Today has been the day that saw many splits in the relationships of the members of the house. The day began with the grudge from the weekend episodes. Rio started giving Anitha the cold shoulder because of the continuation of unwanted arguments between them. He was talking to Ramesh about the same.
At the same time, Archana became angry with Som. According to her own words, she was upset with Som because he was closer to Anitha than anyone else, and he should have tried to clear Anitha's misunderstandings with Rio just as he was trying to explain himself to her.
Another major friendship break happened probably between Shivani and Bala - after his outburst at the nomination task about the "Kaadhal kannai maraikirathu" statement, Shivani complained Bala was not acting normal with her, and hence she did not 'disturb' him thereafter.
This word might have triggered Bala, for he said - "Okay you did not and don't disturb me hereafter" and walked away. They are seen walking away from each other.
