Disclaimer-I don't own Danny Phantom or Harry Potter all I have are any OCs that may appear

I am changing things quite a bit in this chapter. Sorry about the delay I've had a busy couple of months.

Danny tossed and turned in his bed. Images of his family flicked through his dreams. Their voices tormented him with what he already knew. It had been his fault.

"It's all your fault little brother."

"Why couldn't you stay out of there?"

"You shouldn't have been down there."

"You killed us."

"So much misery little murderer."

The voice was unfamiliar and sounded like they were right by his ear. He quickly turned his head in the dream to be faced with glowing red eyes looming out of the dark with a pointed toothed grin barely visible on the mostly unseen figure's face.

Danny shot awake sobbing. Something moved in the dark to his left. His head whipped round. In the dark his curtain shifted and some shadowy form departed through the small gap that he could only tell was present from the small amount of light from the outside world. The curtain fell closed. Danny sat awake staring at the window. What had that been. Danny didn't sleep again that night.

When morning came the first thing Danny did was check the window. He must have imagined the whole thing, the window had never been open. If there was someone in his room they couldn't have left through there.

Danny limped awkwardly down the stairs while Dudley walked towards the door banging his Smeltings stick off the walls. Dudley snatched the mail from where it was stuck halfway through the letter box. He thrust two letters in Danny's direction the one on top was definitely from Sam.

Dudley went pale and gripped tightly the letters he had been passing to Danny. It hadn't been Danny's letters that had bothered his cousin it was something written on the envelope of the next letter down that had set the boy off.

"Dudley? What's wrong?" Danny asked peering over Dudley's broad shoulders to see strange parchment envelope.

Dudley snapped out of it and bolted down the corridor to the kitchen away from Danny. He still had a hold of Danny's letters.

"Hey Dudley wait up you still have my letters!" Danny called limping after him.

By the time Danny had made his way into the kitchen his letters were in front of his normal seat and the mysterious letter was gone. His Aunt and Uncle were avoiding his questioning looks and Dudley looked really nervous. Danny sat down for breakfast trying to remember what had been written on the back of the envelope. H... H he was sure that the name had started with a H. No that was the initial of the first name. What was the last name though? Peters? No but definitely P. Pots... Potter!

"Who's H Potter?" He mused aloud.

His uncle Vernon made a strange sort of strangled noise and went red. "No one!" He snapped.

"That letter Dudley brought in had that name on it."

"He's the person that lived here before us." Petunia stated briskly.

"Oh." With that Danny let the subject drop, clearly his Aunt and Uncle didn't want to talk about this person.

He finished his breakfast and left with the letters. It wasn't till he was half way through reading his letter from Sam when he realised what was wrong. His Aunt and Uncle had lived in the house for as long as he could remember. It had definitely been four years. Would someone really still be trying to contact the person. He knew there had been something else odd about the letter but he couldn't remember what it had said after all he had only glanced the green lettering.

That night the nightmare returned.

"It's all your fault little brother."

"Why couldn't you stay out of there?"

"You shouldn't have been down there."

"You killed us."

Red glowing eyes loomed out of the darkened lab. Pointed teeth gave a confident grin as the eyes approached. The figure reached for him and the whole place came crumbing down around him. He caught sight of a large lump of ceiling falling towards him, he needed to move.

Danny woke when pain shot through his broken leg as the cast impacted with the floor. He was surrounded by the dark. Someone had come in after he fell asleep and turned out the light. Through the dark it looked like the walls were bowing in towards him. Memories and the nightmare filled him. He needed to get out before the room collapsed on him. Subconsciously he knew it wouldn't or he would have tried to wake his remaining family. Using his crutch that was beside the bed he forced himself to stand. He was taking quick frantic breaths feeling like there just wasn't enough air in the room. As quickly as he could manage he got himself out of the room. The upstairs corridor was worse. He knew it was narrow but now it felt like there was barely enough room to pass through. Hope pierced the panic in the form of light coming in through the front door window from the street-lights outside. Outside there would enough space.

