A/N: I'm changing the timeline of when Harry and Tonks meet for the first time from the start of Harry's Fifth year to the start of his fourth year as to a young Teddy this was where Harry needed Tonks and him the most and where 'in Teddy's young and limited opinion' some people showed their true colours. Also I'll be using Latin words for spells throughout the story.

Chapter One – Adventure Begins
12, Grimmauld Place – 2003
Little Teddy Lupin-Potter sat in his room at no. 12 Grimmauld Place, playing with his stuffed animals and toy broom. That was until he heard the raised voices of his godfather now blood-adopted father Harry Potter and Aunt Ginny Weasley through the walls. Kreacher popped in to check on his young master, as was his orders from 'Master Harry' when Harry and Ginny had their shouting matches.
"Don't yous worry young master, Master Harry will be fine."
"Why do they yell all the time aunt Ginny comes over, 'reacher?"
"It's not for yous to know that young master."
"I want daddy to be happy, why can't he be with mummy, 'reacher?"
Kreacher had at first been against having the son of the werewolf known as Remus in the house, but over time grew to care for the little guy as Teddy showed no signs of Lycanthropy that his birth father was cursed with by the nightmarish creature known as Fenrir Greyback. But he did show the trademark signs of Metamorphmagus like his mother, Nymphadora Tonks nee Lupin.
"He is not just my godson anymore Ginny!"
"What!"
"I adopted Teddy okay! As in blood-adopted!"
"You what! Harry, Teddy is half werewolf and could be dangerous!"
"Teddy has shown no signs of the curse, and he's only got his grandmother and me."
They were closer to Teddy's room now, Kreacher moved to stand between the door and the young boy waiting. Heavy and angry sounding footsteps drew closer, Teddy and Kreacher tensed up.
"Can't you just for one night focus on me, your girlfriend!"
"So now you're my girlfriend again!"
"What does that mean? We've been dating since the battle of Hogwarts ended."
The two young adults were now right outside Teddy's door and still yelling at each other, Teddy grabbed hold of Kreacher.
"'reacher, I don't like aunt Ginny."
"Kreacher never liked the red-haired ones, save a few."
"I wish Daddy and Mummy were together."
"Kreacher knows a way, Great Master Arcturus had many things."
At the house elf's words Teddy sat up, green eyes meant bloodshot blue as the door flew open revealing an angry Harry Potter and a red-faced Ginny Weasley.
"Choose Harry James Potter, me your Girlfriend and future wife or the son of your dead friends!"
Harry and Kreacher stood there stock still at the demand, Ginny knew how much Remus and Tonks meant to Harry. And Harry was not just Teddy's godfather or blood adopted father but also family through the Black family tree with Harry's grandmother, Euphemia Dorea Potter nee Black.
"Well, it's not a hard decision then, my choice is Teddy."
Ginny was truly shocked at his words, Harry Potter, the man of her dreams to be her future husband for so long, had chosen a small child over her. The fiery red-head of Gryffindor quickly changed tactics, but not quick enough for Kreacher to catch it.
"I-I'm sorry that was wrong, it just feeling like you don't want to spend time with me."
Ginny was now trying her innocent schoolgirl approach, hoping it would defuse Harry into changing his mind. Harry sighed letting out a breath, he knew he couldn't stay mad at Ginny for long after everything they went through during the war with Riddle. To Harry family was everything, Teddy, Andromeda, Kreacher, Buckbeak and the Weasleys were the only family he had in the world.
"I know Gin. And I'm sorry that I haven't been spending time with you as much as I should but between work at the ministry, looking after Teddy and looking after two Most Ancient and Most Noble Houses I haven't had the time to even look after myself. It's only thanks to Kreacher here that I'm still standing half the time."
"Master Harry is too hard on himself. Kreacher is honoured to be yous house-elf."
"Thanks, Kreacher."
"That's why I wanted you to spend some time away with me. It would give you the needed time to relax and clear your head. Please Harry think about it, I'll come back later after dinner okay."
Ginny closed the gap between her and Harry and kissed his cheek, as she turned to leave Ginny glared at the small child that in her private opinion 'was standing in her way' of getting everything she wanted. Again Kreacher noticed this and raised a protective arm in front of the child while narrowing his eyes at the red-head.
"Yeah okay Gin, see ya."
Later that night after Teddy and Harry had dinner, Ginny returned as promised and had with her some of Harry's favourite foods foremost among them were the Treacle tart. The Elf was glaring from the doorway of the lounge room where Harry and Ginny were sitting and enjoying the deserts. Kreacher's eyes were focused heavily on Master Harry's face as he became a little pale and sickly looking, known trademarks of the 'evil in Kreacher's opinion' love potion called Amortentia.
"Kreacher not like this, Kreacher fix."
Popping upstairs to Teddy's room where Teddy was sleeping soundly, not wanting to wake the young master but knowing that he must stop the red-head's plans Kreacher shook Teddy awake.
"'reacher, what's happen'?"
"Young Master must come with Kreacher."
Kreacher helped Teddy out of bed and dressed him in his best clothes, before popping out of the room. They reappeared in a room that Teddy had never seen before, it had two walls lined books cases that made Teddy think of Aunt Hermione as well as an old looking desk all of which were covered in a heavy layer of dust.
