Okay fellas, so I know that we are seeing very straightforward and simple things as now, with regards to the 3 main characters - Jai, Bani, and Veer. But show ka naam Naagin hai after all. So yeh bhi to ho sakta hai that all this innocent Bani is a charade orchestrated by Adi Naagin herself. Hypothetically soch kar dekhte hai.
Bani - dukhiyari situation, orphan, majboor behen, cinderella ke step sisters jaise cousins, aur evil stepmom. Kya scene hai. Kisi ko bhi lapete me le le, especially dushman ko. So here goes my theory.
Adi Naagin Naageshwari totally remembers her previous life. Uske previous life me bhi uske 3 naagin friends thi, agar kisine dhyaan se dekha hai to. And in present also, she has 3 sisters. All these 4 are the 4 naagins. Just like Veer aur uski puri cheelon ki fauj hai, Adi Naagin Bani and her family are all her fauj.
Noor's death could be a setup. Noor and her family could easily be some other shapeshifting nags and naagins who are helping Adi Naagin set up her trap for her enemy. Now, here enemy could mean many things.
If I wanted to make the story interesting, I would show that Adi Naagin in Kalyug had been loitering around the cheels for 40 years to gain full information of her enemies. And also hovering around Jai aka Hriday. Remember, Balwant said that Veer's mother was killed by an ichchadhaari naagin. So while doing her reconnaissance, she comes to know that Hriday was working with the cheels and Jai remembers his past (probably??). She also comes to know about Veer's kundali prophecy and she hatches a plan to use Veer to take revenge from senior cheel clan and Jai by marrying him since she knows she is the enemy Veer is meant to fall in love with. This could be really interesting route, if taken, OR
Going by EK's typical standards, Adi Naagin Bani decides to marry Veer to take revenge on the cheels for what happened in the previous life and safeguard her lover Jai aka Hriday. And then after taking her badla, she will live happily ever after with Jai, but things don't go as planned.
Technically what I jotted down is very similar to Season 1, but aisa ho sakta hai. Or jaisa hum dekh rahe hai, cheeze kaafi simple hai aur Bani ko abhi bhi koi idea nahi hai apne Naagin hone ka.
Btw, do share your views on my theory. Would love to know what you think about it.😊
