Honestly, the last couple of episodes are sooo boring. All they do is apply sindoor and doing pooja, do they not have company/business to run? Anyways some theories for upcoming episodes based on what has happened in ITV show history:
1) the sindoor series goes on for at least a month
2) Purab learns the truth about Sargam either from Rohit or sees the Newspaper (because Sargam is too scared to tell anyone)
3) Hans ends up winning by telling everyone the pregnancy truth and Thapki leaves the house (so no confession)
4) Hans leaves and comes back with Armaan as his fake wife, so she can stay in the house and get Purab, and Armaan can get Thapki
5)Thapki is kicked out the house and Purab divorces her (prob because of VD or Hans) comes back as Armaans wife
6) Purab finally starts suspecting Hans singing
They can do any of the above as long as they don't kill of Purab's Character because, they are barely showing him!
Which do you think will happen?
