Witching hour headcannons
Ethan, who has been at camp for two summers about to join Luke's side, is now faced with a new kid who 1. Grieving the loss of his mom and 2. Ends up saddled with because Luke doesn't want to deal with him.
Percy, who is still blamed for the missing items. Not because of sibling rivalry, but because 1. Hades thinks Demeter is mad about Persephone again, 2. Zeus thinks Demeter is mad about him for Persephone and 3. Hades and Zeus think the other put Demeter up to it because of Persephone. So now Demeter kids are being faced with back lash, but all of them had been questioned.
Ethan has a power set that is a lot more shadow and ghost based. He can't summon skeletons, but he can reanimate or puppet existing ones.
Percy's power set is very ground and plant based. He's not so great at growing small amounts of plants as he is making them just go insane. Think big vines used to keep monsters in place or like root systems being used to make holes appear in the dirt. He will kill a plant if he's taking care of a singular one but give him a field and its plentiful harvest.
The prophecy still applies to Percy! In the modern public use of the word 'gods', it can mean all deities within a religion. Also the parallelism of Kronos being a Titan with significant connection to agriculture and land, and him having to face a child of Demeter.
Percy, who gets claimed during capture the flag and gets to have older siblings!
Percy gets sent on a quest and chooses his best friend and the one guy who might make a trip to the underworld easier.
Grover still gets the shoes because Percy is an earth person he doesn't want to fly even if he won't get shot from the sky.
Ethan and Percy are working together a bit quicker because Percy had already proved before he claimed that he didn't care about the godly parent thing.
Percy is showing up in the underworld and wondering if he can control plants made for the underworld.
Throne Room scene where he shows respect to his godly mother first, and this makes Zeus even more offended than before but pleases Demeter.
Percy and Ethan are having a soft, slow burn romance that takes the same amount of time to mean anything.
Ethan, who doesn't leave with Luke because he's seen the lengths Kronos went to during the quest and while Ethan still believes the horrible mistreatment needs to change he knows with first hand experienc this won't fix anything.
The Sea of Monsters happens so much more differently.
Ethan is picked for the quest with Clarisse because the Ship of Bone and Percy (fatal flaw still loyalty) is having none of it and wants to go as well.
Clarisse having to save the two of them from being household rodents. Just in general, this quest is more of a mess, but a lot of personal growth happens.
Luke is trying to turn Ethan to his side, but Ethan is having none of it.
