Specifically, this moment (Civil War, Front Line #2) when he revealed his identity to the press and started to take questions.
What makes this puzzling is that we see Norman get furious for a few panels (as do others like JJJ) but there's no follow-up in this issue (or in the series) that explains why he said this (as far as I can tell!)
Trying to dig through multiple issues of ASM and the canon in general to figure out what arrangement or rules did Norman think he had with Peter back when their conflict was more frequent?
I doubt the former Green Goblin meant "super-powered costumed folk don't ever reveal their secret identity" (his was known far and wide at this time, anyhow).
So was there some moment during their bitter history together where Norman assumed some sort of pact or arrangement?
