Okay I've few things to say about this episodes, this is only my perspectives, and not any review, feel free to disagree happily.
Firstly I loved the opening of the episode today, kudos to the makers for giving such an important message through Ani, while keeping it historically accurate, because following the Industrial Revolution, the British Government indeed did propose some policies and acts to control air pollution in Calcutta and its surrounding areas, that was called the Bengal Smoke Nuisance Act. So yeah 10/10 there.
Secondly the Rudhita shot and lightning up the diyas was beautiful, with RTM in background, it was very symbolic, as if a hint that in future they'll together remove the cobweb of ignorance and social evils by lightening up the lamp of education for all.
Thirdly the Guru Dakshina scene seemed to me a hint that in future Ani will send her away for further studies without her will, not only for her education but also because of his own conflicting emotions, because he'll fall in love with her by then but will not be able to come in term with the same.
Also Bondita will take his name A se Aniruddh with pride and joy in future, it's also given.
Chalo my blabbering ends here.
