Bigg Boss Ultimate! Day 18: Vanitha says Abhirami is an emotional idiot; Thadi Balaji upset with Julie

Balaji Murugadoss's prank did not go well with Vanitha and the latter reacted harshly as always. However, Abhirami extended his support to Balaji and said that he did it for fun. Vanitha, who was in no mood to forgive Balaji, was shocked to see Abhirami supporting him. 

Vanitha advised Abhirami not to be 'so nice' with others and asked her if the latter thinks the former is an idiot. Abhirami, too, shot back by asking 'Do you think I'm an idiot'. Vanitha openly said to Abhirami that the latter is behaving in a stupid manner by unnecessarily supporting Balaji's prank. 

A determined Abhirami was not ready to change her stance and told Vanitha that she doesn't need to impress others and behave superficially in the house. "I know to act only if there is a camera in front of me," she said. Later, during Abhirami's absence, Vanitha was seen telling Niroop that Abhirami is an emotional idiot and that she doesn't realize people misusing her.

She also spoke about the different ways in which people are behaving with various strategies in their mind to win the title. She said, "There are a few who have no guts to face the truth. I prefer to have enemies who poses challenges directly."  

After a while, the college task resumed and Thadi Balaji, who has been donning the principal's character, announced student election. Those enacting students' roles came up with a placard which advocated gender equality in the college. 

Julie nominated Balaji Murugadoss's name for the position of student leader. Both of them started coming up with slogans which made fun of the principal. After a point, Thadi Balaji lost his cool and criticized Julie for indecently commenting on him. Julie was visibly upset and left confused over his criticism.
