ok so the nandas were a big family, and ka was the basis of the show. kavya and anjali got married and on thier reception they invited paro and then when om and paro were not speaking to one another, and pallavi tryin to kill paro, anjali took a bullet for paro and saved her. and then anjali gave paro the box which had oms killers info on it. thats paro and her connection to nanda, and i think they mentioned something about oma nd kavya and being busniess partners.
and pammi, well pammi wanted kavya and so she wid the help of kavyas evil mom created misunderstandings between teh two and ended up marrying kavya. faked and pregnancy te same time anjali was pregnant, stole anjalis baby and anjali was told her baby was still born and pammi called the baby hers. things happen and pammi fell in love wid the kid and for the kids sake brought back anjali and kavya and fixed everything. and then ekta ruined everything by killin kavya
turns out pammis bro killed kavya but i dont know what kind of connection pammi has to paro, maybe she took chotu cause she felt alone and chld deprived or something, i really cant say but there oyu have it.
