Completely agree on the dialogue, it sounded very weird coming from an educated Barrister like Bondita. If someone like Tapur/Tupur said it, would have been cringe but understood. As for the love story and everything, frankly, right now she is trying to make sense of reality. Like a fellow member pointed out, Sumati and Anirudh are her anchors since childhood and she cannot bear to lose them. Yes, it does seem in the face right now, but I'm seeing it more like she just wants answers so she knows what to do next. Till now she was living for 8 years away from all the chaos, and he fulfilled his promise, so she is still untouched by some of this and is innocent.
She will go back to doing what she is destined to, maybe when she gets a rude shock and awakening by seeing the true resultant of the whole dushmani and how it has affected not just the families, but society. Maybe Ani will make her see (albeit by avoiding her or telling her off) that the issue is bigger than just patching up, they have to get the villagers to stand as one force against British Raj at some point and end the other prevailing social evils too.
