Fenrir Greyback stalked through the streets of Surrey under the full moon. He did not bother to contain the growl that continuously rumbled through his chest, causing small animals to dart away in fear. Dogs cowered behind their fences in the hope that the angry alpha canine would not turn his attention onto them.

Fenrir just ignored everything as he continued to stalk through the shadows. He had long ago accepted his wolf and was able to transform without losing himself during the full moons. He did not even spare a glance for the muggle that had taken his dog on a late night walk and was trying to get his dog to move instead of cowering in a ball on the sidewalk.

The only time that he separated himself from his wolf fully now was when he needed to make an appearance among witches and wizards without them knowing that he was the feared Fenrir Greyback, a name that he had given himself when he had first accepted the wolf. He was still surprised that no one had ever made the connection between Fenton Grey and Fenrir Greyback; the only real difference between the two was that Fenton had blue eyes and was not as scruffy, and a bit less likely to gut someone. Even the Dark Lord had occasionally commented on the stupidity of the wizarding world.

At the thought of the Dark Lord, Fenrir growled loudly enough that even the muggle heard it from his place on the sidewalk. After looking around, he scooped up his still cowering dog and made a run for it. Fenrir just glared at the muggle as he ran. With a huff of breath, he returned to his shadow stalking. He knew that the old man would be bringing the blasted baby here somewhere since he heard the oaf Hagrid tell Black where he was going before taking off on the motorcycle.

He had been waiting outside for the Dark Lord to finish dealing with the whelp before joining him and returning to the manor that they had been using. Fenrir was the only one of his followers that he had taken with him on the night that he would destroy the Potter family completely. Instead of everything going as planned, Fenrir watched as the house seemed to blow up. Then, on top of that shock, he learned from Black and Hagrid that the baby survived somehow and the Dark Lord was nowhere to be seen.

One thing that was bothering him though was why the old man had sent Hagrid to take the baby away instead of coming himself. The Dark Lord had speculated that the old man had some type of ward on the house that would alert him if they Potters were in danger, so it did not make much since that the old man had never shown up. This whole night is turning out to be a nightmare.

Finally he turned the last corner and found himself looking at number 4 Privet Drive. Honestly, how secure does the old man think this is? All the upper level Death Eaters know where each of the muggle order members muggle families live.

Tilting his head to the side he sat back on his haunches and watched the baby that was sitting on the doorstep of the house across the street. After a few minutes of watching to make sure that there were no other magicals in the area, he stood, stalked across the street, and growled at the baby. He intended to enjoy getting revenge for whatever the whelp did to the Dark Lord, a man who had helped him when his family had abandoned him because he had been bitten. The Dark Lord had then helped him claim his inheritance by taking him to Gringotts. His father had died before he ever knew that the boy he had cast out would make something of the Grey family once more.

The one and a half year old Harry Potter had awakened to find himself wrapped in his blanket outside some strange house he had never seen before. Looking around, he could not see anything or anyone that he recognized other than his blanket. He did, however, find an envelope in his blanket that he proceeded to gnaw on. His mummy had said that he was getting another tooth and that is why his gums were hurting. He pulled his blanket closer as the cool night air caused him to shiver. Distracted as he was by the cold and by gumming the envelope as hard as he could with his swollen gums, he did not even notice the large werewolf stalking up to him until the werewolf was standing over him and growling. Harry Leaned back so that he could see better.

"Doggie!"

Ears on top of the massive head twitched in irritation at the excited squeal from the toddler. Stupid baby doesn't even know when to be scared. Rolling his eyes at being called a 'doggie' of all things, Fenrir tried to look as menacing as he could as he shoved his nose into the belly of the baby. He wanted to make sure that this was the Potter brat before he started to eat a random child.

With another squeal, Harry grabbed the fur on the head of the werewolf that was tickling his tummy. "Doggie!" He then began to wave his slightly damp envelope in the air as he babbled to the werewolf that was now sniffing him all over.

Fenrir was confused. He knew that this baby was magical, he could literally smell it. The baby seemed to be covered in some sort of masking spell however. If he had not been a werewolf he would have never noticed that something was not right with the Potter baby. He could definitely smell James and Lily Potter on the boy, but it was not the natural sent of the boy. There was something underneath that he was trying identify. He knew that he had smelled that sent before. It was hard to concentrate when the boy continued to giggle like a demented mini demon. Finally he paused with his snout pressed against the boy's neck and took a deep breath. Fenrir reared back in shock and stared down at the giggling little boy before him. A boy who carried the scent of his best friend, Regulus Black.

