Waaaaaay back at practically the beginning of this series, Wonder Woman (Spoiler) defeated Hades by staging a family intervention on the shores of the river Styx and teaching him to love himself (end spoiler). I love that even when faced with the most horrible crap imaginable, Azzarello keeps Wonder Woman as Wonder Woman. In anyone else's hands, the cannibalism and body horror that the Firstborn has unleashed would be kinda worrying, but that's not the case here so far.
And with the events of this issue, next issue would be a perfect time to spend a couple pages montage'ing the Amazons' past a bit and maybe putting this whole thing to bed once & for all.
