It is for Pavitra to decide and accept as to who her mother is. Velu does not have rights to give any assurance to Thamarai.After all these years,why this outpouring of love from Thamarai? The reason is even though she had given up her rights on the child ,she was still the mother with Velu remaining single.Now that Poorna has married and has been accepted by Pavitra she has lost her mother title.
