They show antara and the terrorists still on the scooter and one of the terrorists plants a bomb near a huge building and rejoins them and they set off elsewhere. In another checkpost the terrorist who is driving the scooter seems confident that they will get through thanks to the other guy's 'beti' (sic) and they almost do except that the police inspector there seems to recognize the guy who's driving the scooter and antara says bomb and so the scene shifts to the police station where they are bashing up the guys so that they will cough up the place where they have planted bombs. Since they don't the police inspector starts interrogating antara very roughly and she starts screaming and right then aditya, vikram, abhi and billoo walk in. They say that antara is aditya's daughter. The police inspector is not willing to buy the story and wants proof. Aditya quizzes antara on whether he is her father or not and she repeats papa papa. The inspector is still not convinced and says that she had called one of the terrorists also papa and takes them to where the terrorists are in a messed up state. On being quizzed poor antara points at turns to both aditya and the guy saying haan papa haan papa. Then Vikram explains about autism to the police inspector and says that she just repeats what she hears, yes she repeats a whole lot of stuff but without understanding the meaning. They also prove that she is indeed aditya's daughter with ID proofs, Dr Vikram's case book and Billoo flashes out antara's school ID card from her bag and she is finally allowed to leave. She asks for paani paani and when paani is produced in a bottle she moves back in fright and abhi patiently explains that she has been trained to drink paani only from a glass and so associates the word paani only to a glass.
By now the police inspector is at his wit's end and orders them to leave.
Once outside aditya is looking sad. Vikram understands his anguish. His anguish is that he has waited all these years to be called papa by antara and was very hopeful seeing all the progress she had made in six years but now realizes that she can call anyone papa. Though abhi had tried explaining to the inspector earlier on that she must have called the guy papa because they had drilled it into her. Anyway aditya is feeling disappointed and Vikram encourages him saying that there will be more progress but it just takes time that's it.
I kind of didnt get the precap completely but Vidya has some issues with antara and when aditya protests that she was with him and abhi also argues saying that she is also a kid just like him, vidya shouts at him saying she does not want any more arguments.
Hope the update is not too garbled. Am not well and this is the best I could manage. In case I have left out anything you may please post the same in your comments but I think I have gone over the main points.
