One plot idea could be that Valentino and Vox form an unexpected alliance to take over a new part of Hell. They might start by manipulating some of the lower - class demons to do their bidding. Another could be a story where they both have a falling out over a shared interest, like a powerful artifact in Hell, and then compete against each other in a series of challenges. A third idea is that they have to team up to face a common enemy, perhaps a new demon who is threatening their power and status in Hell.
