Aka Angel-Demon Baby Daddies and The Bad Stuff.
I left talking about Deblanc and Fiore till the very end for a few reasons – to give more people time to catch up (have you watched Preacher yet? HAVE YOU?) and because I love them so obviously, I saved the best for last. In the comics, Deblanc and Fiore are barely there cardboard standouts that exist to provide some more jokers for Jesse to beat up in his search for God. They come to Earth to look for Genesis, but give up fairly early on in favour of the pleasures of doing cocaine and masturbating. Oh, Garth Ennis, you wacky scamp.
Beware the spoilers for all of Season 1 below, as well as a trigger warning for discussions on suicide & racism.
