Hi Readers!

Don't forget to give some feedback. It really helps.

I think I've rewritten this chapter about five times before finally getting it right.

Enjoy!

Chapter 1

- Who is he? -

13 years later...

"Teddy! In here!" Teddy turned around and smiled when he saw Ron calling him towards their compartment. Dark circles hung under the boy's eyes and a bandaged covered a scratch on his shoulder. "How did it go? The full moon I mean. That was three days ago right?" Ron asked curiously.

Teddy was about to reply when he noticed the strange man that was leaning against the window. He appeared to be asleep but Teddy wanted to be sure. It wasn't a secret that Teddy had part of the werewolf gene, the whole school knew, but even then he wasn't comfortable talking about it in front of a stranger. "Is he-"

"He's asleep... I think" Hermione said shrugging and Teddy nodded, sitting by the window, exactly opposite from the man.

"Who is he?" He asked in a half whisper, so not to wake him.

"Professor R.J. Lupin." The smart witch replied. Teddy zoned out as Ron began to complain about how Hermione knew everything. A strange feeling had crossed Teddy, it had started from the minute he'd entered the compartment and then increased when he heard the professor's name. It was a feeling of familiarity, as if he knew this person, or should know him. The name was familiar but he couldn't guess why.

"Do you think he's really asleep?" Harry asked.

"I think so." Teddy leaned slightly, but could hardly see the man's face, which was covered by his cloak. "Why?"

"I gotta tell you guys something." Harry closed the door to the compartment. Teddy listened intently as Harry explained what he'd learnt. "So let me get this straight," Ron said, a little flustered. "Sirius Black escaped for Azkaban... to come after you?"

"Yeah." Harry nodded, adjusting his glasses and wiping his forehead, revealing his lightning shaped scar.

"But they'll catch Black won't they? I mean everyone's looking for him." Teddy said, trying to reassure his friend.

"Sure," Ron shrugged but looked doubtful. "Except no one's broken out of Azkaban before, and he's a murderous, raving lunatic."

"Thanks Ron." Harry said sarcastically. Suddenly the train came to a sudden stop, so hard that Teddy nearly fell on Professor Lupin. "Why have we stopped?" He asked.

"We can't be there yet." Hermione said, trying to get up to peer outside the compartment door, then the train wobbled again, forcing his to stumble back into her seat.

"What's happening?" Ron's panicked voice said.

Harry clutched onto the seat. "I don't know."

"Maybe we've broken down? It wouldn't be the first time, one the train broke down, they arrived at Hogwarts the next day and-" Teddy never finished his sentence as the lights went out. There was a shuffling and Teddy winced. "Ouch! Ron that was my foot!"

Ron had crawled over Teddy and was staring out the window. Outside it was pitch black and rain was falling heavily on the window. "There's something moving out there." His voice wavered and Teddy could see why. The edges of the windows were beginning to... freeze? "I think... someone's coming aboard."

The train shook once again and Ron screamed. "Bloody hell! What's happening?" No responded, the train had gone deathly silent. The window was covered in a murky layer of ice and a cold chill had entered their compartment. Teddy felt a sharp pit in the depths of his stomach. He didn't know how to explain what he was feeling. It was as if the happiness had been sucked out of him and was replaced by feelings of fear, anger and loneliness.

The lock on the compartment flicked open making Teddy jump and freeze. Behind the door a shadow figure hovered above the ground, covered completely in a long black cloak. The creature hovered into the compartment, looking at them one at a time. It appeared to be leaving before its eyes fell on Harry. Well, more like when he faced Harry. The creature's eyes couldn't be seen as they too were covered by the cloak.

There was a terrifying breathing noise as if the creatures was taking a long raspy breath. Harry had gone ridged and was shaking violently, grunting softly. The creature floated closer to Harry, who had turned extremely pale. Suddenly, Teddy noticed the man move slightly. His green eyes flicked open and he stood up and pointed his wand at the creature.

A wave of light shot out from the tip slamming into the creature sending it flying away. The light was so bright that Teddy covered his eyes from the glare, he heard a thump as Harry fell to the floor unconscious.

Soon the lights were back on and the train was moving. The man had sat opposite the unconscious Harry, trying to wake him. Now that Teddy could see his face, the feeling of familiarity increased. Where had he seen this man's face before? "Harry. Harry are you alright?" Hermoine said as Harry regained consciousness.

Teddy silently scolded himself. Here he was, wondering where he'd seen this man's face before, will his friend was lying on the ground, looking as pale as death. "Here, eat this." Professor Lupin said, holding out a small block of chocolate. "It's all right, it's chocolate." Harry took it yet didn't take a bite. Professor Lupin began to hand out chocolate to the others.

Teddy noticed that Professor Lupin looked at him strangely, as if he too seemed to recognise Teddy from somewhere. The Professor plastered on a warm smile and handed him the chocolate. "What was that thing?" Teddy asked, taking a bite of the chocolate and almost groaned at the warm feeling that grew from his chest.

"That was a Dementor. One of the guards of Azkaban. It's gone now."

"What did it want?"

"It was most likely searching the train for Sirius Black. Now if you'll excuse me, I need to have a little word with the driver." He got up and moved to the door, he turned around and noticed that, besides Teddy, the others were yet to eat their chocolate. "Eat. You'll feel better." Then he left. Teddy watched him go but again mentally kicked himself, for not helping Harry.

"What happened to me?"

"Well, you sort of went rigid." Ron explained. "We thought you were having a fit or something."

"And did you guys... you know... pass out?"

"No," Teddy shook his head. "I felt weird though, as if all my happiness was taken away from me."

