Percy Jackson Teaches at Hogwarts (Percy Jackson and Harry Potter crossover)

A strange teacher

Harry POV

"Harry dear, your going to miss the train!" Mrs. Weasley yelled up to me. I was staying in the burrow, because everywhere else felt lonely.
I was retaking my 7th year because, well, we didn't get much done last year.
I grabbed my stuff, and ran with Ron and Hermione downstairs to the car. I was so excited, the whole way to the train was a blur.
We found an empty compartment and sat down.
"Who do you think the new teachers will be?" Hermione asked, "I hope they teach us something we don't already know."
We discussed the different options on the way, excited for the new year.
"What could they teach us in DADA anyway? I mean, we DEFEATED the dark arts." I point out. "We just defeated the most evil wizard ever, I really doubt something else would happen in our life time. We deserve a break.
"Do you think their ghosts will be here?" Ginny whispers.
We all sadden by the reminder of the loss of our friends.
"I hope so." Hermione says quietly.
One of the other students came by to remind us to change into our robes. We quickly go and change, finishing right as we arrived. As we were going into the castle, I noticed a flash of light on the side of it. I really hoped it was just a teacher getting their lessons ready.

Percy POV

We flashed over to the school and Hecate made sure we were on the side of it so no students noticed us. I figured someone might have, but I really needed to get going.
I raced in to the Great Hall and sat down before the students got in. The other teachers had already been informed of the situation, so they weren't confused.
The students came in. A few of the students looked over at me, confused for a moment before sitting down. The oldest students looked a year older than my immortal age, but I was told to expect that. The sorting ceremony was kind of boring, so I didn't really care or pay attention. I clapped when the students did, but other than that, I just stared at the ceiling, looking at the constellation of Zoë.

Harry POV

When we entered the hall, I looked to who was sitting in the DADA seat. He was younger than me! What could he teach me that I didn't already know?
Then, during the sorting, he was just starting at the celing the whole time! He didn't even care! Headmistress McGonagle went up to make her speech.
"Welcome students..." I didn't hear what she was saying, because I was trying to figure out the new teacher. "...please welcome our new DADA teacher, Professor Jackson!"
He stood up, waved then made his own announcement, "Hello, yes I am Professor Jackson, but please, call me Percy, and thank you. I hope to teach you all something new this year. And by the way, don't make me mad, because I can wipe this continent off the face of the Earth in two seconds." And he sat down, everybody else was too stunned to speak, "And by the way," He said, "I will hold a support group for all of you who have PTSD. The first meeting will be in two weeks. All students will be excused from curfew as long as they are going to the meeting. Bring something or someone that helps you, and wear comfortable cloths, we might go overtime." And then went started eating.
