SO FUNNY......... Can someone explain ...

I just don't seem to get something clearly abt the new characters in KTH:

Siddharth (K Street Pali Hill, Kasamh Se) will play Ahluwalia's brother-in-law;

Mrinal Deshraj will be Ahluwalia's ex-wife's sister.

If Shipra Arora ( Mrinal Deshraj ) is bauji's ex-wife's sister, doesn't that make him her jiyu or am I mistaken ??? And if that is the case , why the hack does she call him bauji , instead of jiyu 😕 😕. The same goes for Siddhart also; I fail to understand why these ppl keep calling buddha bauji 😆 😆
