When Jagya fought with Gauri on surprice wedding day, their friends wtinessed only the initial part of drama.. after that G's father requested the guests to leave. So nobody heard Jagya talking about his life with Anandi. At that time I was wondering why did CVs show it like that.. All their freinds were invited for the wedding, but they didn't come to know about J's first marriage.. I think, the reason is, CVs plan to show J and G together(atleast for some more time) in the story line. If they have to live together in Mumbai as husband and wife, it is important to keep their friends and colleagues in darkness about Anandi and the illegality of J and G's first adult marriage.
There will be lot of drama, but at the end J will be back to G, whether they both like it or not!
