows that she did apply the alta. Rono's mom says that she only agreed because she told her thst the ritual would ensure i guess "prosperity" for Rono. Rono shocked that Emon is also concerned about him. Later theres a nice scene in the room. He is niharofying her in the room as she sleeps. When she wakes up they have some sweet moments including remembering her father and Rono even feeds her dinner just like her dad did.
KD formula i think was like 1 nice/nostalgia episode for every 4-5 episodes of fights and MUs!
I really hope they dont reduce Sairat to the same thing where they start giving just 1-2 token scenes but fill the rest of the plot with just their regressive drama - family screaming at each other and couple having MU and fighting :(
