Had Pasiphae known to expect Hades at random times she wouldn't have been so surprised, and perhaps even tried to come pleasant even if inside she wanted to scream at him for even existing. But she didn't and so she had to adjust as quickly and as easily as she was capable. Which wasn't well.
That any of them expected respect from the others was beyond her. The things they had done to others simply because they were called Olympians was pure hilarity. They would have to step it up and show some respect to others before they got anything in return. It was truly sad there were still those around who worshiped them so diligently.
At first she was going to let him leave, because she had no desire to be around him. Even if Hades himself had done absolutely nothing to her, and in fact had made her own husband a Judge of the Underworld, it felt wrong to be near him. And then she frowned at herself because what if Minos came home moments later and heard what a snob she had been? She really didn't want Minos upset with her. "No," she said suddenly. "I'm sure he'll be home soon, you can come in and wait for him." Even if there was still resistance in her tone at least she was trying not to be a complete ass here. Although, she did eye the dog rather suspiciously. She wasn't certain if she was feeling two separate entities or if Hades really was giving off that much energy.
