No reason to worry, the snake will shed soon.
They will clear after the blue stage and basically look normal, with clear eyes and skin.
Within a few days they will shed.
The reason for the change in temperament lies in the eyes. As you can see, the snake's eyes are now clear, meaning the snake's vision is back to normal. When the snake is in blue and the eyes are clouded over their vision is comprised and they feel insecure and in turn become defensive. Since the eyes have cleared and vision has returned to normal the snake isn't nearly as defensive.
