What am I, Invisible?

by The Nightly Ninja

Percy wakes up one morning with a duplicate on his bed. oh. And he's invisible: the only way someone can see him is if they know that he's there, and since no one knows that he's gone, the odds of him finding someone to see and hear him are slim. fortunately, there IS one being that can see him. T for language and use of alcohol and tobacco.

1. Chapter 1

Percy Jackson woke up on the 4th of July, sprawled across the floor of cabin 4, with a doppelganger laying in his bed. While Percy never woke up quickly, he was on his feet in seconds, carefully observing the stranger. Well, not a stranger: it was him just… not… him. The son of Poseidon took a few deep breaths to calm himself. Despite the fact that he didn't succeed, something did calm him down: a sweet laugh that rang out just beyond his cabin door.

"Annabeth…" he mumbled with a smile, feeling his racing pulse instantly start to level out. If anyone could understand what was happening, it was Annabeth.

She opened the door and released another sweet laugh, this time saying the words that made the blissful smile melt into a look of horror; "Still asleep? Oh come on you seaweed brain, GET UP!" she moved right past Percy, pouncing on top of the duplicate, who moaned and mumbled one of Percy's unintelligible early morning complaints into the drool splattered pillow. Annabeth laughed again, starting to walk out again as Percy number 2 started to get up.

The original was frustrated now, grabbing at her foot as she left shouting, "What am I, INVISIBLE?" though when Annabeth turned around to look at him, it seemed that he was invisible; she looked right through him at the floor, even mumbling "A loose floorboard…?"

Percy's breathing hitched again as he stood up in front of her, almost whimpering, "Annabeth, can you see me? Annabeth, can you hear me? Please…Please… ANNABETH PLEASE!" when she gave no response, he trudged out of the cabin, to try to find someone who could see him.

At Cabin 1, he woke up Jason and Thalia, both of whom scowled in his direction before launching complaints at each other about waking the other.

He then went to the hades cabin, where Nico started cussing at the air like a sailor and hazel was distracted from his presence by Nico's profanities (she looked like she would have a heart-attack).

Percy went to Rachel's cave, to find the young oracle painting a shadowy figure in a black coat with a hood obscuring his face. When he tried to get her attention, she looked around calmly before returning to her painting.

On his way to the big house to try to get Chiron, he saw something that made him sick; his girlfriend playing their games with the faker. Annabeth really couldn't tell that there was something wrong.

Then again, Percy himself couldn't tell what was wrong with him either; the guy was a perfect replica of him, down to the specific way that he tripped on a certain patch of grass whenever they walked by it.

Sickened by the idea that the copy was so good, he continued on to the big house, where he found Grover and Chiron in the office, and Piper talking to Leo in the kitchen. Percy did everything he could to get their attention, but only Grover actually seemed to believe that there was someone else there, probably by his smell, though Chiron convinced him that there was no one else there. Leo had a minor panic attack and lit himself on fire while Piper yelled in charmspeak "show yourself!"

Having lost all hope, Percy started toward the exit of camp half-blood, asking if random people could see him as he went. Only when he stepped over the boundary did someone acknowledge him.

And Percy had a hunch that this man wasn't quite human.
