Agree ! more than Mangala, it is anandi who needs a mental check up followed by rigorous treatment.
At least mangala's state of mind is understandable. The child whom she loved for 12 years is snatched away from her.
But anandi is forever unsoud and unstable. When she took her sick infant to a dangerous place, Alok, Ira and Meenu should have got her admitted instead of shouting at her and holding her responsible.
