First thing first:
1) how did AD tell Jai to do it?
2) How did Jai tell the whole family, his sister,and the whole Gang?
Isn't there some "sharam" in the family that will stop u from discussing these things with your sister, friend's mom(dadi).
This family really is very modern. Dadi knew about "rano and Ranveer" the moment they were done, and now the whole family is discussing Jai and Pia.
Amazing. I hope the kids don't know :), or they were also listening to the discussion
