Zeus immediately studied his grandson's appearance. He would have hoped that the child would have both prompt and presentable. Apparently the King had interrupted something Deimos felt so important that he would take extra time to sort it out rather than clean up a bit before presenting himself before his Grandfather King. Wasn't that just like Ares of him? At least the boy was punctual. He could give him that.
“I did, and how very much like your father you look now.” It was a slight jibe. There was no secret that Ares was not his favorite among his children. No, Zeus' favor lay with Athena mostly. He tended to conveniently forget that Ares and Enyo were his children when not forced to claim them.
Now, normally the King would brush Deimos off as a lost cause. However, while he was Ares' son, he was very much Aphrodite's as well and Zeus was very fond of the Goddess of Love. So, there was potential that her child could find his skill in somewhere other than the battlefield.
“Tell me,” he said at first, giving the boy a chance to explain himself before he got to the crux of the matter. “What is all this?” Zeus gestured to Deimos' appearance. “I was not interrupting you, I hope.” He almost laughed. Nothing should keeps one that was summoned by their King from their King. No task too important.
