He sits in the manor in his room staring out of the window, upset and unhappy with his father because he didn't let him go out on patrol today and told Alfred to watch over him.
All because of that ONE time he tried to take on joker alone and got hurt..it was one time!
He isn't a kid and he isn't helpless either, he could've handled that annoying clown alone but his father treats him like a child. Well, he isn't a child! He was trained in the league and he is perfectly capable of beating that clown.
Now he is forced to stay inside while the others had the time of their lives?!..he was going to stay angry about this, and he definitely isn't going to listen and stay inside like he was asked to do..he tried to sneak out through the window.
Why should his father not even give him this freedom? He loves patrolling and his father can't take this from him because he made ONE mistake.
