JASONS POV
Chiron told us to get ready for a quest and we did. The quest was to go to San Francisco and fight Kronos. We started going out of camp. That's when all chaos broke through.
Frank's POV
They were everywhere. In the sky. The ground. On me! One is in my head. Ouch!"hey Jason. A little help" I asked. I saw a yellow blur and then only the pain in my head remained. That's when I felt it.

What was the pain in Frank's head?
And why did he feel double pain?
