This is really confusing on one hand he told her indirectly and on the other hand he doesn't want her to reach the raaz
Cv’s wants to confuse the audience ,they have given ample proof that this is Vansh but at some point they have to confuse that he’s Vihaan too .
He’s leading her to the raaz and notice how Kabz is in the precap so maybe V is playing a bigger game .
