Thulasi told TA in the restaurant she somehow could not like Bhuvana. As some of you said, what she says is from her subconscious. Deep within each of us is the little boy or girl, and the child exactly knows the truth about everyone with whom the person is interacting. Learning based on how I feel about some person with some curiosity helps me improve myself. The feelings within may be buried but they will be still there. That part of T knows all the pains T had in life are due to Bhuvana and so her little girl is angry with Bhuvana.
But how will T be able to ;eave Deepa who had been giving the soothing balm for all her pains even as she was a child and has been continuing to do so? Whatever T tells Indira, somehow things will work out for her.
It simply shows that without T's knowledge there is an unknown link between both of them. She told TA that she usually gives the benefit of the doubt to the person she has comes in contact with and has the patience to sort out things amicably without wanting to hurt the person even though they give her a hard time. But in this case from day one she came in contact with BHU she has this unpleasant feelings about her and she is not sure why this has to happen. Even with Charu T was careful in not wanting to hurt her though Charu was indirectly hinting so many things at her eg. her family background and her low status in the society.😕
