actually the idea that Dick, the eldest, the only one who ever wore the cowl long term, the only one who raised a Robin on his own, is also the only one who can successfully, perfectly replicate that barked ROBIN! in Bruce's voice? the only one who can pull that exact tone from the depths of his soul, to the point where his voice is identical, so identical that old Robins like Jason are obeying before their minds even realize their bodies are moving? that Dick is the only one, has always been the only one, who can channel Bruce's voice? can channel Batman himself? I am going feral
Extra points if Dick didn't realize he was doing it because ever since his voice dropped when he was 13 that's the tone he's been using to yell at the Titans whenever they did something stupid. One day Tim does something during training, Dick snaps 'ROBIN' and Bruce drops his drink
