So, here is another one that I wonder if anyone noticed. So according to Alcyoneus, he must be revived first before any of the other giants rise. However, Otis and Ephialtes claim to have been helping Arachne capture demigods for centuries (Ephialtes even has the coins of past Athenian children). However, Alcyoneus has only been revived for about 30-40 years.
