It all started when everyone had gotten back from the quest of the Seven
Jason was in the lounge room of the Argo II where the Seven had decided to temporarily stay.
Thalia, Jason's supposed sister was snuggled up with a blanket on the couch with Percy Jackson watching America's Funniest Home Videos.
It made Jason absolutely fume!
He should be the one on the couch with Thalia, not that imposter Jackson.
While they were lying there, Nico, Annabeth and Grover walked in. Jason expected them to be shocked by Percy and Thalia's relationship but they just seemed excited about the show.
They all jumped on the couch and started munching away at the snacks.
They looked like one big happy family. It made Jason see red as he did the only thing that he could do.
He buried his feelings and walked away.
