i am yet to see what punishment she got when she utter those words becos my brain was dead while i watching it...death is not a punishment
shivanya loose her powers the moment she consummated with ritik
shivangi turns into a new naagin the moment she consummated with rocky but thats another story that she realise it late in jail,she did not loose her powers that was the hint in N2 and we all suspected right rocky was a naag
punishment is right on spot in naaglok if consummation with human...death was plan by the evils otherwise Behir would not died and here we are talking abt naagrani of naaglok so double punishment
even the book shivanya was reading...the naagin karuki(forgot the name)was punished right on spot after consummating with a human but the story was highly ignored
Perhaps what she meant by that was ill-fated relationship of having her husband died in front of her, having her child died inside her, and dying herself. However, to be honest, when is N3 ever logical; it went down the drain after Naagin revelation episode.
