Yeah, and I've heard that Bruce was originally thought of as vaguely 30 but I don't remember where.
Oh so that where the 8 came from, but then Bruce would need to be 18 at least when he started, so I don't think that's written in consideration with the other ages. I wonder if he and Devin Grayson also saw the birthday spanking issue and counted backwards to the publication date like me, and concluded it was 8.
I saw Silver Age Wally and he looks like a baby in a onesie ^^
