nupur looked so confused and in such a innocent manner that she never knew mayank.neither happiness nor anger was seen on her face.she is just perplexed is what i feel.
i strongly feel that its def memory track where she forgot everything including morena-bauji-bui-gunjan etc.i think she only had herself.
in order to have some masti,dhammal and new opening for mayur this is the only possible way.
