Zeus listened, as was the appropriate course, and not only filed away the information for future use but tried to look for inconsistencies anywhere. He couldn't come across any at the moment so was going to, at least for now, take everything Hera laid before him at face value. Much like the first course of food.
He outlaid the things that had taken his time: problems on the ground level of Greece -which she'd be aware, and his discussions with Athena and a few others to nudge it into a less... vitriolic area if possible. There was no chance he was allowing their precious Greece to become the world's laughing stock. Not when the Middle East could still hold so much blame.
“There are peculiarities I need to investigate as well, in different manners. The granddaughter I've yet to speak to, for example, but has returned and yet,” Zeus looked over at Hera, “is spending far too little time on Olympus.” The look was a question if she had more information. Not that he had much favor for Harmonia, but... there was hope that she would yield more potential than some of her siblings had. Which would have been more promising had she not exiled herself after Cadmus passed on.
There was no way to address that if she did not come see him and Zeus did not think summoning her would have the desired result given their last encounter was full of insolence and tears, on her part.
He waited until the servants were out of earshot and in a lower voice said, “I'm not sure how noticeable it is to anyone else because there are only subtle behavioral changes but... something has had Kratos upset for the last several months and I do not think I need to state how important it is that we root out the cause of that and rectify it.” The last thing he wanted was for it to be something he could have fixed and didn't... and have Styx at his throat.
