I think I said this before. Khushi and Arnav know each other before she got married. Is there a chance she married Armaan thinking it is Arnav?
Because, if they can be differentiated, then she would have recognised Arnav after Armaan's death. If they can't be differentiated then, there is every chance she thought she is marrying Arnav, unless she was already informed that it was Armaan she was marrying and he had an identical twin brother called Arnav.
The other thing is why did Anjali say "Khushi is the only family they have left now", when she was convincing Arnav to take Armaan's place in the Prologue?
Ok Anjali noticed the special emotion Arnav felt for Khushi. It will not look nice if the family acts on Arnav's emotion and ask him to continue the charade because he had fallen for Khushi.
It is good that Avni has earned a place in Khushi's heart.
In any case, after giving birth to her baby, Khushi should be informed about the truth and then she should be allowed to take decisions about her own life. It is unfair for Khushi to think Arnav as Armaan forever and unfair for Arnav to forever known as Armaan.
Cheers......
