So Far the GW gave hopes to Charu. GW & TA were praising her and GW always kept pitting down Thulasi which made Charu happy and her psychoness stayed in control . Now people in her house praising Thulasi and putting her down by comparing makes her furious . Slowly Nithesh & Lavanya will start praising Thulasi. I don't think Lavanya will suffer in her in-laws house through her MIL though she deserves to be. But now i feel Lavanya will suffer from Charu's indirect tortures which might lead to a bad impression towards Lavanya from Nithesh's family POV. There's another possibility here which is Charu can directly talk to VR after he get released and might make sure that he never says yes to bring Nithesh& Lavanya.
These days Thulasi is way more smarter than TA. I guess periappa noticing Charu's behaviour while they praise Thulasi will get linked with TA sooner because she fainted at TA's house while TA praised Thulasi. Charu might call and complain GW that Thulasi went out with Deepa & its not Narmatha and she might say the meeting with periappa but wont disclose the matter that they talked, then periappa might call TA directly, GW's plan will fail on trying to create a fight between T&T.
