Begin Again Book 1.

The Sorting/An Important Discovery

Harry Potter was content.

He had a real friend. Ron Weasley.

He walked with Ron, into the Great Hall, nervous about the Sorting. What if he didn't like his house?

Ron was in Gyffindor. So was that girl and the boy, Neville and Hermione.

"Potter, Harry."

His name was called and the hat wanted to put him in Slytherin, but Harry didn't want to. Harry asked to be put in Gryffindor. Yes!

"Isn't that all? Who else needs to be sorted?" Harry might have said that a bit too loudly, because three people still needed to be sorted turned around and scowled.

...Percy, Jason, and Nico...weren't they already sorted? Why were the scowling at him? Some friends

"Grace, Jason."

Without even touching his head, the Hat shouted, "Gryffindor!"

"Di Angelo, Nico."

Nico went up, but as soon as the hat was on his head, his poker face turned into one consorted in pain.

"Get out of my head!" Nico shouted.

He pulled the hat off as soon as it shouted, "Gryffindor!" But then to Nico, "I'm sorry, Kid." Did he imagine that?

Nico sat next to Jason, further down at the table. Harry saw he had a tear running down his face, looking like he had been slapped.

"Jackson, P-Perseus," Professor McGonagall faultered slightly.

Percy went to the front of the room, looking cool and confident, making some first and second year girls swoon.

As soon as the hat touched his head, his eyes went wide with panic, and a black, pained, scared expression, which Harry had never seen before.

"Get it off!" The new teacher had a caring look on his face. Did he know him?

"No!" Percy screamed. He then fell to the ground, screaming, grabbing his temples.

"GRYFF-"

The hall gasped. What was going on?

"SLYTH-"

Again, everyone gasped.

"HUFFL-"

Yet another gasp.

"RAVEN-"

Gasps all around the room.

"GRYFFINDOR!!!" The hat screamed, finally.

"Percy! Perseus Freaking Jackson, if you don't wake up, I will call Thalia Grace and have her whip your podex! Leo will burn you alive, Piper will murder you and Jason, Hazel will flip out, and don't forget Annabeth's signature move!"

"Wake up!" He muttered something in a different language, and Percy started sputtering.

"What the Hades just happened, Connor Stoll?"

Everyone gasped at how rude he was bring to a teacher.

"The hat looked into your memories."

What memories?

"What memories?"

"Probably dreams. Nightmares. Now, go sit at Gryffindor table."

Percy looked directly at Harry, hesitated, and sat down next to Nico and Jason.

Why were they being so weird?

...

Percy Jackson was freaking out. The hat showed him...things. A golden coffin. Darkness...Nyx? A face if a selling dirt lady. The face of...of...of...something called Tartarus...
