I get what you're saying about GDBatman only dealing with Dick as Batman, but you've seen the stuff where he's trying to impress Dick with his stuff, right? He's consistently presented as less socially and emotionally adept than DickGraysonAge12. In my opinion.
I think that's true to some degree of the normal Batman, too
Agreed. I think it's because of his trauma and that what Miller did with that emotional age thing is just carry it farther.
