(A/N My family is doing a puzzle, so being me I stole one piece and now they're all freaking out.)

Percy

I knocked on the door.

"Come in." Hazel called.

I opened the door.

"Wow… Frank really went all out with the decorations." Annabeth said.

Hazel sat on the couch. "Yeah, he did."

Alex ran into the house and threw his arms around her. "Hi Hazel."

She laughed. "Hi Alex."

Nico was still waiting outside.

"Hazel," I said. "We have a bit of a surprise for you." I turned to the door. "Come in."

Hazel's eyes lit up. "Nico."

"Finally someone recognizes me!"

"Nico!"

"Hello Hazel."

"Nico di Angelo, where in Hades have you been?" She asked.

"I'm sorry," he said. "I shouldn't have run off like that."

"You could've been dead for gods' sake!"

"I missed you Hazel."

"I missed you too."

Frank popped his head out of the kitchen. "What's all the yelling about?"

Nico smiled at him. "Thank you."

"For what?" Frank was utterly confused.

"Taking care of my sister when I couldn't."

"Your sis… Nico?"

"Good to see you again, Frank."

"Nico!" Hazel said. "Where have you been?"

"Everywhere. Everywhere except home."

"Oh, Nico." She threw her arms around him.

I smiled at them. "Happy birthday Hazel."

"Is there cake?" Alex was jumping up and down. "I want cake."

"Alex!" Cassidy scolded her brother. "Be polite."

"Sorry."

"It's alright Cassidy." Hazel said.

"No, it isn't. That was downright rude."

"It's not your problem Cassidy." Annabeth said.

"Whatever." She flopped onto the couch.

Everyone except Nico sat down, as Frank brought out the cake.

"When's the last time you were at a birthday party, Nico?" Frank asked.

"Percy's fifteenth." He said.

"We need to fix that. Sit. Eat." Frank smiled.

There was a silence.

"So…" Cassidy finished her cake first. "You're a son of Hades, right? Shouldn't you hate dad?"

"Yeah." Nico smiled. "Me and your dad would get into the worst fights."

"You locked me up in Hades!"

"You almost strangled me!"

"I was in a cell because of you!"

"You jumped into the Lethe."

"Boys!" Annabeth yelled. "Not again."

"You jumped into the River Lethe?" Alex asked with wide eyes. "Why? How?"

"I… uh… was being attacked by a titan."

"You scared Thalia and I to death." Nico laughed. "He grabbed a huge titan and pulled him into the Lethe."

"Did it work?" Alex asked.

"Yeah." I gave a sad smile. "Poor Bob."

"Bob?" Cassidy asked. "Who's Bob?"

"Anyone want more cake?" Frank asked.

"Who's Bob?"

"I think that's a story for another day." Hazel said. "You two aren't old enough yet."

"What aren't you telling us?" Cassidy sounded betrayed. "I thought you told us everything."

"Cassidy…" I said.

"You told us everything from the beginning to the end, except one thing. Who shut the Doors of Death? No one was on the inside."

"They don't know?" Nico asked.

"Know what?"

"Tell her," Annabeth sighed.

"Your parents were on the inside. They fell in in Italy."

"I knew you weren't telling us everything!"

"Enough yelling," Hazel said.

"And she says she's more like Poseidon." Nico chuckled.

"I am! And if you don't want to tell me stuff, then I'll find someone who will!" She stormed out the front door.

"Cassidy!" I ran after her, but she was quicker.

Annabeth ran out. "Where is she?"

"I don't know. She ran off."

"Cassidy!"
