Percy and you had been friends since he first came to camp; you grew up together and were really close.
He wasn't always like this, but he's suddenly become quite protective of you. You had no idea why; your friends would constantly claim it was because he was starting to like you, but when you asked him about it, he just dismissed you.
Grover was gathering roses by the camp garden on a Tuesday afternoon when he got injured by a rose thorn.
Grover didn't want to go to the clinic because it was such a simple cut, so he came to you. Grover was seated on your bed in your cabin, and you were holding his hands while rubbing a betadine-soaked cotton bud on his injury.
Percy walked inside your cabin wanting to spend time with you. Instead, he spotted you with Grover. He became tremendously envious of the sight. Percy waited until you finished and Grover left.
“Couldn't he just go to the clinic?” He says, rolling his eyes. Percy, clearly envious, did not want any boy near you; including his best friend Grover.
