In this version of the show, Batgirl and Robin were the main Источник of sane humor, where as Бэтмен is his regular grim and gritty self, as opposite to Bruce Wayne, who plays a еще humorist character while keeping face. As this is, I do believe Бэтмен needs Batgirl and Robin so he knows how to have a good time while fighting crime, and the JLA knows he does have a softer side.
