Bigg Boss 15 October 20 2021 written update: Shamita, Karan, Vishal, Ieshaan, Miesha, Simba nominated for eviction

Day 18 of Bigg Boss 15 continues as Nishant Bhat talks to Shamita Shetty about breaking rules. She is upset that he nominated her for the week. When Karan Kundrra says Shamita will go for the task first, Umar Riaz says that she favours Vishal Kotian which doesn't work for him. After some argument, she goes into the room of illusion. There, she gets the option to save one nominated contestant, including herself, to nominate someone else from the house. She chooses to not save herself.

Karan goes into the room of illusion next. He also doesn't wish to save himself either. Afsana Khan wishes to go next but Karan and Shamita discuss she shouldn't go while stating why Vishal should go in the room. During this time, the buzzer goes off and Afsana goes into the room of illusion. Karan and Shamita wish to send Vishal but are also worried about Umar and Simba Nagpal's wrath. Afsana saves herself and nominates Vishal for eviction. Thanks to Afsana nominating him, Vishal cannot go into the room next.

Vishal goes to talk to Afsana and states that he was the one who supported her in going into the room. She talks to Nishant, who is going through people's wrath as well.

Meanwhile, Simba, Ieshaan Sehgaal, Miesha Iyer and Umar discuss if they should go or leave the fourth spot. Simba constantly feels they shouldn't let go of the opportunity but others disagree. Bigg Boss gets upset when nobody wishes to go into the room. Thus, Shamita, Karan, Vishal, Ieshaan, Miesha, Simba and Umar are nominated for eviction this week.

When Pratik Sehajpal asks that someone should have saved themself, Umar starts an argument with him. Karan argues with Nishant because the captain nominated Umar. Vishal and Shamita come together for the commentary as the long night comes closer to an end. Meanwhile, Simba asks Karan and Umar why Shamita didn't nominate Afsana. Vishal also discusses the wasted vote with Nishant, Pratik and Akasa Singh. The Akbar Birbal actor also feels that it would be game over if Shamita nominated Afsana.

The contestants wake up to Twist song on day 19. Tejasswi Prakash hugs Karan and has fun with him. On the other hand, Vishal jokes with Big G. Nishant later asks Karan why he didn't save himself when he is in a game. He tells the TV actor about how Shamita argued with him for picking her over Akasa but didn't save herself either. Shamita asks Vishal why Umar trusts Nishant and later argues with him over the nomination.

Ieshaan tells Miesha about Pratik blackmailing him outside of the house. Ieshaan agrees he played Pratik for work. She asks him if he is bi, which almost irks him. Meanwhile, Nishant confronts Shamita about nominating herself. Their argument continues. Later, Umar also asks Nishant about nominating him or Karan over Akasa. Karan later tells Shamita about having trust issues with someone, hinting at Pratik.

When Miesha and Ieshaan romance, Jay Bhanushali walks in and covers his face. Miesha follows him as Jay jokes 'Kya kya dekhne ko mil raha hai'. To go in the house, the contestants will have to let go of a portion of their prize money. The gas supply in the jungle is closed. Then, Bigg Boss announces the new task - Ticket to Mukhya Ghar.

Shamita-Vishal, Karan-Tejasswi, Ieshaan-Miesha, Pratik-Jay, Umar-Afsana and Simba-Akasa are partners in the task. Nishant is the moderator of the task. The pairs have to decide about how to get more groceries than the other, which will come in through a slide.

Vishal, Jay and Ieshaan stand near the slide to get ready for the task. Umar asks Karan about doing an alliance. Thus, they join hands. The contestants have the option of letting go of Rs. 5 lakhs and going in the house or letting go.

Nishant sends Umar and Afsana first. They aren't able to complete the task. Jay and Pratik go next. Umar comes and tries to null the task. As Akasa goes into the pool to follow him, Simba shows his concern for her. Jay tells Pratik that he won't give Rs. 5 lakhs for going in the house. Pratik tries to convince him that others will go anyway so they should grab the opportunity. Pratik goes ahead and ruins Tejasswi and Karan's task. Vishal and Shamita start as Tejasswi and Pratik argue for what he did. Karan wrestles Pratik and drops him on the ground, which irks Pratik. Jay also defends Pratik. He argues with Jay and Tejasswi, while Ieshaan and Pratik get into an intense fight.

Meanwhile, Akasa and Simba continue their task with nobody interfering. The gong goes off when Ieshaan and Miesha begin their task. Nishant applies new rules to the task. As the captain-turned-moderator inspects the cards, the episode comes to an end.
