Oms doubt was cleared the day Gauri took that diff Kasam before God...
Gauri said
" hum Shankarji Ki Kasam khate hai hum Jo kar rahe hai sahi kar rahe hai Aur isme Hamari koi saazish Nahi hai..."
Omkaara knows that however Gauri is she will never lie before God... Om is very confident on this part of Gauri... That's why he after that doesn't insist on her taking any other Kasam...
Also wen Gauri is confessing to God about her pregnancy truth the second time it is Om only whose Shadow we see... Om has heard Everthing and he's actually waiting to see why Gauri is doing all this...
Om somewhere knows she's not lying for any personal gains ...
So he's quite and playing along with her Pregnancy lie just to see where all this is leading to ...
He hugged her yesterday as he knows she is feeling guilty for this lie ...
In short our Old Om is back who thinks intelligently and wisely ...
And I feel Omkaara Definatly knows the truth ...
Note... This is my prediction ... Let's see wat happens ...
