Not for the first time, Prometheus wondered why he came to Hades to complain. His friend always did this; poking holes in his rants and irritation and self-pity, forcing him to grudgingly concede that maybe Hades had a point about this or that. Hythlodaeus was far more agreeable and always humoured his complaints with a few sympathetic words and strategic nods. He never really offered any helpful advice, though, whereas Hades...

"I don't wanna go with the flow," he said petulantly, crossing his arms and pouting. He wasn't even bothering to hide his sulking, "And I don't wanna master my attunement with the Underworld. It's dumb and stupid and I hate it."

Yup, definitely sulking. It's like he regressed several decades into the melodramatic brat he sometimes decided to be.
