As the weeks progressed, Harry began to settle into his dual-role as Hogwarts Professor and Deputy Head Auror in charge of the hunt for Fenrir Greyback. In truth, his position at Hogwarts helped him to hunt Greyback. All sources still indicated that his goal was to target students – in particular, Teddy. Other than the increased Auror presence during the full moon, students were yet to realise the near constant Aurors that were patrolling the grounds. Harry had them trained well.

Friday afternoon, the fire in Harry's office lit up to reveal his wife's face.

"Harry, I need you to come home now," she said urgently.

"What's wrong?" He had fallen to his knees in an effort to scramble towards the fire.

"Just come quickly."

Harry needed no further guidance. Once Ginny's face disappeared from the fire, he stepped inside and Flooed home. Harry fell out of the fire expecting to see a catastrophic scene in front of him. His mind had thought the worst possible outcomes – his kids were injured; escaped Death Eaters had broken into his home; Greyback was attacking his children; Voldemort was back. However, when Harry arrived in his house he was faced with something very different.

"Dada," baby Lily cooed from her baby seat, kicking her legs in excitement of seeing her father. Harry picked her up quickly before progressing through the rest of the house, his wand at the ready. The house was silent and nothing appeared to be out of order – it was nearly too silent. Did he not have two young sons?

BANG.

Screams.

Harry ran towards the source of the noise, taking two steps at a time, Lily bouncing on his hip. He pushed open the door to the boys' room and pointed his wand at whoever was attacking his children.

James and Albus were sitting cross legged on their bedroom floor, a game of exploding snap between them. Both boys looked up when Harry burst into the room.

"Hi, Dad," James said, confused as to why his father was pointing his wand at him. "What's wrong?"

"I thought I heard a scream?"

"Yeah, Al screamed when 'Splodin' Snap 'sploded. He's a cry-baby."

"I'm noooot," wailed Albus.

"Boys stop arguing, please. I'm sick of telling you this." Ginny had entered the room. She turned and looked at Harry after James crossed his arms angrily, bottom lip pouting.

"Why are you pointing your wand at them?" she asked turning to Harry.

"I thought… You said – where's the danger?" Harry spluttered. Ginny looked positively confused.

"Danger? You're turning into Mad-Eye."

"Why did you tell me to come home?"

Ginny's face broke into a grin. "I need you to watch the kids this afternoon. The Brazilian National Quidditch team are in Britain and they've agreed to give me an exclusive interview. This is a big deal for me – they've agreed to talk about the dragon fire scandal!"

"That's great, Gin," Harry said, leaning in to kiss her, ignoring the groans and fake retching noises James was making.

"Can you watch them? You have Friday afternoons free, right?"

"Yeah, of course."

The next half an hour passed without incident – possibly a record in the Potter household. James and Albus were happily playing dragon tamers, their favourite game since Charlie had last visited. Lily had fallen asleep lying across Harry's lap. He was feeling rather peaceful as he stroked Lily's hair and watched the rise and fall of her sleeping body.

As usual, the peace and tranquillity of the moment quickly disappeared with the arrival of a familiar Patronus in the form of a Jack Russell terrier.

"Harry, Jenkins has left his post. The forest is unguarded. We need you to assign someone new there. Richards or Taylor maybe – whoever his number two is. It's all on that board of yours." Ron's voice boomed from the mouth of the Jack Russell, waking Lily in the process. Lily began to cry.

Harry groaned. The enchanted board which alerted all members of the team to changes in their positions was in his office at Hogwarts. It had seemed genius at the time – the board operated in a similar way to the Marauder's Map by showing the location of each member of his team in Hogwarts. In addition, Harry could make changes to the scheduling and positions of his team using the board and they would be alerted. Not much help to him when he wasn't in his office. He had to act fast.

"Alright you lot, we're going to dad's office. Get your shoes on," Harry said, scooping up Lily.

"We're really going to Hogwarts?" James asked excitedly, his face fixed in an expression of shock.

"Only into my office for a few minutes. We'll Floo there. Come on." James and Albus immediately jumped up. James began whooping and Albus followed suit.

