The colonel: smitten
Naina: predator
Bua: a very helpful foe for now
Cousin: no match for Suraj
The colonel finds his mobile on the floor and also finds the device, he orders Deva to bring in a computer engineer, bua comes and blames Suraj, they leave without noticing Chakor.
Chakor signs to Suraj, he goes to talk to her, she tells him what happened and that she needs to come up with a plan to sneak into the colonel's studyroom. Naina's cousin comes to them and he talks sleazily about Chakor, Suraj gets angry and tells him to leave, he leaves with a friend and Chakor tells him not to get angry. The cousin then goes to talk to Naina and Suraj observes them, he tells Chakor that he has a plan.
Imli is beating hard on the door she's shouting for the nurses to let her go, she starts hitting her head to the door, she wipes the blood when the doctor comes. He tells her she can't leave until a family member comes and they can't let her go because of her criminal past. He tells her she had harmed herself and they have to start her treatment from the beginning. They leave and she starts throwing things, she's angry Chakor revealed her past.
He goes and beats the guy for touching Naina, Chakor sneaks away during the fight. Naina intervenes and tells him that he's her cousin, Suraj apologizes insincerely. Bua doesn't like his behavior but the colonel is impressed, he says he'll protect Naina.
Naina starts to scold Suraj when she notices that he bruised his hand, she takes him to her room to dress his wound, she tries to kiss him but Suraj escapes by shouting in pain because of his injury, she then leaves the room.
Chakor searches the library but can't find the device, in her frustration, she hits the desk then she notices the box containing the device. She takes the device and leaves but she sees Naina coming from another corridor, she tries to leave the other way but the servant is there, she hides behind a stand.
Suraj comes behind Naina (how convenient), he notices Chakor, he turns Naina around and starts to talk to her while signing Chakor to leave. Nain is about to turn and come face to face with Chakor, Suraj holds her by her waist and makes her face him (I think these scenes are punishment for Chakor for making Suraj take up the mission). Chakor looks on and finally leaves.
Suraj tells Naina that she's innocent and he isn't good she stops him from talking and wants to kiss him, bua comes from the direction where Chakor was hiding and saves Suraj. She scolds them both, Suraj apologizes and takes the blame. Bua says she hopes her brother would see sense and stop the wedding. Suraj is secretly grateful to her. They leave to the party.
Naina's cousin comes to shake hands with Suraj, Suraj apologizes and hugs him, he talks rubbish about him and Chakor in Suraj's ears. Suraj pushes him to the ground and threatens him while helping him stand.
The colonel finds the device missing and tells the guests no one will leave until they get searched.
