I always used to think that Bela was the weakest of all the three Shesh-Naagins but Brinda's actions proved me wrong.I can understand her predicament of being this new Naagin but even Bela could see through the manipulation of Vish and Vikrant.Bela inspite of not being Mahir's childhood buddy could figure out his innocence and real love for her why can't Brinda feel the same? Dev was her childhood buddy right so without doing any secret investigation on her own she wrongly assumed Dev to be this chief culprit.
And it seems Brinda's Naagin secret is out even before her revenge has properly begun.Today its Dev tomorrow its gonna be Dev's sister.Then who's gonna take her revenge? Vish kya? Vish is clearly manipulating her and Brinda is blindly trusting her.Bela might have been this weak Naagin but she was no fool.She never blindly trusted Vishakha.Bela was sharp.enough to listen to her mom's advice and figure out the evil scheme played behind her back.
Now Manyata is not there to guide Brinda agreed but Brinda has to learn to deal with her problems herself before trusting Vish or going against Dev.She needs to think and plan carefully and its not necessary that bcoz Bela was a Naagrani thus she was intuitive enough to know the truth.Bela did fight her own battles sometimes like against that chudail.Brinda has not even faced any serious threat so far.
