Day 80 starts with Suyyash questioning Prince about his opinion on Nora’s feelings. He tells him that while Prince used to be involved in all household matters, after Nora has come into the picture, he has distanced himself and he is aware that it will work against him. Prince tells him that if Nora’s feelings are fake, she will not be able to hide it for too long and either way, he will not let it affect his game. Later on, Nora tells Prince that this could be Suyyash’s game plan too. Priya tries to sort out her differences with Nora about their fight in the morning. Nora, in turn, questions her, saying that she should have told her when she knew about it. Kishwer joins the conversation and clarifies to Nora that the discussion was out of concern for Prince and her name only got dragged in it.
In the middle of the night, in spite of being warned to not tamper with task-related properties, Prince changes the position of all the diamonds in order to confuse the thief team. After the housemates wake up to ‘Romeo Naam Mera’, Priya decides to put oil on the diamonds so that the diamonds slips out of the thief team’s hands when they try to teal it. Bigg Boss tells them that their actions will have consequences on the luxury budget. The task commences once again and Keith feels that Suyyash, as the supervisor, is being partial towards the police team.
In the afternoon, Priya and Rishabh get into fisticuffs even as he tries to escape from the jail. Getting a little aggressive, Rishabh throws Priya’s shoes away and Priya in turn, breaks the pot of water meant for Rishabh to drink from. When Keith gets arrested for stealing a diamond, Rishabh is allowed to leave the prison. Keith further tells Rochelle that during the task, he does not consider her as his girlfriend and she should not get influenced by her emotions either.
Meanwhile, in the bedroom, Priya and Mandana are seen taunting each other. While Mandana calls Priya a ‘little mosquito’, Priya in turn, calls Mandana a ‘massive dragon’. The girls get catty even as the task continues. Keith is successful in annoying Rochelle by yawning and pretending to sleep while she searches him. When he disowns her as his girlfriend in front of everyone, she feels disrespected and gets angry. Rochelle then tells Keith that he will have to face repercussions for passing that statement. However, after the task, love is in the air once again as Keith immediately hugs Rochelle and refers to her when he says, “Mera diamond toh mere paas hai!”
In the night, a different side of Rishabh-Priya-Mandana equation is visible even as Rishabh and Mandana talk about how Priya is a horrible game player. The taunts do not stop even when Priya walks in to make tea. Ignoring the duo, Priya out of courtesy asks them if they would like some tea. While Mandana tells her to stop being fake, Rishabh tells her that she makes horrible tea and he would not like to have it. After this, he requests Suyyash to make tea. Suyyash obliges but tells Rishabh to back off for being mean to Priya over cooking.