Flooing with children was always difficult, especially when he was outnumbered three to one. He made James and Albus wrap themselves around one leg each while he held Lily. He grabbed a handful of Floo powder.

"Alright on the count of three… One, two, three. Potter's Office, Hogwarts!" With a tight squeeze and a whoosh, Harry arrived into what would have been the living quarters of his office with his children in tow. James and Albus immediately began running around his office.

"I want you two to sit over there," he said gesturing towards the large couch next to the fireplace in the office. "If either of you misbehaves in any way I will be telling your mother and I will let her punish you however she wants." James and Albus nodded seriously and sat onto the couch. They weren't afraid of any punishment Harry would give, they knew he was too soft with them. Ginny however was a force to be reckoned with. She had learned how to strike fear into her children in a way Harry had only seen done by Mrs Weasley. Like mother, like daughter.

Confident in the knowledge that his children were afraid of their mother, Harry went from the living quarters into the main area of his office with Lily. He quickly made his way towards his planning board and took a look. As Ron had suspected, Taylor was Jenkins' number two. He quickly rearranged the board and cast the spell to alert his team. He sent a Patronus back to Ron to thank him and let him know the situation had been resolved.

Having left his two sons alone in the next room for no more than five minutes, Harry was eager to get back to them before the threat of their mother's wrath wore off. He was about to go into them and take them home when there was a knock at his office door.

Cursing under his breath, Harry attempted to put Lily down. As soon as he did so she began to cry. He quickly picked her back up, deciding that it was better to answer the door holding a child rather than having her scream in the background. The door knocked again and Harry rushed forward. He swung open the door to reveal Eleanor Long, an overly eager fifth year Ravenclaw.

"Professor Potter, I have some questions about the essay you assigned on – oh, is this a bad time?" Her eagerness had dissipated when as her eyes were drawn to the baby in Harry's arms. The last thing Harry needed now was students questioning him about essays. He hesitated before answering but was cut off by Eleanor launching into more questions.

"I also wanted to ask you about Patronus classes, as Ravenclaw prefect I have volunteered to organise the rota for our year. I want to talk to you about your availability so I can organise it quickly."

Harry looked at the girl's eager face and was reminded, not for the first time, of a young Hermione. It made it impossible for him to say no. Despite only taking the position to help with the Greyback case, he enjoyed being a teacher. He wanted his students to succeed and was happy that they would come to him outside of class hours with questions.

"Not a bad time, Eleanor," he said kindly, opening the door wider to allow her to step into his office. "We'll have to make it quick though, I'm in charge of my kids this afternoon so I only popped into my office briefly."

Eleanor nodded and walked into the office with a bounce in her step. "Your baby is so cute," she said cooing at Lily.

"This is Lily," he said as the baby gurgled back at Eleanor. "She'll be quiet while we speak, it's the other two we need to worry about." He glanced over at the back room in his office where he knew the boys were. While he couldn't see them, he could hear the murmurs of their voices – not raised voices and not silence so he was assured that, for the time being, they weren't causing trouble.

"Take a seat and let's get started."

Winter was beginning to set in across the Hogwarts grounds. Teddy had spent the last few hours of their Friday afternoon off hanging around the grounds with Fionn, Amina and Chloe. Chloe had begun to complain about the cold and they decided it was probably a good time to head towards the library to make a start on their weekend homework.

The entrance hall was busy, with many students walking in various destinations, making the most of their afternoon off. Amina and Chloe were talking animatedly about one of the Gryffindor chasers while Fionn muttered to Teddy about how they were spending too much time with girls. Teddy was laughing in agreement when he heard someone calling his name.

"TEDDY!"

All of the students walking through the entrance hall turned to look at the source of the squeals. Two small boys had barrelled towards Teddy and were wrapping their arms around his legs.

"James, Al! What are you doing here?" Teddy said in surprise. Most of the students around him had walked on but were still looking at him with interest. Fionn, Amina and Chloe stopped alongside Teddy and were looking at the two boys talking excitedly with amusement. "They're Harry's kids," he told them quickly.

