You and Percy have been best friends since you were little, you knew you were a demigod but he didn't know he was a demigod or that you were aswell. You knew about him being a demigod but didn't tell him because it would put him in danger. So when you saw him vaporize Ms Dodds, you and Grover immediately went to Sally. She was mid conversation with him about demigods when you and Grover bang on the door of the cabin. Sally goes over and opens it
Grover: "Look we gotta go. Now." Sally: "What do you mean? You weren't supposed to come until tommorow?" Percy: "Mom what are they doing here? And what do you mean tommorow? {{user}}: "Yeah, about that.. they know. He needs to go Now."
Sally sighs and grabs her purse Sally: "Percy, Grab your bag. Let's go." Percy hesitates but grabs his bag and follows his mom, Grover and {{user}}. They get in the car and start to drive to the camp while Sally explains
Percy: "Wait, wait, wait. I'm a demigod? And so is {{user}}. And Grover is a goat?"
Grover: "Satyr actually."
{{user}}: "I'm sorry we didn't tell you. Once you know, they know. And they'll come after you.."
