Hello! This is a quick introduction to the Mortal AU I'm writing now, but I hope you enjoy it. Before anyone says anything! The only ThaliaXLuke is friendship. Absolutely no Thaluke! I do not own PJO/HOO, that is Rick Troll Riordan's job.

"Percy!" Thalia called. "Percy! Slow down!"

Luke laughed at Thalia as she chased the four-year-old around the apartment. "C'mon, Thals! Cut the kid some slack. He's just having fun."

Thalia glared at Luke, "Not helping. You were the one that gave him all that ice cream in the first place."

"The boy turned four a week ago," Luke grinned. Thalia glared at him and Luke through his hands into the air, "K, k, I'll help you." He got up from the couch. "By the way, since when are you so strict on rules?"

"I don't want my cousin falling through a window, Castellan," the nine-year-old girl stated.

Luke laughed. "Okay, that is true. Hey Percy! Wanna go play some video games?"

"Video games?" Thalia asked. Luke shrugged.

Percy stopped and thought about it. He made his decision in a split second, "Okay!" He ran over and Luke caught him before he could go too far.

"And that Thals is how you catch a Percy," Luke grinned smugly. Thalia slapped his shoulder and Percy started giggling. Thalia ruffled Percy's hair and went to the TV.

"I suppose you can play video games," Thalia said as she turned on the console. "Might as well keep him occupied."

Luke grabbed the controllers and sat down with Percy on the couch. "Thals! There's another one y'know." She crossed her arms, thinking before she shrugged and took the third one. They sat there for the next fifteen minutes playing Super Mario, Percy talking energetically about his day before they came. Thalia seemed to be getting a headache ten minutes in.

Finally, Sally came in with the groceries and Thalia jumped up to help. "Let me help you with that!" As soon as she got all the groceries from Sally, Percy jumped up and hugged his mom. "Hi, Mommy!"

"Hello sweetie," Sally said, hugging him back. "Been having fun with Luke and Thalia?"

Percy nodded, "Uh-huh! First Luke showed me his uniform from his new school, then he Thalia got me an ice cream, then Luke told me a ghost story! Did you know you can get those at day?" Sally laughed and nodded. "Then Luke got me more ice cream and Thalia scolded him! But then she played video games with us."

Sally looked at Luke strictly, "You got my son on a sugar rush?" Luke shrugged and Sally picked Percy up. "We talk more in your room, okay?"

"Awww," Percy pouted. "I don't wanna got to bed now."

Sally laughed, "You're gonna need some rest Perce. C'mon." The two walked off to Percy's room and Thalia fell down next to Luke.

"I'm I gonna play alone, or?" Luke asked.

Thalia crossed her arms. "I don't know Luke. Should I punish you for getting Percy hyper?"

"Thalia!" Luke moaned.

The girl rolled her eyes and took the second controller, "Fine. I'll play with you." Luke grinned and Thalia whispered, "Childish."

Whatcha think? Review for more ice creams for Percy and all that! And thank for reading.
