A Niffler through Time

Who?

"Hello? Who.Are.You?" Tina stated plainly with desperation seeping through. The eldest boy looked at them all in distress and the youngest brunette hissed
"John they're more likely to hurt us if we don't tell them who we are" The boy then took a deep breath and said
"What we're about to say is going to be pretty unbelievable b-but please-"
"Let us explain" Newts look-alike added. Theseus stowed away his wand and Newt replaced his in his holster.
"Explain then" Tina demanded
"We're from 1944 and are the next generation of Scamander and Kowalskis" The boy froze looking at the blatant air of disbelief in the room momentarily before continuing "I'm John Newton Scamander, I'm sixteen and I'm the oldest out of well- all of us"
"S-Scamander?" Newt heard his brother stutter but in his mind, he was trying to figure out whether this was true. They were wearing clothes that Newt wouldn't describe as currently in fashion and were in possession of both a niffler and a time turner. The boy who was startlingly familiar to Newt spoke next
Theseus must have three children. I'm an uncle to THREE children!
"I'm Nicholas Jacob Scamander and I'm thirteen and uh-"
"The reason we're in this mess" The girl with the plait finished looking thoroughly unimpressed.
"Perhaps but in fairness, we were all meant to double-check the lock on the niffler nest" Nicholas murmured under his breath. The girl rolled her eyes but did look slightly guilty as she introduced herself
"I'm Elizabeth Linnet Scamander and I'm eleven" she began to nervously fiddle with her plait as she joined her brothers, who were currently standing awkwardly against the sofa.
"So-um we're the Scamanders"
I have a niece and two nephews
"Oh, my Gawd Uncle Newt the three of them aren't your nieces and nephews! Well, John is but Nick and Liz are your children!"The brunette exclaimed exasperatedly making both Nicholas and Elizabeth look slightly insulted
"I love Uncle Theseus but I wouldn't lose the creatures for anything" Elizabeth commented sharply.
So who on Earth?
The brunette giggled again and Newt asked
"You're a legilimens aren't you?"
"Yep, and the oldest Kowalski!'' Jacob made a shocked spluttering noise behind him but she just smiled at him and carried on "I'm Molly Esther Kowalski. I was going to be Molly Porpentina but Auntie Teenie forbade it. I'm fifteen!" She seemed overly excited at the whole interaction. The final child to introduce herself stepped forward
"And I'm the youngest Kowalski, Penelope Marie and I'm thirteen"
"Two children, I have two children" Jacob mumbled in surprise
"So do I apparently" Newt murmured back. As everyone remained in stunned silence a small bowtruckle popped its head out of Elizabeth's top pocket and began to chirp loudly. She was in quite a lot of discomfort and to his immense surprise they began to reply
"Yes-We're sorry but you were meant to stay with your mum and dad on the tree" Nicholas sighed to more indignant chirping. Elizabeth then shook her head and replied
"Okay fine, Pick was in dad's pocket and Hope was in mums but that's beside the point"
"You two speak Bowtruckle?" Newt blurted in surprise. They both scoffed in unison and Elizabeth answered
"Honestly Dad we've been out in the menagerie since we were born"
"Plus Pickett was in your pocket around 90% of the time up until I was eight" Nicholas added. Newt knew he was staring but it was a remarkable shock to see HIS children stood there understanding Bowtruckle.

"Amazing, can we ask about your mother's?" Theseus interrupted, looking apprehensive about the answer. The children turned to each other and John asked
"We could tell them straight or we could have some fun with this!"
"Well I vote fun" Molly declared and her sister Penny nodded excitedly.
"Definitely," Nicholas and Elizabeth said as well, much to Newt's displeasure. John moved back to his original position with a wide grin.
"My Mums not in this room but Uncle Newt knows her very well. I also have an estranged Uncle called Yusuf but he's quite intense and he hasn't got a case full of magical creatures" Theseus' face broke out into a mirrored grin and he exclaimed
"Leta! Leta. Sh-She- we get her back?" His eyes were wet but alight with excitement
"Yeah" John confirmed with a smile and Theseus let out a loud sigh of relief, as did most of the room.
"We'll go next because Uncle Newt has zero clue" Molly began clutching Penny's hand in excitement
"I think ours is pretty obvious based on our magic, baking skills and Molly's gift" Penny explained
"It runs in the family much to everyone's dismay" Molly added
"Christmas is difficult because you can't keep presents secret with both Molly and Auntie Queenie" John huffed good-naturedly
"Oh, you love it" Molly teased back. Elizabeth just rolled her eyes and said
"Anyways can we go now?" There was some nodding and everyone turned to look at Newt making him fidget nervously. Marriage hadn't ever crossed his mind let alone children. He always thought it must be a nice concept but he hadn't really found anyone he'd ever want that with.
You did in New York
Ignoring his infuriating inner monologue, and the poorly repressed giggle coming from Molly he looked at the children that looked so startlingly like him it was scary expectantly.
"Dad's favourite story is the story of how they met mostly because so much happened. We have it memorised" Elizabeth began with a small smile
"It's still funny that Dad was arrested by Mum because he let a Niffler loose in a bank" Newt inhaled sharply and froze and he felt Tina do the same beside him. There was no mistaking which story they were talking about. It was a rather memorable occasion.
I marry Tina? We have children? That's why Elizabeth looked so similar; she looks more like Tina! How on Earth do I propose? Oh, Merlin how am I going to look her in the eye now?
"Mum, Dad calm down"
"I am calm!" Newt and Tina replied at the same time much to their embarrassment and the children dissolved into peals of laughter.
"Oh, honestly you two are actually surprised? You've been dancing around the subject since yous got back from Paris" Jacob
"It's been infuriating" Theseus continued
"Can we please focus on the time-travelling children?"Tina sighed but her grin couldn't be restrained as she stared at her feet
"So you got here via Time Turner? How did you even come to possess one of those let alone break it?" Theseus questioned and the entire group turned to Nicholas who was still holding the Niffler in one hand and the necklace in the other. He gave a bashful grimace before looking down at his feet as the rest gave nervous chuckles.
"I think an explanation is required. Now."Tina stated and a flitter of fear flew across everyone's faces.
"It's a long story" Elizabeth murmured, now also looking at her shoes.
"So get explaining then"

This is a major side project so it's only going to be updated once in a blue moon but here's chapter 2 :)
