So this just accord to me. Hephaestus becomes angry with his wife (Aphrodite) for cheating on him all the time, mostly with Ares. He even goes out of his way to embarrass them in front of the other gods with traps and TV shows. Then I remembered that Hephaestus has a lot of demigods children, maybe not as many as Aphrodite but still a reasonable amount. Those children didnt come out of the forges, what do you think?
