Headcannon that when Jason was still Robin and in teenage rebellion phases, Bruce bought him a studio with blank walls like canvases and let him do whatever. He'd buy Jason Spraypaints and supplies for his birthdays or just whenever he needed them. After Jason came back from the dead, the studio became his "HQ". Though he didn't like Batman, he had to admit that he did one good thing in his childhood.
