At times I feel Dude is more vulnerable (emotionally) than II.
He is mature no doubt but emotionally he is lot more anxious than II.
II shares everything with Akka. Even Amma at times. Dude doesn't share anything with anyone. Keeps all his insecurities to himself and suffers alone.
He might be angry lot more with Ranjan also coz he never expected anything even close to the scandal. Then he lost his mother.
Never went ahead to find the truth out of fear that doubt which he has might just get confirmed.
II coming in his life has changed lot many things. He is more around in MM now. He can see his old loving and caring father in what Ranjan does. Coming face to face with difficulties which his father faces. Might never forgive but may let go slowly now.
Strike might just prove catalyst in developing lost father-son relationship from Dude's end. Also having child of his own makes him see from Rajan's perspective. On having his own kids he might just feel more for his Dad.
