Hello peeps. Sonu here.
When they were dancing and light went off. Jay left the stage and they showed someone going into the house. Later Jay entered from the gate when Vani were standing in a romantic pose. Nobody asked why he left the stage.
So it was definitely Jay who released the twin. And probably Veer's plan was only to kidnap Jai and marry Bani but Jay faked his death and got his brother killed.
Also, did Bani actually cause his death? My channel was behaving awkward at that moment. So did she cause the chandelier to fall or it fell on its own?
