So! This page.

With Lordon on Earth, it’s something I’d have to touch on eventually. And I realized that, unless a reference slipped in I don’t recall, guns have never factored into the comic in any way before this. In my head, that was always a big part of Hereafter as a place: they’ve had war, and weapons, and violence, but not guns — those are strictly an Earth thing. And it’s been established that Lordon keeps a pretty… loose eye on things “down below”, so I liked the idea of him having no concept of the things (particularly automatic rifles).
