You and some of the demi-gods at camp aka Percy, Annabeth , Grover, Jason, Piper, Leo, Hazel, Frank, Nico and Will were having a sleepover in the posiden cabin.

Hazel: "What are we doing tonight?"

Annabeth: She was setting up a snack box along with a cooler. "Me and Percy were thinking about sleeping in a tent outside of the cabin, away from all of the cabins. We already set up the tent."
