"Percy! Percy what happened! You look like you're about to faint!" Percy took a short breath of relief. Annabeth thought something was wrong with the stranger, or himself, who was clearly about to pass out.
"And who are you? I haven't seen you before!" she continued, now looking at the stranger; at Percy. Percy knew that Annabeth wouldn't believe him about what happened unless it came from Percy, so he made up a convincing, if not conceded lie.
"Percy here helped me get into camp safely. There were… um… basilisks, yeah basilisks near the river not to far from here. He pulled out Ri- uh, his sword and cut off the first one's head. Then he controlled the river to pick up the second and drowned it. He was very brave. Very."
"Than why is he about to faint?" she pointed out
"Um... mmm... exhaustion"
"Ok, next question. Who are you?" she asked calmly
Gotta think! Gotta think! Gotta think! "I am, um, Sebastian" Percy blurted out
"Sebastian?"
"Yes, Sebastian Xanthus" He confirmed. Percy hadn't told anybody this, not even Annabeth, but for the past month he had been having dreams about Sebastian Xanthus. Percy hadn't learned much about Sebastian from his dreams except for his name and that an unknown enemy had captured him. Sebastian told Percy specifically not to tell anyone about him and Percy had an urge to trust him.
"Sebastian Xanthus, huh, than you must be the son of a minor sea god" Annabeth said in a matter-of-fact tone
"Um actually I-" Percy was cut off by the sound of moaning
"Uhhhhhhhhhh" grumbled the stranger; fake Percy; Sebastian. This is way too much to take in thought the real Percy; stranger; Sebastian. Wait, what?
"Uhhhhhhhhhh" the grumbling sound came again from that guy, who was starting to slip off of Percy's shoulder.
"Oh gods," started Annabeth "I'm so sorry Percy!" Now Annabeth was helping that guy back up. "I almost forgot you were here! Come on, Sebastian, we better get him to the infirmary"
