Hades heard her and looked up. It took him a second to figure out what in the Tartarean blazes his sister was doing in his temple. Hades nearly jabbed the girl with the staff immediately on principle, but refrained. She was making that face at him. He hated it when she made that face at him.
On the way over, he'd come up with a plan. First, the girl would die. Then Hades would take her soul with him back to the Underworld. Next he would hand her over to Minos and the others, and make himself scarce during her judgment. From what he'd seen of her so far, he thought she was probably an idiot. That created a bias on his part, and made it harder for him to be impartial. After she was judged by the others, Hades would finish up the paperwork on her, and put this all behind him. He'd already gotten started on it before he came. This was the plan. Hera was not a part of it.
There was absolutely no reason for her to intervene. She had her own temples. Hades was actually very proud of how feared and loved his eldest sister had become. There were a lot of Hera temples, and they were probably all bigger and shinier than this one and filled with even more sobbing foolish women who stabbed things in her honor. Women sobbing over their impending....Oh. The rest of the prayer. The part that Hades didn't particularly care about, because it didn't have anything to do with him and had more to do with....., well,...maybe there wasn't absolutely no reason.
Hades sighed, and pulled the scepter out of the princess's reach. “I suggest that you consider the choice you are making for a few moments more, while I conference with my eldest sister,” he told her. Clearly this was a matter that also fell into Hera's territory, and he had better hear what she had to say before he did anything. There was a very good chance that she cared more about the outcome of this situation than Hades did. Especially if this was one of the marriages that she had personally arranged.
He left the girl and met Hera. Being queen definitely suited her. She looked well, but irritated. Still, she was his favorite fiercest sister, and Hades wished they were meeting in more fortunate circumstances.
"She really wants to die. She won't stop asking, and she killed a cow without eating it and everything," Hades said when out of the princess's hearing distance. That was the debacle in a nut shell. It was a substantial cow. It made Hades feel like he owed something to the girl. And the peasant family that could have lived off of it for weeks.
