Thamarai rants about the rules to Akshara and Niroop.
Pavni, Madhumitha and Isaivani spend the night outside according to Bigg Boss instruction and watch the fire for the night.
Isaivani warns contestants not to use kitchen before she keeps the coin. Later, she gets into a small fight with Thamarai Selvi and Imman Annachi as they didn’t listen to her instructions and cooked extra and also before asking her. Isai warns them not to waste food.
Madhumitha scolds Isai and asks to listen to her since she is also the captain of the house. Isai was seen sleeping once again and this time, Madhumitha is visibly annoyed.
Isai complains to Abhinay about Imman Annachi who is not listening to her instructions.
Later, Imman Annachi questions Isai about her powers for the week. He wants to make sure what is the power of the captain Madhumitha.
The issue gets bigger as everyone talks about their confusion regarding Isaivani’s power and Madhumitha’s power.
Madhumitha says that Isaivani is not listening to her and she is hurt because of that. Madhumitha asks her to think from her perspective. Contestants ask them to meet separately and come up with common rules.
Imman Annachi narrates a couple of situations where Isaivani’s suggestions weren’t logical, for example, cleaning the fridge in the midweek. The conversation gets bigger when Akshara says that Isai leave words easily and talk is very rude at times.
Priyanka supports Isaivani and consoles her as it is Bigg Boss’ announcement.
Thamarai questions what is the use of picking the team for household tasks and a captain if everything is under Isai’s control.
Later, Imman Annachi talks about how Isaivani got the coin, stresses it was team work. Isaivani gets annoyed as everyone is pointing that out every single time when something had happened in the house. She says that she hates it as she wanted to play the game alone.
Later, almost everyone says that her activities and words are rude once she got the coin. Isai moves away crying.
Priyanka, Chinnaponnu, Madhumitha consoles her.
Madhumitha then cries telling that she wasn’t able to do anything a captain usually would do for the week as Isaivani is ruling the house. She feels bad and is deeply hurt by not being able to do anything.
Madhumitha makes up with Isai and then Raju and Imman tries to explain about their issues with her.
Bigg Boss then gives a round. A debate.

The next round for the debate is-
Village members or Town members- who knows the place and uses proper/right words while talking (Idam, Porul, Eval parththu pesaradhu).
Town members wins the argument once again.
Bigg Boss puts a temporary break to the Village-Town round and asks everyone to return to their normal life.
Ciby is seen eating along with Akshara. During the debate, Thamarai had commented about the dressing and the words used by town people, especially, girls. (Adakkam odukkam). This didn’t go well with Ciby as even during the debate. Thamarai tries to sort out with Ciby while the latter was eating. He says that it is her perspective and one shouldn’t judge. The conversation turns into an argument. Abhinay asks Thamarai to wait as Ciby was eating.
