"Are you serious?"

A devious grin spread across Leo's face. "Dead serious."

"It's hard to tell if you are when you're smiling," I said.

Leo placed his feet on my desk and tilted backwards on his chair. "I am not smiling."

I rolled my eyes and smacked his legs playfully. Leo had just dared me to steal the diet Coke can from the desk of a snoozing Mr. D.

Mr. D was a teacher at our school, but I honestly had no idea what he supposedly taught here. In fact no one knew. I'd either see him patrolling the halls between classes and giving everyone who dared to walk even slightly fast the stink eye, or I'd catch him discreetly taking swigs from a flask in the teacher's lounge. But mostly I'd see him here in detention.

And I spent a lot of time in detention.

I was a regular here in room 2B, along with the Stoll brothers (they liked pranks), Clarisse LaRue (she liked bullying), and Clovis (he liked sleeping in class). Sometimes my half brother Percy would join me here, but I rather not get into the weirdness that went on between us. It gets… complicated.

Anyway, today in detention we had our regulars, myself included (I liked screwing with authority), and Leo Valdez. Leo was cool and funny, but I've never hung out with him besides in detention. He hung out with Percy and his friends; I hung out with the trouble makers. We swam in different circles, which really sucked because I kinda liked the dork. Too bad he was dating that girl, Whatshername.

"You're crazy," I told him. "The last kid who tried to steal Mr. D's diet Coke got decapitated. Twice!"

Leo scoffed. "Okay, that's obviously not true. How the heck do you get decapitated twice? What, did the kid have two heads? And wouldn't that technically be two kids?"

I waved off his questions. "It doesn't matter. I know you haven't been here long, Valdez, but you'll learn fast that it isn't wise to mess with Mr. D's diet Coke. I bet it's not even real diet Coke. Mr. D probably switched it out with happy juice or something."

Leo laughed and raised his hands in surrender. "Okay, okay. Make your excuses. I can understand if you're too scared to."

I narrowed my eyes at him. "Is that a challenge I hear?"

He raised an eyebrow at me, and my stupid stomach was invaded by stupid butterflies. My ability to say no was pretty much shot at this point.

I got up out of my chair and stalked over to Mr. D sleeping at his desk. I felt everyone's eyes on me as I took each step.

Mr. D slept upright in his chair and held a copy of Vineyard Style magazine against his plump stomach. His head was rolled back and I could see a trickle of drool in the corner of his mouth. Ew. The diet coke sat undisturbed on the desk.

I sighed and looked over my shoulders. Leo was grinning like a madman with two thumbs up in the air. Travis and Connor were trying to suppress laughter. Clarisse had her arms cross, waiting to see my next move. Clovis at least stopped snoring for the moment.

Well, no use changing my mind now.

Slowly—careful not to make a sound—I closed my hand around the cool silver can.

Mr. D's eyes snapped wide open. He grabbed my wrist.

And no. I did not squeak like a puppy.

"And what exactly do you think you're doing, Ms. Fawcett?" Mr. D asked me in a dangerously even voice.

My jumbled mess of an excuse was blocked out by the hysterical laughter of my detention mates. Leo laughed so hard that he fell out of his chair and hit the floor, but he didn't let that stop him. Clovis was woken up out of his dream, screaming the chorus to Michael Jackson's The Girl is Mine.

Needless to say that Mr. D gave me eight weeks worth of detention after that for what he called "an outrageous disregard for the Student Code of Conduct." I learned not to do the stupid things that Leo dared me to do after that.

…all right. Not really.

A/N: I've had this high school AU in my head for a while where Kai goes to detention a lot and hangs out with Leo. She's still a child a Poseidon and her mother's infidelity has led to discord in her family. She and Percy aren't really close. Hayden is maybe dead or maybe not. Kai and Nico are friends and Nico is out of the closet. Kai is almost killed in a car accident and loses a leg. Leo is dating Khione, but she's verbally abusive and unfaithful. Leo doesn't break up with her because he doesn't believe that he deserves better and thinks he should count himself lucky that any girl would want to be with him.

(Actually, if anyone knows of a Leo fic like that, please send me the link. If you write a Leo fic like that, please send me the link.)

Anyway, I haven't posted a story in a while and figured I should give you guys something. I've been writing, but I used the prompts for the :icondemibloods: 100 theme challenge on Deviantart and picked themes that were waaaaay in the future. I was dumb…
