I like to see TA as a hero who can make difference in the life of the people who are around him by being a more loving and understanding person. Didn't he try to be that type of person earlier when he did thiruttukalyanams. What are his possibilities?
1. He can encourage Thulasi to talk back to his mom taking Sudha or Kalyani as examples. the encouragement becomes necessary because when GW speaks back to her with all venom, Thulasi may like to have his support.
2. When Thulasi was seeking help in doing something for Deepa who is not happy, he can try to address the concerns of Deepa with more understanding and gentleness and not with the indifference he showed when he told Thulasi not to talk about Suchi.
3. He was seeing Suchi speaking arrogantly to Shyamala and he knows Shyamala would have been hurt. Whatever be the profits he was getting because of Suchi, the way she was speaking was enough for anyone to spot out that something fishy was there for Suchi and the long term benefit in any office is possible only when there is friendly atmosphere and this atmosphere was spoilt by what Suchi was doing. Therefore he must have supported Shyamala then and also admonished Suchi for behaving arrogantly.
