Percy was hanging out at Annabeth's place with Leo, Jason, and Piper. (Leo had created a teleportation device between the two camps, Percy's house, Piper's house, and Annabeth's house for the five and was working on more). They all hung out on the couch as Leo and Percy kept making Bobby and Matthew's lego men have many mini fire/water fights when the twins were at school. Piper was laughing at her 'brother' and her best friend's silliness together, Jason was sighing while hiding a grin, and Annabeth had her head buried in her hands as she pondered on her stupid life choices.
"Die, fire scum!" Percy yelled as he sent a small blast of water at three of the yellow men.
"¡Muere, respira agua!"
"Die, water breather!"
"Te juro que voy a ganarte, Leo Valdez, el agua se usa para apagar el fuego, ¿sabes?"
"I swear I am going to win you, Leo Valdez, water is used to put out fire, you know!"
Annabeth slowly lifted her face out of her hands, Piper's jaw dropped, and Jason yelped out of surprise. Percy and Leo's heads turned when they realised their audience went quiet.
"What?" Leo asked innocently.
"What? WHAT?! DID YOU NOT JUST HEAR PERCY SPEAK IN SPANISH?!"
"Did they not know you were bilingual?" Leo asked Percy in surprise.
"No, they didn't know I was trilingual."
"TRILINGUAL?!" Jason yelled.
"Yeah, I know Greek too dude, jeez. Wait, I kinda know Latin, I'm quadlingual."
"Quadrilingual, you mean?" Piper helped.
"When did you learn Spanish?!"
"When I was four..."
Annabeth just stood up and walked out of the room, Percy's face was red, Jason's mouth hung open in surprise, and Piper and Leo just laughed at her 'brother'.
Nico burst through the door at the odd scene. "What did I miss?"
Okay so I have this headcanon that Piper and Percy are so close they consider themselves brother and sister. So yeet. I'm out. Also yes, I'm just posting all my stupid fanfics of PJO. :D
