Alright so it's official people need to make more fanfictons of Percy coming home to Paul and Sally and surprising them. Anyway all rights go to Rick Riordan.
Percy
It was the day after the war was over and they were on their way back to camp. Percy was laying down on his bed just letting his mind wonder when he came across that never happened before, he had to write an essay for Paul's English class. Of course getting kidnapped by crazy goddess and well taking down Mother Nature had put a dent in his schedule so naturally he couldn't get it done. But he had nothing better to do so he was going to write that essay with only an hour left and he would hand it in to. So he went to work he started writing so fast that he hand started to cramp and he was even using Riptide, Paul better like this he thought.
Time Lap
He had finished that essay in record time he even had time on the ride over to his school to spell check it. Argus had taken the camp van to drive him over but before he left he took a look in the mirror to see how he looked. He had cut and bruises all over him and his orange shirt was all torn as well as his pants and his eyes looked a little haunted but all in all he still had the same smirk on his face. As he opened the doors to the school with the two page essay in hand he noticed that the hallways were empty and he guessed that class was in session. He finally found Paul's room and opened it without any knock or anything and interrupting Paul's speech "So class this week we are going to be discussing Lord of Flies so—," He was cut off by looking at Percy and the students gasp. Percy walked over to his desk and laid down the essay and said "Sorry this is a little late but um…well…I got a little side tracked."
"Percy,"
"Yeah Paul?"
"Please tell me that you are here because you won."
"Why else would I be here?" Paul ran up and gave his step son the biggest hug a man could give his son Paul had begun to develop tears in his eyes and the same for Percy. Percy let go of the hug and walked to the back of classroom and sat down at an empty desk all bruised and cut up gesturing for Paul to continue.
