please don't over-analyze the raaz, because it kills the suspense, and now a lot of you are disappointed because the raaz is not as hyper as it should be, but all this predicting and guessing made it a chota raaz
but this i can tell you, the reason Jai didn't want to tell Bani is he already started to care for her, already in the beginning, he felt ashamed to be responsible of killing the mother of the person who was already in his heart, but he did not realise
the more he got fond of Bani (hoping she will love him back), the harder he tried to hide it from her, that's why i think it was the Jai-dude who wore the white gloves, just to scare her off
anyway, i noticed one particular thing also, Jai and Jigyasa shout equally loud at Bani's face on so many occasions, so they are truly bro and sis
I also don't think that Jai killed Bani's mama, but i think Roshni framed him to cover up for her brother and at the same time trying to get rid of her fiancee Jai, if he would go to jail she could pursue her career etc
THE RAAZ IS NOT IMPORTANT,
THEIR LOVE IS
MAYBE THE PROMO OF 7TH JULY MEANT THAT now Bani will finally find the love of her life ❤️ ❤️ and that will change her life, i hope so for her, in the end all that she has endured will fade away and she can finally go on her secret honeymoon 🤗 with her Jai-love and than she will say: my darling husband Jai, i have loved you from the beginning and he will stare at her ,take her in his arms and kiss her passionately while the sun goes down into the sea 😳 😳 😳
