Every naagin season is based on the core concept of revenge of partner or loved ones but this season there is nothing like that. I think the revenge part of the season is yet to come. This time it will be an Adinaagin taking revenge on Adinaag for betraying her not once (satyug) but twice (kalyug). This time we might see naagin vs naag. The cheela might be the naagins allies till they resume their hatred for each other (except Veer).
As for the person trapped who might be Veer's mom or maybe not. That maybe a subplot and not the main story.
I don't think Jay is dying anytime soon. He'll find other followers like Mayuri.
Why do you guys think?