It had been a huge blow that left the Death Eaters shocked when they found that Regulus had been murdered by the order. They had known that the light was capable of anything, but had been unprepared to find one of their own had been killed while unarmed in his home. It was suspected that it had been James Potter that had cast the cutting curse that caused the death of the Black heir, causing anyone with the name Potter to be at the top of the most hated list for the Death Eaters.

The Dark Lord had sworn the night they laid the body to rest that he would destroy the Potter family for killing the young man he had adopted as his magical heir. The fact that the child of the Potters was a possible child of prophecy with the power to vanquish the Dark Lord just added to the urgency of the matter.

Fenrir tilted his head to the side as he contemplated what he should do with the boy now. He could not just eat him until he figured out what was going on with the boy's scents.

Harry was once again gnawing on the envelope but now was yawning every few minutes and rubbing his eyes. With a huff, the werewolf stood and shook out his fur, gaining the attention of the small boy before him. Harry gave him a gummy smile around his envelope and cuddled his blanket closer with a shiver.

Fenrir nudged the boy with his snout until the boy fell over with a soft plop and giggle. He continued to nudge the giggle monster until he was situated on his tummy. With one last huff, the werewolf gripped the back of the footie pajamas that the boy was wearing between his teeth and walked away from number 4 Privet Drive with the toddler dangling from his mouth, much like a wolf cub, still clutching his blanket and gnawing on his envelope as he dangled from the predator's mouth.

The occupants of number four never even stirred from their sleep.

Then next morning, Fenrir woke up with something poking him in his cheek. He grumbled and tried to swat the annoyance away, but it just came back and poked at his cheek again. He finally opened his eyes when something started to pull at his lips. He did not know of any insects, muggle or magical, that could be this annoying.

He was greeted by a frowning Harry Potter, who was sitting right beside his head and poking and pulling at his face.

"Doggie?" The boy whimpered.

Fenrir sighed and sat up, pulling the small child into his lap. "I am not a dog, brat. I am a werewolf." When the boy just stared at him with liquid green eyes and a trembling lower lip, the werewolf sighed again. "How about we get out of here and we find out why you smell like Reg covered with Potter?" Fenrir was thrilled when the boy just tilted his head to the side and stared at him while chewing on one of his fingers. He was not equipped to deal with a crying baby. To be honest, he was not equipped to deal with a baby period.

Looking around, he noticed that they were nestled into the hollowed out tree trunk in the middle of a random patch of woods outside of Surrey he had found the night before to stash his wand and clothing. After pulling on his clothes he quickly found the blanket that the boy had been left with and the chewed up remains of an envelope. Looking the letter over, he realized that it had been written by the old man himself. Giving it a sniff, he noticed that there was magic clinging to the parchment inside the envelope.

"Let's see what the old man had to say before we go, right brat?" Harry just gnawed on his finger. Avoiding the side that had been chewed on, Fenrir opened the envelope and pulled out the letter. He immediately felt a wave of compulsion charms wash over him and he quickly worked to shrug them off. The Dark Lord had insisted that his Inner Circle be able to throw off the Imperius other possible spells that could influence their minds. Fenrir was now very thankful for the rigid training that he had gone through. "Why would the old man need to use compulsion charms on muggles?" Reading through the letter, the werewolf began to snarl and growl in anger. He jerked back when a small wet hand patted him on the cheek.

"Doggie sad?" Harry was staring up at him with those big green eyes again. He had, while Fenrir was distracted, made himself at home in the werewolf's lap.

Fenrir rolled his eyes and sighed. "I am not a doggie…Fenrir, say Fenrir."

Harry stared at him before smiling. "Fen!" Harry began to bounce in his lap and repeat his new word happily. "Fen Fen Fen Fen Fen Fen."

"Sure brat, whatever." Standing Fenrir spelled the leaves and dirt off that he had accumulated while sitting on the ground. He was forever thankful that he was a wizard and could use magic to make his life easier. He then turned to the still babbling baby and spelled him clean too. He had been starting to smell a bit ripe and he was not changing a dirty diaper like a common muggle.

"Alright brat. I am going to take you to Gringotts and we are going to find out why you smell off. Then, If you are a Potter, I am going to kill you. If you are not…well, let's just see what the Goblins say." Fenrir cast a quick glamor charm over the boy to make sure that no one would recognize the boy as a Potter while in the alley. Fenrir then made sure to push back his inner wolf so that he would not look like the man known as Fenrir.

Making sure that he had a good grip on the boy, he apparated to Diagon Alley.