"Mummy left and Daddy was minding us but he had to come to Hogwarts and we were being good but then we wanted to go and find Gryffindor tower but we didn't know the way and now we're lost but then we saw you and –"

"Does your Dad know where you are?" Teddy asked, cutting off James' babbled explanation. A guilty look spread across James' face as he gave Teddy a small smile.

"It was Al's idea too."

"It was not!" Albus said indignantly, tears welling in his big green eyes. "Jamie made me come but – but – we're – lost -" He began blubbering, unable to finish his sentence.

Teddy kneeled down and wrapped his arm around Albus in an attempt to cheer him up. "No need to worry, Al. You found me! Hey, you get to meet my friends now!" Teddy said in an attempt to distract him. "This is Fionn, Amina and Chloe."

Chloe bent down and opened her arms. "So nice to meet you boys!" Albus willingly hugged her. "We'll help you find your Dad." Albus nodded, still hugging Chloe.

"He likes you," Teddy said. Chloe smiled. "I'm used to being around kids."

"Well I'm not going back," James said grumpily, stamping his foot. "We didn't find Gryffindor."

"You can't get into Gryffindor tower, you're not even in Gryffindor," Teddy said attempting to reason with him. Unfortunately, reasoning with a five-year old never went down well.

"But I will be!"

"Well you don't know that yet."

"I do!"

"You don't."

"Do!"

"Ok, enough," Teddy said. He was falling into a silly brotherly argument the likes of which he often had with James. "We have to find your Dad, end of."

James pouted with his bottom lip stuck out. A glint appeared in his eye. "Do the nose first and then I'll go."

"Not now, Jamie," Teddy said glancing at his friends.

"Pweeease, Teddy," Albus said, tears gone from his face.

"I kind of want to see this nose too, Teddy," Fionn said with a smirk.

"Yeah, show us," Amina said joining in.

"Oh, alright then. But you have to promise that you'll come with me to find your Dad then." The two boys nodded eagerly.

Teddy screwed up his face and morphed his nose into a pig's snout. James and Albus cheered while his friends began hooting with laughter. He quickly changed his nose back to normal.

"Ready to go?"

"Teddy, I had no idea you could change your face too," Fionn said through peals of laughter.

"I told you I'm a metamorphmagus."

"How am I supposed to know what that is? I thought it was just hair."

"Never mind. Jamie, Al, let's get going." He grabbed James by the hand while Chloe held Albus' hand. Albus was chattering happily about dragons to Chloe who was reacting in mock-shock and feigning interest appropriately.

As they reached the second floor where Harry's office was located, they met him sprinting down the corridor holding Lily. He was looking very stressed and his hair was messier than usual.

"James! Albus!" Harry ran towards the boys and wrapped them both in a one armed hugged while holding Lily in the other arm. His look of relief quickly turned to anger.

"What in Merlin's name made you think it was a good idea to leave my office?" he said angrily. "I told you to stay there. Do you know how dangerous that was? You're lucky Teddy found you and not somebody else. I will be telling your mother and she can decide on the punishment."

"No, Daddy please don't tell her," James pleaded. Harry ignored him. He turned to Teddy and his friends.

"Thank you for bringing them here. Where did you find them?"

"They came up to me in entrance hall," Teddy explained. "Said they were looking for Gryffindor tower."

Harry shook his head. "I can't leave them alone for five minutes. Merlin knows what trouble they're going to get into when they're actually old enough to come here."

Harry brought Teddy and his friends back to his office with James, Albus and Lily. Harry gave them bottles of butterbeer. Amina and Chloe gushed over baby Lily while James was animatedly telling Fionn all about his plan to find Gryffindor tower while Albus tried to copy James' actions.

"I don't know what would have happened if they hadn't run into you, Ted," Harry said seriously.

Teddy shrugged. "There's not many kids running around the castle. Someone would have found them and brought them back to you."

"At least this gives me the opportunity to properly meet your friends," Harry said smiling towards them. "When you lot are in here, I'm not Professor Potter, I'm just Teddy's godfather Harry."

