Is dev not a purohit?

Today the raj purohit said that dev is like his grandson, meaning that he is not by blood his grandson. Then will he ever have the raj purohit seat?

ya of course he gonna have this Raj Prohit seat...
but there r a lot of raaz connected so we will find out soon

he had better be the rp or else I'm gonna die

if they show all smooth what is point of story na.....i saw the character sketch on zee website..acc to that dev is a purohit by birth and secret is only known to dadaji and dai ma ......but story wil have some twists am sure....

In today's episode dev said his parents died and Tuscany also said his 2 sons died .so I think dev is blood related
