Hi MJ
Just going by my overactive imagination so take my ideas just that
I thought that there were 2 theories
A) Arjuns secret identical twin
B) KP's 1st wife if he had one who is locked up
But just seen BTs as @ Dihiva said and it seems that the dancer is someone hired by Navjot &KP maybe to makeout Megha is insane because there will be no dancer and no secret room so when truth of Goldie comes out they can say both Megha & Goldie are insane & imagining things
I do think however there is another subplot going on that does involve women in that household becoming trapped & that Megha will.unfold this
I have a feeling it might be the 1st choice and perhaps, something corroborated to Arjun most likely. Let's see.

.....if one of the child comes out LGBT....and if the fact is kept hidden from society toh it makes someone orthodox
still it's a big topic ig.....

.. but we have to be on guard.. kuch bhi ho sakta hai
