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
