i agree,he is very perceptive observer.he notices everything and GC 's expressions as yash are awsome ..he need not have to talk to let the audience know what is going on in yash's mind..
And also this time in the last episode when in bed ,when yash hears the sound of bangels he does not seem to be very uncomfortable with it and he does not go into a flashback with his dead wife..he kind of gives an expression of acceptance of arti even when looking at arpitas picture..
thats some progress..
