ok so after observing veer's behaviour in the mehndi ceremony i feel it was all his game plan to marry meera and organising function to call bani to his house with her entire family including jay.. putting mehndi oh her hand with his name on it...dancing and flirting and doing all the rituals to get married to her..then he actually made another dupe of him so bani will kill that guy and he can blackmail her to marry him by kidnapping her entire family..i remember when veer/teer was outside of that temple where jay and bani was doing that funny salsa dance he clearly said meri sweetheart bani yahan kya ker rahi hai woh bhi is jay ke saath....it means it was veer...i feel veer already knows the truth about bani being an aadi naagin as well as how powerful she is...the only way he can get her is kidnapping her family and blackmailing her...i think he is very clever and it was all part of the plan...he was very happy and laughing the entire time as he knew that he is going to marry bani..