"That will take a bit of getting used to," Fionn said.

"How are you lot adjusting to Hogwarts? Teddy said you two are muggle born?"

Fionn and Chloe nodded. "Yeah it was a shock when I found out," Fionn said. "My parents had no idea magic existed and then they weren't too happy about me moving away for school, but they got used to the idea and now they think it's wicked. They think my brother and sister are magic now too."

"That's possible," Harry said. "It's likely that both of your parents had magical ancestors, however far back, and their combined genetics allowed for the magical abilities to be awakened in you."

"Huh, is that how it works?" Fionn asked, a strained expression on his face as he wrapped his head around it.

Harry shrugged. "My friend Hermione is muggle born and she tried explaining it to me. It's much more complicated than that but wizards don't typically care about genetics."

"They care about blood status though, don't they?" asked Chloe. Teddy looked at his friend. Chloe seemed rather serious. Was this something that she was concerned about? Harry looked at her appraisingly.

"Not anymore," he said firmly. "I assume you know that blood status was one of the reasons that Voldemort did what he did. Few people know that his own father was a muggle which is why he cared so much about it. The truth is, very few witches or wizards are truly pure-blood anymore. We'd die out if that was the case."

"Yeah, my dad's mum was a muggle, right Harry?" Teddy said.

Harry nodded. "And my mum was muggle-born."

Harry looked thoughtful for a moment. "Is someone giving you trouble, Chloe?" Harry asked suddenly concerned. "Hogwarts doesn't tolerate discrimination, so you can tell me."

Chloe shook her head. "I just heard that blood status is important, and I don't know my –" She stopped herself. "Nobody has said anything. I'm just curious."

Harry nodded but he did not look convinced.

"Harry, are you in there?" a voice called from the other room.

"Uncle Ron!" James yelled, running into the other room. Harry followed suit. He returned moments later with James in tow.

"Teddy, do you mind watching them for a few minutes? Ron needs to talk to me about a case."

"No problem," Teddy grinned, taking Lily from Harry.

James and Albus began chatting animatedly to Teddy and his friends. Teddy put Lily down but kept one eye on her. She has started walking and had a fondness for exploring places she shouldn't be. Within moments, Lily had made her way over to Harry's desk and had started pulling pieces of parchment down.

"Lily, stop!" Teddy ran and picked her up, Lily squirming in his arms as he did so. He was about to carry her back to the others when one of the pieces of parchment caught his eye.

Mr Potter,

I am writing to you to inform you of a recent encounter I had with escaped convict Fenrir Greyback. I do not wish to reveal myself, but I feel that I have information that is crucial to your investigated.

Greyback found me shortly after he escaped from Azkaban. We have crossed paths in the past as I spent some time underground with other werewolves during the war. It was the safest option for me at the time, but I have long since left them.

Greyback wanted to recruit me to his new army. He plans on creating an army of wolves that will overthrow the current Ministry. He claims he has found a way to create a race of super-werewolves through select breeding. He believes that any children born to wolves possess extra strength. I believe that he searched for me specifically because my wife and I once conceived but tragically died during her pregnancy. Greyback was not to know about their fate so he came in search of my child.

I hope that this letter will help you in your investigation. Above all, I hope it will help protect the young Lupin boy.

Yours in solitude,

T.R.

Teddy's hands were shaking when he finished the letter. What did it mean? Who was T.R? Was what he was saying the truth?

Teddy hastily carried Lily back to where his friends sat. As he did, Harry re-entered the room. Was he taking this letter seriously? Teddy had to trust that Harry was doing everything in his power to catch Greyback. He only wished that there was some way that he could help.

AN: This chapter serves as a bit of a filler and also a bit of fun with Harry's kids.

It's been a while since I've updated this story! Unfortunately life got in the way and I haven't had very much free time to work on writing.

Thank you to all who are following this story so far!

I really do appreciate reviews. It is slightly unmotivating when it seems like nobody is engaging with the story so please do review.

I am currently working on a prequel to this story from Harry and Andromeda's point of view. I don't want to start posting yet as it will give away some spoilers for this story but stay tuned!