The stairs was a challenge, it was easier to go up because he could just use the crutch to pull himself up. He got down onto the landing when it felt like his legs had decided to fall asleep on him. The pins and needles style tingling spread up from there and within the same minute he was falling into pure darkness as the solid surface of the landing gave way beneath him.

After the incident at the Zoo Harry had been in his cupboard practically 24/7. He had one free week but that had been spent at Ms Figg's while the Dusleys had gone to America to pick up the cousin he had never met. Other than that he had only been out at night under the instruction of his aunt to only be out long enough for food and to use the toilet. The Dusleys had been very adamant he and his cousin were not to meet. All he knew about his cousin was that the boy had recently lost his family in an accident.

Harry was half awake and contemplating leaving his cupboard for a little to stretch his legs. It wasn't fun being in this cramped a space for so long. He shifted to get up but stopped when he heard the thumps of movement in the upstairs corridor. At first he thought it was uncle Vernon but then realised that every other thump was louder. The footsteps were his injured cousin's. He sighed and settled back down onto his bed, he wasn't leaving the cupboard for a little while. When the thumps reached the landing just above him dust fell and then something a lot larger than the dust bunnies. Harry yelled and had the wind knocked out of him. Whatever had fallen on him whimpered and scrambled away from him.

Harry could just make out the shape of a scrawny figure half curled up on himself. Half because one of his legs was in a cast along with the opposite arm which made curling up actually pretty hard. The figure was his cousin. His cousin was shaking and muttering something over and over again.

Harry pulled the light cord that hung by his head to turn on the light. His cousin flinched away when the light turned on. He glanced up nervously taking in the small space.

He tries to comfort his cousin

"Hey are you alright?" Harry asked crawling down the bed towards him.

"I... I..." He kept casting glances at the walls and the door.

Harry helped Danny out of the cupboard and into the living room. Danny relaxed a bit more in the larger space. Light from the street lamps helped to calm Danny.

Who are you

"Wh... Who are you?" Danny asked.

Harry

"Harry... Harry Potter."

They said you don't live here any more why were you in there

"Potter? Wait but Aunt Petunia said you didn't live here any more. What were you doing in there?"

"That's were I sleep. She's my aunt too. I've lived here for as long as I can remember."

"She lied. Why would she do that."

"They didn't want you meeting me."

"How did you get in there anyway?"

I don't know.

"I... I... don't know. I was just coming down the stairs. Next thing I knew I was falling."

Danny didn't remember falling asleep while talking to Harry but still he woke up back in his bed. He had to wonder if the previous night had been part of the dream he thought he had woke from. It would make sense if it was a dream. He had fallen through the floor into the cupboard under the stairs, people couldn't go through solid objects like that. On top of that why on earth would his aunt and uncle want to hide another cousin from him. His aunt and uncle said nothing about having to carry him back up to bed and didn't ask why he had been down there. That only cemented his belief that it had all been a dream.

There were more letters addressed to H Potter that morning. Who ever was sending these letters was persistent but how did they know that they hadn't gotten to the right person. He wondered if the mysterious letter yesterday had inspired him to invent Harry. Danny was a little clumsier than usual that day.

He was sitting at the desk in his room when he noticed it. His hand was gone. He could still feel it but he couldn't see it. He couldn't take his eyes from the spot where his hand should have been. He used his other hand to prod at the unnaturally empty space. He didn't know how to process what he was seeing. He wanted to freak out but at the same time he just wanted his hand back.

His hand had been invisible. It definitely wasn't normal. Just like the night before hadn't been normal. If his hand could disappear then there was every chance that the previous night had been real. He stood in front of the cupboard door about an hour after he was supposed to have gone to bed along with the Dursleys. He knocked on the door. The door creaked open to reveal Harry stood in the small dimly lit space and Danny could make out the shape of half a crutch sticking out the ceiling. He hadn't even noticed that he had been using the spare crutch. Harry was real and for some strange reason that Danny couldn't figure out they had tried to keep him a secret.

"There was a letter for you and more of them came this morning." He said with a smile.
