The fact that the Ta/ T conversation not revealed to us is a sign that some thing crucial has taken place. That is what makes me feel Ta may be acting and disclosing it to T so that she went along . This has to be a secret and the traitor Padma also has to be fooled. So may be that is why Ta was super harsh. Poor Kumaran sir made a very unsuccessful attempt to literally squeez our eyes for tears for Chaaru. Sorry, not working. We hate her more. Though initially there was some sympathy for her, but more anger towards TA for not being honest with her. Going to the extremes of almost killing some one and making him a captive only gives her the terrorist status.
If at all TA is not acting..
1) He cannot marry anyone until he is granted divorce.
2)C cannot wait for so long to let her willingness towards TA as her timelimit is only till the date fixed for her wedding with KP...If C opens up, TA will realise he is the all time biggest fool.
3) Imagine even when TA is convinced by GW/Lav/C/VR begging, falling in his feet(incase KP is removed from scene) to save C's life, this is the best evidence for T to prove she was right all time..
4) If the case comes for hearing, even though it is by mutual way, will TA tell T doubted about his character and blamed C or will he tell T is mentally ill??? Will it have any hold in the court?
GP/Nitish are in favour of T which is a biggest plus point for T. What if T says C is mentally ill and make GP also say the same?
TA can seem to be a all time loser, but court people wont be so. Even though charu might try to influence people with money, the inspector lady saw what happened to T right thru her eyes, and college students are evidence again against GW on how T got married.
So its all favourable for T only...
LOL, but this is all totally out of question as I deftly believe TA is only trying to make C/GW/Lav confess on their own somehow. Word ku words, amma told, amma told, thirutu kalyanam, etc are just the highlight..lets see...
