It was breakfast when Annabeth noticed. She noticed the difference in Percy.
He was sluggish, pale, and picking at his food. He looked at his plate disgustingly as if the food was going to make him sick. Annabeth had figured it was because it was early (Percy never was a morning person.) and decided it would be better if she didn't bring it up.
Knowing Percy, he'd probably say he was sick just to get out of his daily activities.
However, Annabeth realized she, surprisingly enough, was…wrong. Of any name that she had ever been called, this DEFINETLEY was her least favorite. Anyway, she had come to this shocking revelation when it came time for Percy to teach his class to the Athena cabin. Percy and Annabeth had been thrilled when they found out that they had more than their free time together.
When Annabeth got there, she realized Percy hadn't been seen since breakfast. After Percy had gone missing for eight months, Annabeth had panicked when she had heard this. She got up and ran to his cabin. More like sprinted. She opened the door and immediately saw Percy.
He was curled up in a ball in the middle of the floor, unconscious. A thin stream of blood was flowing from the corner of his mouth. Annabeth screamed.
People flooded in through the door. Eventually, Chiron appeared next to her in the cramped cabin. He noticed Percy's limp form. He helped Annabeth up and picked Percy up and together, they headed off to the infirmary. When they got there, Percy was given special care while Annabeth waited outside in another room.
After what felt like forever, Chiron came out and said one word that made Annabeth want to cry.
Poison.
