Hi Ishana,
I would like to slightly differ from the common opinion about Papa Hooda.
I don't think he is changing colors or being opportunist. He has been always like this only is what I feel. Remember during initial episodes how he was irritated with Aditya's doings and only addressed Aditya to Anjana as her son.
The fact is he is first Justice Hooda, Papa Hooda is only second. He is a truly professional lawyer where facts matters the most than relations and emotional bonds, where as Aditya is different and trust his heart more.
So if it was Adi in place of Zoya, he would have reacted the same way, that means even if Zoya was his own daughter he would have taken the same stand. Just like how he calls Adi, Anjana's son, when he does something wrong, or something that affects Hooda's reputation, today he called Zoya Aditya's wife, whom he had acknowledged as his daughter just that morning, whom he had addressed only as bachcha since then.
But then when Adi presented the facts to Justice Hooda he agreed with him and looked convinced.
Now hope that Papa Hooda will be back.
He is like this only, even to himself, else he might not be here in this house now.
So I conclude that Papa Hooda and Justice Hooda/Harshwardhan Hooda are different personalities, and fortunately or unfortunately the latter is more prominent.
This is just my opinion. I might be proved wrong later. But at present this is what I think.
Thank you for reading😳
