While this show began with the primary premise of Shivanya wanting to take revenge for her parents' deaths, I think there's a lot of interesting mysteries that are still not revealed to us.
Firstly, there is person number 5 that she still has to find. I believe it is a lady who is likely Yaminiji as in the flashback there was a person in a sari at the mandir when the snakes were killed.
Secondly, maybe this is something that has already been explored, but why is Shesha so interested in Shivanya's revenge. I understand that she feels her pain as a fellow naagin, but at times her hatred seems to exceed Shivanya's by a lot. Also, when she saw Ritik's poster in the haveli store room some time back, she seemed to harbour a lot of hatred for him too. As an icchadhari naagin, she's definitely a lot older than Shivanya, maybe at least a 100years older - was there something that happened in her past that is also connected to this family?
Coming to the poster of Ritik, I think the haveli itself holds a huge mystery. When Anky was explaining to the children about the posters, he hesitated over the torn one before saying that it was his own. But it was Ritik's poster hanging there right? How did that poster end up there?
And talking about the haveli, it is quite certain that he was simply a gardener, hence he could not have been owner of the haveli before. Did he steal it by killing its previous owner? Was Yamini actually the owner's daughter (since she called him mali kaka)? And, if Anky is not the actual owner, then how are those ancestors related to him? How is Ritik's poster there? Is Ritik even their son?? (I think he should be, since they show so much concern for him) Was he some raja in his pichle janam??
Too many questions, too little answers!🤪 Either that or I'm thinking wayyy too deep into this😆😆
