Does anyone know why the campers are bothering to make a boat? I mean, for the trip to Greece I understand, but couldn't they just...(read background info.)

First off: they will probably pick up a few Roman campers on their way to Greece (and probably Rome too :/) It's safer to keep 2 campers at the wrong place then bring a bunch of Romans to the Greek spot, and as soon as they meet they need to start hanging around each other so they can't stay seperate until the solstice because that spells out disaster for a few reason.

They also need a reason for the Greeks to trust Romans. Not everybody likes Jason, but if Percy were to stay safe, that would make Greece trust Rome more, and vice-versa.

Lastly, somebody Greek and somebody Roman need to know first hand about the other culture. Keeping a camper to the other side will soften up the clash. Percy being tolerant of this 或者 Jason of that will help Annabeth, Leo, Piper, Reyna, Hazel, Bobby and whoever else be.

But I wish they'd just get him back man!!!! Can Poseidon not help out? Can they not summon the cyclops? I am SURE Poseidon would be cool with that!

Anyways that's that.

They can't trust the Earth. Gaea is against them, they need to go over sea 或者 on the air. Imagine trying to travel all the way back to Camp Ceasar 沙拉 on foot while Gaea is throwing all of her forces against you... not going to work. And then they have to get all the way back to Camp Half Blood. Doesn't make much sense, does it? Percy has to get accquainted with the Romans, too. The two camps need the 下一个 6 months to understand the ones sent to the opposite camps and learn to trust them. That's why they have to wait.

Well Leo want's a project and in order to get to greece in time then they have to leave immediately after they go to the roman camp

I know that's what I thought. I think some of them are going to leave and bring Percy and a few Romans back and go to Greece.

Cuz Percy needs to get their trust..

Either that 或者 they're mental...
