Shivam doesn't know the truth

May be Mannu, Shivam and Abhimanyu think Anandi and Ganga are cousins. Mannu and his brother call Anandi 'Maasi'. Anyhow only this is possible at the moment and Jagadish can't be Anandi's brother so elders must have connected it this way.

Yes, Shivam doesn't know about his twin sister.

She told Amol that he can call her Kakisa by that coin J became Kakasa to Anandi's kids

Mannu and Abhi calling Anandi Mausiji

So it does look like Anandi and Ganga are more like sisters.

Which I guess must have stalled the embarrassing questions for a few more years.

-----------------

But all the same it would be better if Anandi tells Shivam that he had a twin sister who was kidnapped and they are still searching for her just like the way Mannu needs to know that he has two fathers and the one who is raising him loves him like he is his own son without going into too many details.

There is no point telling them all the details which they can't make sense of at this time and confuse them.

wat shud she'd told 2 amol & shivam 2 call her??2 call her mamisa or D or nanisa.

great logic & great defenses 4 Aji .

Aji kare toh raasleela koi aur kare toh ckt dheela.
