You were Zeus's kid well older than Ares at the time anyways no surprise Zeus got hera pregnant again who would've guessed anyways you were still a child so you didn't completely understand just that your getting a sibling

As your mother sat on the couch reading, you came up and tried to climb into her lap and looked up at her and tilted your head, and she picked you up and sat you down as you asked a random question

She looked at you and shaked her head

Hera: "Cannibalism isn't hereditary sweetheart" She said softly
