A/N: Yeah, I'm back. As it said / says in my bio, I wanted to finish some of my German fics first. Well, L'autre papa is nearly finished and Heaven & Hell has progressed good so far so I started to type the next chapters for IA. I also went through the old chapters and corrected the mistakes I found.

Special thanks to my beta, JE.

This chapter will answer some questions, the main one being: Who is the werewolf and how come that he helps a vampire?

Severus carried Harry while he was following Lupin.

Remus Lupin. This man had come to help his childe and him. The last Severus had heard of the werewolf had been that he'd started a little journey with the mutt, Sirius Black. That had been about… 12 years ago, a little less than a year after Harry had disappeared.

Severus had never missed the werewolf. Why should he? While vampires didn't dislike werewolves, they didn't like them very much either.

It had to do with the nature of vampires and werewolves: Most werewolves didn't want to be 'dark' creatures and tried to fight their bloodlust and what they called their 'inner wolf'. What most of them didn't know – or didn't realise – was that they were both wolf and human in one. Normally when a werewolf had killed enough he was sated. Would they kill while in human form, the wolf's mind wouldn't take over the body. Werewolves would have total control on the full moon.

Werewolves fought their nature, vampires didn't. That was the difference. The werewolves simply couldn't understand why somebody would kill out of bloodlust or why after doing this they would be 'normal' again.

Of course there were always the occasional vampire that didn't want to feed or the odd werewolf that killed. Well, everybody is an individual.

"Where are you leading us, Lupin? Granger and her little dusting squad are in  town and I would like to get away in one piece." Severus growled out.

Remus sighed. "Just follow me. It's slightly out of town and up a hill. Sirius is waiting there."

"So your little lapdog is with you as well. I should have known that. Tell me, what does he think of his godson being a vampire?"

Remus stopped walking and turned around. Severus noticed an odd expression in his eyes, as if Lupin was… sad?

"Nearly five years ago, there was a little accident. You see, I could smell what had happened once Harry returned to Hogwarts after the battle but I didn't want to intrude on his privacy. When he left I assumed you had sent him to one of your friends or let him go to explore the world.

When a year later a friend of mine from Russia called that a Daywalker had been seen killing a muggle, Sirius and me went to find out who it was. We followed Harry from there on. We could never catch him, but we stayed hidden very well. Five years ago he hunted down a veela. We could have gotten him there and then, but Sirius had looked at the wrong calendar month. The following month would have been a lunar eclipse. The current one wasn't."

Remus grew silent. A minute later he finished, so quietly that Severus nearly didn't hear it: "I bit him. Right in the chest. His first transformation was already the next day. Him becoming a werewolf went very fast. I assume it was because of his animagus form and myself."

Remus abruptly turned around and resumed walking. Severus quickly followed.

~So Lupin bit Black? I knew that it would happen one day . And they followed Harry thirteen years? My little one must have been very good  at hiding himself then. If they couldn't get him.

But what about Harry? A year after he'd left he started killing. Why?~

Another thought hit Severus.

~Lupin said he'd killed a muggle. And nobody ever noticed his murders before. So he was good at hiding them. That leaves vampire bloodlust insanity out of the question. Then he wouldn't care who saw the murder. What else could he have that…~

It was like finding the correct formula for a tricky potion. Severus eyes seemed to have been opened and he just knew what was wrong.

Anaemic.

Harry was anaemic.

Severus would have nearly laughed. Humans that were anaemic had severe problems once turned. The first one or two years, nothing would happen, but then the problems would begin. They'd have to deal with things such  as more hunger and a nearly hurting need for fresh blood very often; problems with the psyche of the vampire, arising from his lack of blood eventually leading to a raving mad vampire if he or she wasn't cared for and cured.

And Harry had been on his own for thirteen years.

Severus followed Lupin and prayed that his childe would be alright.

~*~

At the same time, Hermione and her team were scanning the part of the town where the storehouses were located. Since their discovery about Severus the dead shop owner had been found. It had not been a pretty sight.

Dean and Seamus had tried finding Severus and Harry – although they didn't know it was Harry – but hadn't gotten a result. So now the group had narrowed down the places a vampire could hide and started checking every storehouse in the area.

~*~

Finally they arrived at the old house Lupin had mentioned. It looked a bit rundown but not like a ruin. Severus thought it decent for their purposes.

Remus opened the door and ushered Severus in.

"You can take the second door. It's the living-room. Put him on the couch." Severus did just that and smoothed Harry's hair.

Harry looked older now. Not with his body, but from the lines on his face. His eyes were dilated and he seemed to stare into nothingness. It was like looking into a lunatic's eyes. No. Severus did not want to think about that.

Severus heard Lupin shouting for Black but didn't care about that instead he opened the front of Harry's robes and pulled up the shirt to see Harry's stomach.

Harry was hot, Severus had noticed that already while carrying him, but here he could see it plainly. His torso was slightly red from the blood being heated. A Daywalker's body was not made for hot blood.

"Harry! What happened to him!" Severus turned around. Sirius Black looked much like he always had, except maybe the few grey hairs he now possessed. Against popular belief werewolves did not age faster than humans but a bit slower. They were just getting grey hair faster, which had to do with the fact that grey was a standard colour for wolfs hair. A werewolf could just as well get black or white hair.

"Lupin, I need food. Human food. Many vegetables would be best and something with blood building ingredients."

Lupin seemed puzzled so Severus quickly explained what was happening to his childe.

"Harry is anaemic. Once an anaemic human is turned, the vampire can get severe problems. I fear if we don't help him soon, permanent brain damage will be done."

Sirius paled. "Brain damage?"

"He will go and stay mad."

