We all including myself are wondering how come Veer does not have any doubts on RV.
But trying to put myself in Veer's shoes.. Veer never got parental love, Digvijay loved him but could never stand against Rajeshwari's rudeness to Veer.
Veer has seen Rajeshwari doing wrong with him all his life, specially the last 2 times with Fake video and licence case, he knows she can go to lowest level to get what she wants.
Now, with RV coming, he has realised that he's not an orphan and also RV is the sweetest and most caring Dad in front of him. For him, anything going wrong, there is an obvious person who can do that, and he has more than enough reasons to believe that. It is difficult for anyone to fathom that both his parents in the name of his happiness want to take away the biggest happinessof his life. I think he deserves this much benefit of doubt. (I know I am getting soft on him, but I can't help it poor thing has got the worst set of parents)
