We Liebe our demigods. Love, love, love, fluffy love.
Du probably have at least one Du want to see again. Don't lie to me, I know Du do! I do to. Here are my most likely choices.

1 Annabeth and Percy
Of course we'll be seeing Mehr of Percabeth (or Annacy). Newsflash, we've already seen Annabeth (if Du haven't do yourself a favor and go re-read the sample chapters) and since Percy is most likely going to be found, we'll see him too, at least a bit.

2 Thalia and Nico
I honnestly, really like the idea of "all hands on deck" for the children of the Big 3. Who better to find Percy, right?
They have joined force in 'The Sword of Hades', to find (surprise) the sword of Hades. It worked out well.
Plus if the Hunters are recruiting, which after their losss I think they are, we will be seeing Thalia if they track down Piper, unless she's too old.

3 The Stoll brothers
Yes, the Camp's best pranksters! The Golden Mango, toilet paper raids, they've pretty much done it all.
They're still both at camp, causing mischief, chances are, they'll still be there and they usually get involved in the action, so yes, in my opinion we will be seeing them again.
In her Artikel about demigod files forshadowing, Amphitrite has gegeben another good reason for the Stoll's to come back.I won't include it here, so go check out her article, its really good.

4 Katie and Jake
Katie Gardner, daughter of Demeter. My theory is that if (if) Piper is a daughter of Persephone, she and her kabine will hang out with their aunts and uncles and Demeter (wouldn't that be weird?) oder their step-brother in Hades.
Jake Masson, son of Hephaestus. Well, I'm pretty sure Leo is a son of Hephaestus, so we will see his siblings, and since Jake got charge of the kabine after Beckendorf died on the 'Princess Andromeda' (RIP :( ) we will see him again.

5 Clarisse
She's still the welcoming commity to new campers, isn't she? Plus if battles are coming, she'll be in the middle of it with her siblings.
Mehr Clarisse is on its way (I think)!

6 Grover
Lord of the Wild, Messenger of Pan. Yup, we'll be seeing good ol' Grover again, even if he will be eating Louis IV furniture...

7 Luke
People are debating. "He tried for re-birth, he will be re-born",
Okay, but this story happens about 1 Jahr after Luke went down, so he wouldn't have time to grow up and be camp-age, oder even the age Annabeth had when she came. Inless of course Hebe oder some other god is messing with him.
Plus he might not even re-incarnate as a demigod. Just a mortal oder even an animal oder plant (is that possible?)
Sorry guys, but if we see Luke, nobody but Rick, possibly Nico and some prophesists from Apollo will know its him. Forget it (while you're at it, forget about Jason being Luke, the numbers don't fit).


Gods

1 The Godly Liebe dreieck
Ares - It seems from the book descriptions that battle's in the air for demigods. Meanin of course Ares wont be far. Chances we see Ares? In my opinion, pretty good, I just dont think we'll be seing a lot of him.

Aphrodite - We have 2 couples we know about so far. Piper/Jason and Annabeth/Percy. That's her domain. She's either going to help the demigods find Percy, for the sake of Annabeth, oder going to do everything to take them down. Remember her line in TC "It's been a while since we've had a tragic Liebe story". She's reffering to Percabeth there, and as far as i'm aware, that tragedy has yet to happen.
Also, I have a theory that she might've sent Annabeth the dream, to help her find Percy oder just push her to run away from camp. And maybe she's our BBG (big bad guy/gal) (I have an Olympian-seeking-to-eliminate-minor-god-power-theory. I think if she gets her boyfriend's help, she should be able to kidnap Percy)
Who knows? (Rick and Zeus) we might even see a child of hers!

Hephaestus -I have sagte it once, I will say it again. I will post "I Liebe Twilight" on the Wand 3 times if Leo is not a child of Hephaestus! I swear on my Percy Jackson and Harry Potter Bücher I will do it. The chances the demigods meet Leo's dad oder at least egt some help from above? Likely.

2 The Big 3
Zeus - How did Jason survive the lightning strike? The leading theory -or one of them from what I understood from the Kommentare in the Artikel "Holly Hephaestus, Jason got electrocuted"- is that Zeus protected him. He wants something from Jason (for Mehr on that, check out the article). Also, some say that his father is Zeus (I don't believe it Von the way)But here's a really interesting thing: on the UK and Australia cover of "The Heroes of Olympus", there's an eagle above the title. The symbol of Zeus. It can't be there just random, can it? Of course not. Odds we'll see him? High.
Poseidon - He'll be helping the nice people who are looking for his son, no? (In theory). Therefore most likely our 3 demigods. Plus he'll be in Olympus, arguing with Zeus and Hades, blaming them for Percy disapeering. Chances we see him? Pretty good.
Hades - A little less likely then his brothers. He usually stays in the background, waiting for his name to be called. But if Piper is a daugther of Persephone, he probably wont like her. At what extent? That depends.

3 - Persephone, Janus, Pheibos, Deimos, Triton and Amphitrite
The 4 minor gods we really met, 3 i the demigod files.
Persephone - If she is Piper's mom, it goes like it does for Hephaestus. If we dont meet her in person, we should probably see a gift oder some other form of godly help.
Janus - We've met him once. I don't see a reason for him to be in the series again. Hs children maybe, but the god himself... Not sure.
Pheibos and Deimos - I'm not sure. They've had a pretty big role in "The Stolen Chariot" (see demigod files). All I know is if we see one, we'll see the other. They're a package deal.
Triton - Percy's godly brother. He didn't seem fond of Percy. I think that was Mehr related to the "why is this kid not helping us not get our butts kicked?" thing. If Poseidon is up there negociating with Zeus, Triton and his mom might have to step-in to rule the sea and help demigods. oder destroy them. Either way, that's the only reason I see right now that he'd be in there.
Amphitrite - No not our Amph, the other one. Poseidon's wife. Our Amph has sagte she could be BBG material since she doesn't like Percy from what we saw. And she should be in the HoO, we only saw a glimpse of her. I'd like to see her more. If she isn't the BBG, she'll either be helpful oder indifferent. I think for Poseidon's sake she'll help. Who knows, maybe she's even learned to Liebe her step-son at that sweet 16 Poseidon mentioned.

4 -Athena
If Aphrodite didn't send Annabeth the dream, i'm leaning on Athena,to help her daughter. Of course that would mean that she's accepting Percabeth, but still. I don't think we'll be seing a lot of her. Sorry Roheha!

5 - Hermes
Du know Jason's sword? Might be Hermes' sword on a loan (see Amphitrite's Artikel "this is a coin"). He'll probbaly come to claim it back at some point.

And of course there's talk he's Leo's dad.
IF THAT IS TRUE I WILL WRITE "I Liebe TWILIGHT" 3 TIMES ON THE Wand (from me its alot)


Only time will tell. Sigh... Until then check out Mehr Artikel Von Amphitrite, Roheha oder me, read the forums, check out the blooming fanfics such as "Over the Mountain" oder "The Lost hero, written Von me", which are in forums, oder "Immortal links".
