Okay, Dhara is such a problematic person. By which angle she seems like a matured person who knows how to handle stuffs?
They should prepare Raavi for the forthcoming, they should tell her what's happening, atleast give her a hint if you can't tell about the whole situation.
Even when my Nanu's health was detoriating, some advised not to tell this to Nani, but my mom, mama and mami all were very clear that instead of giving false hope and sudden news, it will be better if they tell her the real condition so she's prepared for everything.
And even if they want to hide it, they seriously think with all these weird behaviour Raavi won't find something fishy at all?
I can't understand Dhara's obsession with sending everyone to their room, sab room me jao, tabhi to nai akele aangan me hongi or camera charo side se mujhe aayega