"Wh-Where are we?"
"Master Arcturus' private study."
Teddy looked around while Kreacher moved to the desk, climbing up and onto the chair, Kreacher searched while quietly saying 'Where is it?'. Teddy in the meantime walked up to a curtain that sat in-between two bookcases and pulled on the cord.
"Who in Merlin's bloody name opened my curtains?"
The aged Elf bolted upright that the sound of Arcturus' voice, having remembered it when he was a young house elf.
"Who are you?"
"My name is Teddy and I am five 'ears old."
"And do you have a last name, Teddy?"
"Lupin-Potter, Teddy Lupin-Potter."
"Lupin-Potter? Well, I know of the Potters, my cousin Dorea became one. As for the Lupin, I knew of a Lyall Lupin. Any relation to either?"
"My daddy is Harry James Potter."
"Well I can see the trademark Potter hair, Fleamont had it as well. And who is that standing on my chair?"
"I's Kreacher, Master Arcturus. I's helping young Master in finding your treasure."
"My treasure? What do you mean?"
"The Treasure that helps yous move through time."
"You mean the Sickle of Cronus, Why?"
"Young Master wishes to see Master Harry and Mistress Tonks together."
"And does Young Master Teddy know the price for using said item?"
"No."
"Well take a seat Teddy and I'll tell you."
Kreacher helped Teddy into the chair as they both sat there, ready to hear all from the painting of the old Head of House Black. Arcturus informed them first that the Sickle came from Greece many years ago when he was in his seventh year at Hogwarts, his father Sirius Black the second had paid a large sum of galleons for it in the hopes that it might make the Black family rich and powerful but couldn't get it to work. Over the years Arcturus secretly studied the item as did his father until his death, where Arcturus hid it in his private study away from the rest of the family. It wasn't until the birth of his grandson, Sirius Black the third was born that he, at last, unlocked its purpose.
"He was daddy's godfather or dogfather as he called him."
"Yes I know, I made Sirius my heir and knew of his animagus form."
"What's an animassus?"
Arcturus chuckled at the misspelled word.
"An Animagus is a wizard or witch that can transform into an animal, and takes a lot of power and time to learn and master. Any way back to the Sickle, it wasn't until Sirius' birth that I discovered how to use it. But in doing so would have to pay a heavy price."
"What price Master Arcturus?" Kreacher asked.
"To use the Sickle of Cronus Kreacher, means that you can never return. The journey through time is one way, and it uses blood to activate. After unearthing this knowledge I hid the Sickle under a powerful cloaking spell. If you truly mean to travel back in time, I will reveal the Sickle. But only under one condition."
"What is that?" Teddy asked innocently.
"That my young friend is for Kreacher to destroy it, by smashing against the case that houses it. For if it were to fall into the wrong hands it could be devastating. So I want your word Kreacher, that once young Teddy here is gone you are to destroy that item no matter what."
"Kreacher understands Master."
"Good now to the revealing spell. Peculiari Revelare." Once Arcturus said the words of the spell, a glass case appeared under his painting with the Sickle of Cronus inside. "Patentibus."
With a click the case opened allowing Kreacher to reach in and take up the sickle, holding it with both hands before Teddy. Who looked up at Arcturus.
"Now Teddy, here is the tricky part. You must think of the time period you wish to travel to with all your magical might, heart and soul, once you have it and can not only see it but feel everything about it within side you then and only then must you touch the point of the blade."
"O-tay."
Teddy thought of the time he wished to go to, thinking of all the stories that Harry had told him about. There was daddy's first year, but daddy was only eleven and too young to be a daddy. There was his second year, but again daddy was too young and so was mummy. That brought Teddy to Harry's third year at Hogwarts, more importantly to the end and before the start of daddy's Fourth year. The year of the Tri-Wizard Tournament and Tom's return, once Teddy had sunk himself in the details of the year he just had to think of the date he wanted to go to.
Little Teddy remembered that the Weasleys had taken Daddy to the Quidditch World Cup, so Teddy focused on arriving a couple of days before his daddy got the invitation from the Weasleys.
"Have you got the date and time you want to travel to?"
"Yep."
"Good. Remember once you arrive, the timeline of events will change to create a whole new reality. So I'm just making sure that you understand that this is a one-way trip. Once you use the Sickle of Cronus and Kreacher destroys it, it will no longer exist in any timeline past, present or future as it is truly unique. Do you understand this?"
"Yep."
"Okay. Kreacher you may begin."
Kreacher edges the tip of the Sickle closer and closer to Teddy's tiny outstretched hand, his mind split in half. One half hoping that he does travel back and succusses as it would restore not just the House of Black but the House of Potter as well to their original standing within the magical communities. While the other half fears for the Young Master as time travel is both dangerous and unknown to anyone, Magical or not.
The moment Teddy's index finger connects with the green rune-covered metal tip of the blade, a bright white light flooded the room blinding all. A second passed before the room returned to normal minus one people, Teddy Potter-Black.
"Now Kreacher! Smash it against the case!"
With all his strength Kreacher slammed the Sickle hard against the rune-covered metal edges of the glass case, and again the room was bathed in white light before the pieces of the broken item disappeared from all existence.
