I meet the smartest girl

The leading girl was around my age, she had bright blonde hair and startlingly grey eyes that looked like a storm, I know who her parent was straight away. She walked up to us.

"Sean." She said with a nod.

"Olivia." Sean said back. The girl turned to me.

"So you're the newbie huh? Well I'm Olivia and you are?" she asked.

"Aydan. You're a daughter of Athena aren't you?" I asked. Olivia looked at me surprised.

"How did you know?" she asked staring at me. Suddenly I was nervous and I knew why her stare was making me nervous.

"All the children of Athena have blonde hair and grey eyes. Don't they?"

"Very good, yes we all have those traits. Can you tell who the parents are for my companions?" she asked motioning to the two other demigods behind her. I turned to one of them a tall boy; he was well built, looked very strong… like he worked in a forge all day. I pointed to him and said "Hephaestus?" he looked at me and nodded,
"my names Bailey and this is my half brother Max, we have the same mother but not the same father, so who's his father?" Max smiled, I could tell he thought I would never guess who his father was. I looked at him he was smaller than his brother, and looked less strong, his eyes held a darkness in them that reminded me of death, my mind froze and I just stared. Finally I said "Hades"
Max's smile fell into shock. "How did you guess?" he asked.
"Your eyes. They are filled with darkness and remind me of death."
he laughed "well that's a new one. I gotta say I've never heard that before, your not as bad as I thought you were gonna be kid."
I looked at him. "Kid? How old are you?"
"10 turning 11 soon." He said
"then don't call me kid, I'm older than you. Kid"
Max glared at me, "I take back what I said you're just as bad as I thought you would be."
at that point Sean stepped in. "ok guys break it up we don't want any fights at least not until we get back to camp, ok?" we all nodded. "Good lets go, Olivia how did you get here?"
"Car how else?" she looked at Sean like he was an idiot. Sean looked confused.
"Who's car?" he asked.
"My mum's idiot, we didn't steal anything. Ok?" Sean nodded
"ok then can she give you a lift back?" he asked
"yes but wait your not gonna come with?" Olivia asked suspiciously.
"No, I was sent here to look for half-bloods I'm gonna continue to look, you can take Aydan back to camp and show him around."
"Ok then cya later on tonight, loser" Olivia said as she started walking away.
"I beat you" Sean mumbled.
"I heard that." Olivia called over her shoulder "come on, Aydan follow me."
I glanced at Sean and he smiled at me, "she can be ok sometimes, just don't annoy her." He said and then walked of, back to class. I turned and started following Olivia, Bailey and Max.
