Hades had never lived on Olympus. He did not consider himself an Olympian god. The affairs of those who dwelt in the sky and looked at mortal life in a forward direction did not generally concern him any more than his affairs would have concerned them. They were different worlds with different rules connected only by a bunch of frayed threads. One or two which Hades often wished to sever. By calling on him, the girl had left their world and entered his realm. A realm where the Goddess of Marriage did not exist and could not be consulted. As the King of the Underworld, Hades didn't think he'd been doing anything wrong.
But as the Goddess of Marriage's brother, he'd made a terrible mistake.
“Perhaps I was acting a bit hastily,” Hades conceded. The quickest solution usually appealed the most to him. It also rarely turned out to be the best. That didn't seem like quite enough, so he reluctantly added “I should have brought this to you. Or at least considered how it might have effected your work.” He didn't really care how it effected the others she mentioned. To really taste success, one first had to taste disappointment. Disappointment was a large part of his enterprise.
“And you feel that if she were to meet him the...” he searched for the word for awhile, but gave up and gestured towards the girl waving his fingers clumsily around her current theatrics “...*that* would stop?”
“Maybe she just isn't the marrying kind.” Hades could understand that. He'd been extremely adamant about that himself for a very long time. Much longer than the girl had to live whether or not she went home with him that day.
