Harry's POV:

When Ron and I came downstairs, we saw one of the new exchange students go to our back yard. Hermione was crying; meanwhile, the black-haired girl was talking. Ron asked Hermione what was wrong, and when she didn't reply, he attacked black-hair, assuming she did it. I think he went too far. Unluckily, Ron ended up on the floor with his arm behind his back. Hermione told us to stop and that Thalia (the girl) didn't do anything and then broke up with Ron and told us she was engaged to Draco. Both Thalia and the boy looked surprised.

"DRACO?" Ron askes.

"Yes," Hemione replied.

"The guy that calls you mud blood?" I asked.

"Yes,"

"But he hates mudbloods!"

"But I am not a mudblood," She whispers.

"What," Ron says in shock.

"I am a half-blood." 

Ron POV:

She can't be a half-blood. This is probably a prank or a dream. Hermione brushed away her tears and got up and says she was going to talk to Percy. 

"If you need someone to talk to -"Thalia starts.

"I'll go to you. But I want to see how Percy is doing,"

"Ok, "Thalia replies.

Hermione leaves to talk to Percy. Whoever that is. I immediately attempt to attack Thalia when she defended herself and put a knife at my neck.

"Don't test me, "Thalia says. She lets go of me and turns to a black hair boy.

"Nico, do you want to train?"

"Sure," Black hair-Nico said.

They both leave, and I turned to Harry.

"I think she is controlling Hermione,"

"She's not," Harry says quietly. "Hermione acted the same way as before. She just looked sad," He replies. I can't believe this! My own best friend doesn't believe me. I am going to eavesdrop on Percy and Hermione.

Hermione POV:

I see Percy sitting at the edge of the water.

"Percy?"I ask.

"What?"He asked.

"Are you okay?"

"No,"

"Do  you want some of her old things?" I ask.

"...Yes," He said quietly.

"I hate to ask you right now, but can you tell me the new prophecy and what you are in charge of?" I ask.

"That's no problem," He replies. "The new prophecy is:

Three shall go west

one to heal a broken heart

one to find what she never did before

One to find love

to learn magic

world's collide

and new enemies and new allies are made.

And I am in charge of lakes, rivers, sea animals and horses. I am also an Olympian, "Percy states in Greek.

In Greek: "Why are you talking in Greek?"

"We are being watched."

"Oh ok,"

"Do you want to train with Nico and Thalia?"

"Sure," I reply in English.
