Abhay was one of the lead since beginning. But ever since Abhay 2.0 was born, he matured so much. And specially after nikhil's entery he is reduced to a side character. He is hardly given more than 5 min screen timing. I wish they had shown more of D and A as friends.
The character arcs of all the junior residents has been great one. Everyone evolved in ways they never even thought of.
