Sorry it's pretty short. Things happened.
*General PoV*
Annabeth had given Piper and Leo a basic plan for keeping Luke from turning evil. According to Percy, Luke had nightmares from Kronos after the failing to kill him after the hellhound incident, so if he had dreamless sleep, Luke might think Kronos had discarded him after his purpose was over, and he might be reluctant to turn to the titan's side completely.
The first order of business was getting some sort of sleeping potion, and Leo was elected for the job because apparently Will trusted him and would be more likely to give it to him.
Leo approached him in the infirmary where he was healing a camper's broken wrist.
"...Keep the cast dry, and come back tomorrow." Will said to the camper.
She nodded, and raced out of the infirmary.
Will turned. "Hey Leo. What do you need?"
Leo went straight in. "Do you have something that can give me dreamless sleep?"
Will nodded. "Yeah, but why do you need it?"
Leo was fine with sharing his tragic past, especially after Jason and Piper had made sure that he knew his mother's death wasn't his fault, but he wasn't sure. The fire had started because of him. And if he had to tell Will, he would.
"My mother died in a fire, and capture the flag was the first time I had used my fire since then, and it brought back nightmares of it."
Will looked at him sadly before rummaging around the shelves. He pulled out a small bottle with green liquid sloshing around. "Three drops a few hours before you go to sleep and you should be fine."
"Thanks Will." Leo turned to leave.
"Come by sometime, okay? It gets lonely sometimes."
Leo nodded before leaving to start the next part of the plan.
