Lock Upp day 12 written update: Anjali Arora tells Munawar Faruqui that Karanvir Bohra asked to fake a relationship with her

Lock Upp day 12 also begins with Tehseen Poonawalla and Payal Rohatgi being the early birds, just like day 11. Joining them is Shivam Sharma. Tehseen and Poonam discuss the rules of the task where Team Orange had to serve Team Blue. Payal gets upset since people point fingers at how she cooks food. The discuss then continues between Tehseen, Sara Khan and Karanvir Bohra. Nisha Rawal takes the discussion forward.

Sara later confronts Payal. Karanvir also passes a comment on how Payal has a problem with everything. Payal blames it on Shivam and refuses to talk to him at all. Shivam tries to explain his stance and Payal does hers. Sara then asks Payal not to be her mother which leads to an argument between the two.

Karanvir and Munawar also discuss about Payal and say that she flips and tolerated her for the game. They say that now people can see her real face.

Team Orange's punishment is over and even Team Blue can use the kitchen to cook now. Sara breaks down in the middle of lunch time. Nisha and Shivam come to console her. Tehseen joins in too.

Nisha loses it on Anjali Arora as she interrupts Nisha's conversation with Munawar Faruqui. Munawar came in between Nisha and Payal's conversation on wasted food. Later, Payal and Sara make-up with a hug.

Anjali tells Poonam that they should tell Tehseen about how he should wash vessels. They then try to confront him but nobody owns up to washing the vessel.

Karan Kundrra enters the jail again. He tells the inmates that their show is the second highest ranking show pan-India. The inmates have to go to a place with Karan. Team Blue goes first, with their heads covered like prisoners. Team Blue sing their anthem during the ride. Team Orange follows and the two gather in the same area - the Atyachari arena.

The Atyachari game is 'Oonchi Hai Building'. The teams have to use building blocks to make a building. Siddharth, Karanvir go against Saisha and Shivam. The task brings in everyone's competitive side since they first have to fight to get the most building blocks and then, build their own building while protecting it too.

After Karan's motivation, Siddharth and Shivam get into a physical fight. Karanvir and Saisha go head-to-head too. As Shivam throws chappals towards Karanvir's block, both Team Orange and Karan Kundrra go against the act.

The fights between both the teams intensifies. Munawar motivates Siddharth to ruin Saisha's building. Team Orange wins the round since Saisha's building falls apart. Jailor Karan praises everyone for their efforts. He tells Shivam that agression needs direction, which was lacking in his case. Shivam, in turn, apologizes and says he will improve. Karan then promises a gift for Team Orange, who have won the task.

As they come back to the jail, Shivam talks to Siddharth about how he got hurt during the task. The two were seen properly bonding for the first time. Later, Shivam flirts with Sara saying her food is cure for everything but she ignores him.

Team Orange has to send someone to the jhol ghar. Payal comes running and then agrees to send Siddharth. The two then look for Karanvir. Anjali asks Siddharth if they can send Karanvir or Munawar and he says he doesn't mind. Eventually, Munawar goes in the jhol ghar.

Munawar, Poonam Pandey and Payal motivate Saisha who feels low because her team did not motivate her before or after the task. Meanwhile, Anjali tells Munawar that Karanvir wanted one-sided relationship with Anjali, from her side. Munawar teases her instead. He then says Karanvir is playing a smart game by maintaining relationships with everyone. His advice? To not play the game but enjoy the journey so you automatically become a part of the game.
