my doubt - shivaay knows already

Call me crazy people but i think shivaay already knows about anika's orphanage secret and surname issue. What pinky asked sahil was actually normal questions if we don't know that anika is not his own sister. I mean its a normal question for elders to ask a new child what is his parents ' name, sister's full name and her birthday right? But the way sso reacted, when sahil was questioned and the way he broke his phone is giving me vibes that he already knows something. something atleast vaguely. Remember he made anika's lawyer to run off with the money used for power of attorney of sahil and his home.

I don't know about initial episodes. In some other discussion someone told he does not know what was the lawyer for. So no idea.

But he has time and again bashed her for lack of NKK. He knows anika does not have surname. Uski shaadi aise huyi phir bhi koi aaya nahi and no call nothing. She has told sahil ke ilawa koi nahi. Orphan news naya hosakta hai if he did not about what lawyer was for.
