Yes he was embarrassed at her drunken antics, but he also knew she was not to blame because she would never drink intentionally.
The way Adiya had her back was so so admirable, he'll never leave her side. I mean to make his point clear to his mother he even doubted her- his POVs are always spot on. Papa Hooda like facts so he showed the drink- proven alcohol was mixed in her juice.
Aditya Hooda should've been a detective! He said he wasn't defending his Zoya but in his heart he knew someone stitched her up! He will find out soon enough Zoya's behaviour changing and all due to blackmails. He will probably get very angry at that point but he'll understand.
If i'm honest this track needs ending as all spoilers keep pointing towards a "will they wont they last for AdiYa!
All I know is, they didn't get AdiYa together to split them up, TRPs will be 0! They will face adversity together so long as AdiYa don't get MUs in their marriage.
So to the blackmailer, come out and show face, you have the whole BP fandom waiting to capture you before you get to our ADIYA!!
