Naagin 6 biggest loopholes and Naagin 7 potential story!

According to season 1, there is only one naagmani. The new writers add 8 more naagmanis in season 6. In earlier seasons, nobody can pick up naagmani except when the person who has the mark of Suryavanshi (Ritik, Shivangi), Naagrani of Shesh Naag clan or the ones with Ashlesha Nakshatra picked it up and gives it to them. This rule has been broken in season 6 by the new writers. Pratha and Mahek's father, Anmol and Rishabh picked up the naagmani and swapped it like a toy, the fake naagmani also glow up like the real one. If Vishakha can pick naagmani by herself in the last scene of the season 3 finale, why does she have to wait 50 full moons, manipuled Nayantara to pick it up for her?

Shivanya, Shesha, Shivangi, Ruhi/Bela/Shravani, Brinda, Naageshwari/Bani are from Shesh Naag clan. Shesh Naagin should come from Shesh Naag clan also, not Vasuki clan. If she comes from Vasuki clan then they should called her Vasuki Naagin, not Shesh Naagin.

Instead of making Prarthna Maha Shesh Naagin and casting a new male lead, they should brought back Shesh Naag as the new male lead post the leap because according to Shesh Naag, he is destined to marry a Shesh Naagin, he accepted Brahmacharya because Pratha rejected him, then he broke the Brahmacharya to marry Mahek, but now she is not Shesh Naagrani anymore after she failed to deliver justice to Pratha, Shesh Naag is free now. Pratha and Mahek's grandmother also said Shesh Naagin will marry Shesh Naag, if not Prarthna then they should bring him back in season 7 as male lead to marry a new Shesh Naagin, maybe Prarthna's daughter.

Mouni and Surbhi said they don't do Naagin anymore, so Shivangi and Shravani will not return. But the writers could bring in their children in the next seasons. Mahek has a husband now, they could bring her child in the next seasons also as an antagonist or she could have 2 children, 1 nagative daughter alongside Mahek as the main antagonists and 1 possitive son as the male lead, against his mother and sister.

Though pratha's family is from vasuki clan, they become shesh naagin because they absorb the power from shesh naag's mani. That's why names shesh naagin(explained by takshek in latest ep) and shesh naagin can be made from only those from the 5 vansh - shesh, takshak, vasuki, ...etc(forgot the other two).

About the 8 mani - those were sealed on the statue of singika and power were absorbed by payal (which was on shesh naagin's leg) so no one bothered for their power for many years as they r sealed. And shesh naag's mani was the only naag mani available so everyone fought for it till n1-n4.

For the touch, i guess before it was kept in a sealed area if u check in n1-n4 so only those people could touch it. But if u check n2, after shivangi touched the mani and gave to shesha, everyone even yamini, avantika can touch it. In n4, n3 - vish or vikrant can't touch it as it was again in some sealed area. 

In n6, pratha was shesh naagin's granddaughter, even mehak. So technically it's like in case of bela, her child could also touch naagmani as they r from royal family. Same case for pratha's family too. 

Ad for pratha's father, anmol, they touch it when it is not in a sealed area(they were in meditation). Only when naagmani is protected then only someone from the required criteria can touch it.

 In N1, it was near shesh naag's protection, then 25 years protection due to some nakshatra. 

In N3, protected under naag mehal, then 25 purnima nakshatra.
