Harry Potter Crossover (Percy Jackson)

The Order in the House

Harry POV
           After the Dursleys left, I packed my bags and Percy and I took our stuff downstairs. We went back upstairs to wait. I guess I fell asleep because the next thing I knew was Percy shouting "Who the Hades is a death eater?"
          Oops. I forgot to tell the order about Percy.
I ran down the stairs to tell the Order. When I got down stairs, Ron and Hermione wrapped me in a tight hug.
"Harry! This imposter is pretending to be you!" Hermione exclaimed.
"Hey! I'm NOT an imposter! This is my actual look!" Percy insisted.
"Ron! Hermione! You guys are all here!" I shouted. I was very excited.
"Who else do you see?" A deep voice growled.
           Professor Moody.
"Half of the Order is in this house! Hi Bill, and Fleur, and Professor Moody and the rest of you guys!" I smiled. I mean, I've never met more than five of the Order before.
"Harry! Tell them I'm not an imposter!"
             Darn. I almost forgot about Percy.
"Oh yeah... uh guys? He actually is my cousin. I gave the him Truth Potion. He's also willing to help fight in the war." I explained quickly.
"How 'bout this. Percy and Harry do the Unbreakable Vow." Ron suggested.
"Sure." Said Percy.

I didn't really want to do this but I had no choice. Or else they might kill Percy! And so Percy and I held each other's hands as a red chain snaked around our wrists and Moody asked Percy the questions.
"Do you, Percy Jackson, agree to stay loyal to Harry Potter?"
"Yes."
"Do you, Percy Jackson, agree to fight for Harry Potter?"
"Yes."
"Do you, Percy Jackson, agree to assist Harry Potter in best of your abilities? As in fight your best protect your best, and company your best?"
"Yes."
Then, the chain disappeared and me and Percy both withdraws our wrist and starts to message it.
"So before we take this further, I'm a demigod, a race hidden among mortals just like you guys so please don't tell anyone else this besides this 'Order'." Percy warned. Hermione, as usual, was stubborn. "Prove it." She demanded. Percy controlled some water from the sink and shaped into a pegasus. For once, Hermione was speechless.

Moody just had to ruin the moment.
"Ok Harry. Give me one of your hair." Moody growls.
"What? I thought you were gonna apperate me!" I squeak.
"Change of plans." Moody growled again.
"No. I'm NOT putting anyone in danger." I felt angry. Suddenly, Hermione marched behind me and pulled a hair from my head and passed it to Moody.
There was a mix of 'ow!' and 'thank you Hermione".

Moody dropped my hair into the pre-prepared potion. It starts to be bubble and then stops. "Get me six cups."Moody demands. I ran to the kitchen and fetches him what he asked for.
Moody poured the liquid into the cups.
"I think it looks better than Crabbe and Goyle's." Ron joked. Everyone stared. "What?" Percy, Fleur, Ron, George, Fred, Hermione gulped down the murky liquid.
