Rukhsar conspires a plan against Kabir and declares in the Shariah Council that Kabir is not fulfilling his duties as a husband and is cheating on her with New Zara. New Zara confesses to the council that she loves Kabir, but they are not having an affair and Kabir did not know about her feelings for him. The council decides to remove Kabir from the Qazi post. Kabir decides to find a husband for New Zara within a month. The new Zara resists this and begs Kabir to marry her, but he refuses.

In the letter, she reveals to him that her real name is Babli and she was posing as a 'Zara' only to con him but did not do so as she really fell in love with him.
The Old Zara is revealed to be alive but is living as a doctor who heals patients through music and goes by the name Nargis. Nargis lives with a woman who took care of her after surviving the accident and she addresses her as 'Ammi Jaan'. Kabir meets her but she denies being Zara. Kabir is sure that she is his Zara, so he requests her to visit and heal Salma through her music. Rukhsar too believes that it is Zara so she fills Salma and Irfan's bedroom with wasps/bees and locks them inside. Zara saves them and admits to being the real Zara. Kabir asks her why she lied and says that months ago after coming out of a coma, she saw him with the fake Zara and thought he moved on.

Rukhsar continues to trouble a helpless Shahbaz who has repented for his sins and reveals to him that she killed Ayesha. Kabir and his family decide to lock Rukhsar in a room with no dangers around her as she is a danger to herself and the unborn baby.
Months later, Zeenat finally spills the beans on Rukhsar and tells everyone that Rukhsar killed Ayesha. Rukhsar tries consuming pills to endanger herself and the child in a bid to save herself but goes into labour. She gives birth to a daughter and hands her over to Kabir and Zara.