In an instant Black and Lupin were bustling around the house trying to find the things Severus requested. In the meantime Severus bit his wrist and pressed it onto Harry's mouth. "Drink up. That'll help you." Harry didn't understand what exactly was said, but every vampire knew what this gesture was so he drank on auto-pilot.

Severus only pulled away when he felt himself getting dizzy. Harry's eyes had returned to a nearly normal level and he didn't cough anymore.

"Sev…" he croaked. Severus shushed him.

"Snape. Do you need anything else?" Black and Lupin had brought him the requested vegetables. "At the moment I can't do much. I need to get him to my lab at Hogwarts. He needs some potions and after that  a lot of highly magical blood to even out his anaemic."

Sirius eyed his godson. "But he will be alright?"

"Physically, yes. Psychically, I don't know for sure." ~But he was never completely sane in the first place.~

Sirius frowned. "How do we get him to Hogwarts? We can't use floo and using a broom or apparating is out of the question for Harry."

Severus knew this, but Harry needed to get to Hogwarts, and fast.

"Granger has emergency teleport-stones with her. They lead to Hogwarts in case should the group be hurt too much. Poppy had been told to tend the wounded. We could get a stone from them."

Lupin frowned. "Hermione and the others don't deserve to be attacked by us. And I doubt they would give up the stones willingly."

Severus growled. "Granger and her team want to kill the Daywalker. They said as much. If they get Harry, they will either kill him or send him into prison, which would lead to his death as well."

Remus sat down while Sirius paled. "Nobody hurts my godson." he stated. "And if we have to attack Hermione and her team, then we have to do it. We could always make a dash for the stones and try to avoid hurting them more than necessary."

Remus sighed. "Once we attack them, they will hunt us down. We won't be safe anymore, not even at Hogwarts. Minerva does not stand for such things and you know it."

Severus agreed with Lupin. If he could get Harry out of here fast and unnoticed, the killings would simply stop and nobody would think anything about it. And Harry wouldn't have to go to jail. His once friends would never know it was him.

"Maybe we can steal the stones." Remus and Sirius turned to look at Severus. "I will create some illusions and take the stones. You two will guard Harry and keep his temperature as low as possible. Ice won't help, it's a magical fever. But cooling charms may be able to stop the heat from rising higher. If he awakens get him to eat the vegetables. Once I'm back we'll bring him to Hogwarts."

Remus nodded. "Alright."

Sirius sighed and sat down next to his godson. "Be back soon, Snape. I want my godson to be healthy once again."

Severus bit back the comment on Harry being undead and therefore not exactly healthy and walked out of the house. He needed to get a teleport-stone and that as fast as possible.

"I found something!" Neville's yell echoed through the storehouse. Soon everybody was at his side, glancing down at what appeared to be a pool of blood.

"What's that?" Ron asked.

Draco kneeled down to touch it. He sniffed at it. "It reeks of death. This blood belonged to an undead."

The group stood for one moment in stunned silence. Then Neville spoke up.

"Do you think Snape found the Daywalker and fought with it?"

Ron snorted. "After the tantrum he threw about us going to kill his childe? Not likely."

"Well, something did hurt the Daywalker." Seamus pointed out.

 Draco began to draw little circles with his wand. "What are you doing there?" Dean asked.

"I'm trying to find out if there was another non human here. Maybe this spell works."

Soon a word written in little silver letters appeared on the ground next to the pool of blood.

"Werewolf." Draco read out loud.

Dean sighed. "So, there is a werewolf hunting the vampire? That's good news, isn't it?"

Hermione frowned. "Well, where are the werewolf and the vampire?"

This was the question nobody could answer.

Finally, Blaise sighed. "At the moment we can't do anything. We have to monitor the city for special magical energies, such as illusions I would say. And if there is indeed a werewolf hunting the vampire, it could be possible that we won't have to put up with him much longer. So I would say that we go back to the base and stay there while we ask around if anybody knows of a werewolf coming into town. When we checked the city documents of the inhabitants there were no werewolves listed."

Hermione nodded. "That's a good idea Blaise. There isn't really much we can do at the moment." She sighed. She wished she could do something, but it just wasn't possible at the moment. God, how she hated  times like this!

Ron's eyes had a sad touch in them. "You know, I bet Harry would have properly found the vampire and fought it one-handed." He chuckled sadly. Neville, Seamus und Dean smiled a bit and Hermione nodded in sad agreement. Draco couldn't help but nod as well and Blaise stared at the pool of blood, asking himself what would happen if The Boy Who Lived turned out to be The Boy Who Was Undead and decided to attack them.

Somehow a fight seemed pointless in Blaise's opinion. Harry Potter had been a very powerful wizard and with Severus Snape at his side, a few humans wouldn't be able to stop him.

A/N: Review Answers:

Myk: Yes, it is Remus. Sweet, sarcastic Remus.

Runespoor: On Slytherin's grave? Wow. And I always could see Remus Lupin with such a smile. I think it rather suits him. At least in a dark story.

Myst4Drgn: Here is Sirius!

I G Senkel: Well, was it really him? I bet it was. It was a bit obvious, wasn't it?

Sam: Blaise will play a big role in the future. As to why Harry's sick, that should be explained now.

Lirael: I hope this already explains a bit about Remus… biting his lover really would damage him I think.

Raven of the night1: Sorry, but I really didn't want to update sooner… my WIPs needed some attention badly.

Lea Black: They won't find out… yet. After all, Harry Potter in Hogwarts will stir some things.

Ancalyme: Well, this chapter explained a bit of what changed Remus. But that's not all. And Ron and Hermione are on my 'don't like them' list. So expect them to get into trouble and encounter many, many problems.

Blood Aura: I will continue, don't worry!

And to everybody else who reviewed: THANKS! Your reviews really mean much to me…
