(A/N: This part has been unpublished for months now, since I was busy with other books. Anyway, enjoy!)

PHINEAS' POV

After Isabella and I spent the next two days just having fun playing videogames, I saw something interesting on the news. Someone spotted a teenager wander into a forest, then suddenly just disappear. Police investigations led to no result that didn't involve the extraordinary. Of course, being a person who was branded the label of extraordinary, decided that Isabella and I should go there too. Maybe the disappearance was caused by an invisible rift or portal that leads to somewhere.

We arrived at the location, and saw nothing at first, but then we wore special glasses that are able to see through invisible barriers, and we saw something really awesome:

A place, something that seemed like a summer camp, hidden to the human eye, away from civilization. Isabella and I tried entering, but only I could. Since I wouldn't want to go inside and leave Isabella behind, we headed back to our room, and I decided to text Ferb for clues on how she could enter the barrier.

FERB'S POV

(A/N: Bold-Italicized: Ferb, Italicized: Phineas)

Ferb, hey, Isabella and I need your help.

Okay, what for?

There's this barrier we found. Isabella couldn't enter it, though.

What is it made of?

It seems to be made out of some kind of.....unidentified substance.

Magic?

Yeah, possibly...probably.

Dude, both of us know that science can't be used to explain magic.

Wait. There's something else. I think the barrier's source of power was a large tree. Maybe the barrier could be made of something organic too. Ferb, send me the blueprints for our second Beak suit.

The one with the ability to phase through anything organic?

Yeah, that one.

On it.

I took a photo of the blueprints, and sent it to Phineas.

ISABELLA'S POV

I waited (and helped) while Phineas was busy with making....whatever he was making. When he was done, he gave it to me and told me what it was. Once I put on the suit, Phineas and I went back to the barrier, and we entered.

Everything was a bit blurry for a second, but once it cleared up, I was filled with wonder.

There were lots of people in orange T-shirts, sword fighting, and running obstacle courses. It reminded me of Fireside Girl training. Then, a boy about the same age as Phineas and I noticed us, and approached slowly. The boy with black hair, sea-green eyes and a pen was with a blonde-haired girl with gray eyes holding a blue Yankees cap. I took the opportunity to ask "Whatchadooin?"

The blonde-haired girl asked "Uh, how did you two get here?"

Phineas explained everything, and I saw that the girl was clearly interested. I wasn't supposed to get jealous but I sorta did.

"Phineas, should we leave?" I asked him, just so that girl would leave him. The girl must've read my mind when she explained "Relax, This guy's my boyfriend, his name is Percy." while pointing to the green eyed, black haired guy. "I'm Annabeth." she continued. Phineas already introduced us, so I stayed silent.

"Anyway, we're searching for one of our lost friends. He was lost in the Giant War, but we never found his body and he had the Physician's Cure with him, so he might still be alive. But, one of our members have been spotted by the media, and we're trying to stay undercover. We need your help, demigod."

"Demigod? What're you talking about?" I asked.

"Not you, just your boyfriend." Annabeth said.

"What?" said Phineas, confused.

"You haven't met one of your parents for a long time, you're unusually hyperactive, those stuff. That means you're related to a Greek god."

"No way. Those are just legends." said Phineas.

Then, Percy suddenly summoned water and controlled it. I was convinced. Phineas wasn't.

"You might have something hydrophobic hidden—"

"Who's hydra phone Nick?" Percy cut him off. Annabeth rolled her eyes.

Then, a red, glowing hammer appeared to suddenly float above Phineas' head. A centaur saw this and said,

"Welcome to Camp Half-Blood, son of Hephaestus. I'm Chiron, and that's all you need to know. Now, let me escort you to the video viewing room."

(A/N: This is just part 2 of the alternate ending for this story. It's also the sneak peek for the PJO and PnF crossover fanfic. The second chapter will explain what they'll do to Isabella since she isn't a demigod, and why Phineas couldn't see through the Mist. Of course, that's in a separate book.)
