Ravenclaw125: Good guess but no sorry but there will probably be a relation of his in it! :D
His parent probably won't be revealed for a while, I'm not sure. Oh, and when Hermione thought Nico was talking to someone in his head or thinking, he was actually asking Hecate for higher magical abilities because Percy told Hermione he was advanced.

PERCY POV
I was very confused. So, maybe there is two reasons Annabeth calls me seaweed brain. I had woken up in the middle of the night to see Nico and Neville's beds empty. I wasn't thinking straight, because it was the middle of the night, so I tried to find them. I followed Filch, saw the scene, and was about to say hi (or maybe something a bit more dramatic) when they disappeared. Which had me back to the beginning.
I ran around the castle looking for them until I bumped into a lady, who's name I learned was Madame Pompfrey. She told me to follow her to the hospital wing and scolded me the whole entire way. When we got to the hospital wing, I finally saw Nico and Neville. The two demigods managed to fill me in, finally, but I didn't really get the whole 'blockage of powers' thing.
We waited for the mystery boy to wake up, and I was nearly about to drift off when he sat up suddenly, his green eyes wide, making me jump and fall of the chair.
"Who are you?" he asked, just as Neville said the same thing to him.
"I'm Percy," I offered, and let the rest of the group introduce themselves, which varying amount of caution. (Code: Nico)
He hesitated, before saying, "Jackson Montuaire," (A/N: I feel like I've heard that last name before, does anyone know where it's from?) I was kind of suspicious, but I shook it off.
"Are you a demigod?" I cut straight to the chase.
He hesitated again. "No?" He saw our disbelieving looks. "Okay, fine, yes."
"I knew it!" Nico sounded triumphant, and I was sure I saw Neville secretly pass Nico three drachma.
"Who's your godly parent?" Dumbledore asked.
I could of sworn he looked guilty. But in a flash the guilt was gone. "I...can't tell you," he said.
"What do you mean?" Neville looked confused.
"I-er-I'm under orders?" It came out more like a question.
"You're a really bad liar," Nico informed him.
"Maybe we should, like, go back to bed and come back in the morning," I said. Dumbledore was about to agree when Harry came running in. I was half (okay, who are we kidding, I was entirely sure) he was about to accuse us of treachery or for being out of beds, but he had eyes only for Dumbledore.
"Dumbledore, come, please!" he panted, like he had run all he way from his dormitory. He probably had. "It's Hermione! She...came in...and wanted to find out more about them," he listlessly waved a hand in my direction, "and it didn't...go well,"
Dumbledore stood up straight. "Neville, Nico, Percy, come with me. Harry, lead on."
"Hey what about me?" Jackson asked, scrambling out of his bed. When his feet touched the floor he winced and clasped a hand to his stomach. He shook his head when I asked if he was okay, and wheezed something about 'stupid monsters'. He carefully sat down on the bed again.
"Ambrosia?" I carefully whispered to all four demigods in the room, so an increasingly impatient and worried Harry wouldn't hear. They all shook their heads, Jackson wincing when he did so.
"You guys go on. If Hermione is as bad as Harry is making it sound, you'll be coming back here anyway." Jackson exhaled quietly.
I nodded. "Let's go,"
CUPCAKES-THIS IS A LINE-CUPCAKES
Once we got to the common room, Harry headed up the stairs to the boys dormitory.
"Wait," Nico said, halting. "Why are we going to the boys dormitory if Hermione is a girl?"
"Well, er, I wanted to stop her, I swear we tried, she just reached for his..." he looked at Nico.
"My what?" Nico asked, before running up the stairs. I followed.
Hermione was laying in the middle of the floor, eyes glassy and opened, not moving. A frozen hand was reached out in front of her. Ron and the other occupants were staring aghast at her. Nico rushed forward and laid a hand on her forehead. He rose with a grim expression. "She went through my stuff, didn't she?" he hissed, glaring at Harry and Ron.
They nodded reluctantly. "We woke up just as she was reaching for it. We tried to stop her..."
Some part of my brain registered they had said that three times now, but I was too worried for Hermione (well, more like the fact bad things would happen to us if she didn't wake up)
I drew Nico close. "What happened?"
"Well," he took a deep breath. "You know how the power of the water sometimes protects your stuff, like that time Connor snuck into your cabin and ended up with an octopus on his head? Well, what protects my stuff is..."
"Death... Will she die?" My voice sounded eerie.
Nico shook his head. "My father isn't that cruel, Percy. It depends on her intentions. I'm guessing she was only curious and slightly suspicious."
Slightly? I wondered, just as Dumbledore came over. "Do you know what happened?" he asked.
We filled him in. "How do you reverse it?" he asked.
Nico made a face. Then, looking around, he whispered, "Not here. Dumbledore, can we go to your office?" We called Neville over from where he seemed to be whisper-fighting with Harry and Ron and he ran over, looking relieved.
I wondered if Hermione would try that stunt again in a hurry. Maybe next time, she wouldn't be so lucky as to just been in-well, whatever state she was in now. A powerful son of Poseidon and the son of the Dead...well, let's just say us two are not good to mess with.
