Finally, you found him!

Percy was with his mom. A hurricane had started. She welcomed you in.

They were staying at Montauk, on the beach. Waves were crashing against the shore violently, and you weren't sure if it was the gods' fault or not. Sally Jackson was trying to explain to Percy what the hell was going on, but it was time to go.

The three of you hopped into the car, and Percy looked equally as scared and confused.

Just wait until he learns what Camp Half-Blood is.
