I also loved the portrayal of the love triangle. This is probably my favourite episode so far. Maybe because I'm just here for Naagin , I don't have any bias so far. I equally enjoy VeerBani and JaiBani scenes. Both the couples have their share of charm. However today's Jai Bani scenes influenced the upcoming storyline. And Jai was in form today. I knew Mohit is apt for this role , he just had to adapt to the character , now that he has almost settled into the character Jai seems a lot more attractive. I enjoyed his scenes a lot , he owned the episode. JaiBani scenes were good too , I like the chemistry more with each episode.
Also about the bgm , maybe it's not Akeshwari's bgm but the bgm will be played whenever their past history is played out ?? I don't see any other reason of them playing it on Jai unless there's a twist in the story where Jai turns out to be Aakesh , there's some soul switching or smth. That's why the pandits are emphasizing on Bani searching for her true partner herself , to identify her soulmate.