"But someone was screaming, a woman." Harry sat up, nibbling on his chocolate.

The three friends looked at each other before glancing back at Harry. "No one was screaming Harry."

Teddy leaned against the window, his eyes tired and drooping. They were about an hour away from the school now and Teddy took that chance to rest his head and fall asleep. Although his transformation was four days ago, he was still tired and soar many days afterwards. He was asleep by the time Professor Lupin returned and quietly sat down opposite Teddy. "I see your friend's all tuckered out." He grinned, his tired eyes shining.

"Teddy's always tired after-" Ron began but Hermione's elbow dug into his side. "Ow!"

"Ron!" She said through gritted teeth.

"What? He's probably going to find out anyway." He whispered.

"It's not for us to tell." She hissed, glancing at the Professor. But he didn't seem to be listening, in fact he was lost in thought. "Teddy... what's his last name?"

"He doesn't have one." Ron said, stuffing the last of the chocolate in his mouth.

"He's an orphan sir." Harry explained and Lupin was quiet for the rest of the trip.

The others had awoken Teddy a few minutes before they arrived, giving him time to change into his robes. When he had woken Professor was no where to be seen, had he come back? He ignored the thought and climbed into the carriages, drawn by non-existent horses and rode towards the castle. Teddy was excited, he couldn't wait to finally sit down in the warm hall and feast to his heart's content. The only problem was that he wasn't allowed to sit next to his friend's, at least not for the first dinner.

Not because of his lycanthropy, but because he wasn't a Gryffindor, he was a Ravenclaw. Because of this he couldn't visit him friend's in each others common rooms and couldn't sit with them during the first and last feast of the year. Worst of all was that he couldn't even sit near his friends, due to the Hufflepuff table between them.

Teddy sadly said his goodbye's before sitting at the Ravenclaw table. As usual the other Ravenclaw's would sit at least one seat away from him, only one dared to sit near him. "Good afternoon Teddy." Luna Lovegood greeted. "You look awful." He just smiled slightly and nodded, glancing up at the staff's table. Professor Lupin was sitting next to Professor Snape who refused to even glance in his direction. Professor Lupin was talking with one of the other Professors.

"You okay Teddy. You've been staring at the Professor for a while now." Luna interrupted his thoughts.

"Huh? Oh, sorry I was just-" The doors to the Great Hall opened and all the first years came wandering in, led by Professor McGonagall. A few minutes later they'd all been sorted into their houses. Teddy listened in on the conversations between the Ravenclaw seniors and first years. He heard a series of introductions, questions and quiet whispers of delight. Among all the conversations he noticed the first years looking at him, while the seniors whispered in their ears.

Great. He'd been at Hogwarts for two years now and he was still one of the school's hottest topics.

"Remus," Dumbledore spoke and the young Professor looking up smiling. The Headmaster gestured for him to follow. The two walked into a room where they could be alone. "Is something wrong Professor?" Remus asked nervously.

Maybe the Headmaster had reconsidered his idea to ask him to teach Defense Against the Dark Arts? After all, the only reason Remus had agreed to do take on the position was because of the endless supply of Wolfbane potions he'd been promised.

"Not at all Remus." Dumbledore raised a hand to calm him. "I wanted to thank you for your actions on the train."

"Oh," Remus was going to defend himself, saying he didn't deserve his thanks but Dumbledore continued.

"I'm aware that you met one of your third year students, Teddy." Remus gut churned and he pushed away his suspicion.

"Yes, I did."

Dumbledore gave him a knowing glance as if he could read his thoughts. "I apologize Remus, I didn't tell you everything when I asked you the position of Professor."

Remus tugged at his coat subconsciously. "What do you mean?"

"Teddy... isn't one of our normal students." The wise man began stroking his long snow white beard. "Like you, he has the lycanthropy gene." Remus sighed, feeling sorry for the kid, who would be going through the same trauma he did when he was young. "And, I was hoping that you could-"

"That I could keep an eye on him." Remus finished his sentence and Dumbledore nodded. "Of course Professor. Do you wish me to accompany him to the Shrieking Shake when needed?" Because of the Wolfbane potions he was promised, Remus planned to shift in his office and stay there for the night, but he guessed that Teddy would go to the shack.

"That won't be necessary as he has no need of the shack."

"What? Do you keep him somewhere else?"

"Yes... and no. Due to parent and student complaints, Teddy has been given him on room on the opposite side of the castle, closest to the Dark Forest."

"But... if parents are complaining then..."

"Everyone here knows of his lycanthropy, I informed them when Teddy first came to Hogwarts."

Remus thought Dumbledore was insane. Sure Teddy wouldn't have to worry about hiding his condition, but wouldn't it be safer if other didn't know. "Sir-"

"He only carries part of the lycanthropy gene Remus. He can control himself even after his transformation. On full moons we lock his door, his room is filled with charms to keep him in and others out."

Remus' gut dropped again. In the back of his mind he was connecting the dots and he feared what it meant. "He's... not a full werewolf?"

"I know the question that you refuse to ask Remus, so I will answer it. Teddy's full name is Tesdon 'Teddy' Lupin, he's your son and no, he doesn't know who you are." Remus had to sit down. "This is what I regretted not telling you. I will completely understand if you want to leave-"

"No." He replied, looking into the fire. "No, I ran away from him once. I won't make the same mistake again." Dumbledore smiled, placing a hand on the Professor's shoulder. The fire crackled, casting weird shadows across the wall. The Headmaster walked towards the door, half opening it. "I'd better go address the students and introduce them to our newest Defense Against the Dark Arts teacher."
