Prabhasa said recently that it's also becoming a force in front of home to marry his mother, who want to spend time with grandchildren soon. He also said that he has nothing if you are looking for a bride to her mother.
With this knowledge, presumably with the permission of Prabha she recently went Prabha's home in a 'pattu saree "for lunch. Many argue now that it is an attempt to impress Trisha and Prabhas mother to recommend to marry.
Well, it's certainly a wise decision to Trisha. We need to see what happens.
