You know, I think you've actually managed to capture two perfect moments here. One, of course, is a defining image of Dick Grayson, but the other is the defining divide between the DCU and the DCAU. Same concept, same character; in the DCU it takes a whole page, and gets in deep and draws on years of important history and canon, while in the DCAU, it takes a panel and is all about things implied and streamlined and stripped down to the core.
