My take on current track

Since yuvi is youngest child in the family i guess mahir and kuhu are kids of andy's first wife.

I have a strong feeling that mahir will trust bela this time coz bela has justified herself saying that she only punished those who has molested her that night and she didnt cause any harm yo bultu n pratham as they were innocent and since yuvi is also back mahir will definitely suspect the situation

If Real Sumi would have been sister of this purple Sumi she would have mentioned today.

Mahir is not this purple Sumi's son.

So what I feel Mahir is real Sumi's son.

And real yuvi who is coming back is purple sumi's son which she hide from vik

I am even doubting is vik really purple sumi's son

Mahir Adi and Pratham is his son as of now it seems

Kuhu I don't know😕

Sumi doesn't bother to tell Viku that he have a brother?

It's a mess. Sumi says she had to have children, implying that Mahir, Yuvi and Kuhu are all hers but then she wants Mahir dead and she ruined Kuhu's family. Even if a mother kills her daughter's husband - fair enough, a son in law is not usually a blood relation - but how could she order someone to kill her own granddaughter? W*F. So Yuvi is the child she was forced to have with Andy? Why bother? Andy's real wife already had Mahir and Kuhu. Naagin Sumi didn't need to have more children. Poulomi was happy to provide more.

As it stands, it goes like this:

Naagin and unknown man - Vikrant

Andy and 'real' Sumi - Mahir and Kuhu

Andy and naagin Sumi - Yuvi

Andy and Polo - Pratham and Adi

What a nice blended family. Even the Kardashian-Jenner clan aren't this messed up!

Edit: I read somewhere that there was a flashback to 100 years ago where naagin Sumi had the same face she has now. She can't be the twin sister of real Sumi unless real Sumi was a naagin too. That means Mahir and Kuhu would also be naag and naagin. It would also mean that Mahir and Kuhu are Vikrant's cousins and that Yuvi is both half brother and cousin to Mahir and Kuhu. Wow.
