My gut feeling is that Raashi is playing a game with Bani. Her dad is after Jai Walia's property, Roshini is ticked off at Jai for ditching her, and Raashi though she didn't show it openly, but I am sure was very hurt when Saahil left her for Rano.
I bet the whole family is plotting against Jai and Bani, and Ranveer became the perfect bait.
Hoping our Khabri (aka Mr. Ram Kapoor) will give us some hints.
