The distant roars of the Indominus Rex made the leaves on the trees around them shake, and every so often Ellis could've sworn she felt the ground shudder beneath her booted feet, impact tremors, she figured, sent through the earth each time the incredibly large animal took a step. Deciding not to voice her theories about the weight of the animal that was undoubtedly ravaging its way through a herd of unsuspecting herbivores somewhere on the other side of the island Ellis ushered both of the boys forwards. She had only a mild notion of where it was she was headed, but her outward appearance gave no indication of her inner worries, she looked like she had the entire situation totally under control, despite the fact that she absolutely did not.

"It's more like millions of years." Gray mused, making sure to keep his voice quiet as not to attract any unwanted attention from any of the islands inhabitants.

"What are you talking about?" Zach snapped, a little way ahead of both his younger brother and Ellis.

Ellis frowned at Zach's tone of voice, and the way a smirk danced upon his lips when he turned to look at his brother, she hadn't grown up with any siblings but had she done she would have hoped to get along with them better than the Mitchell boys seem to.

"This claw," Gray held up the raptor claw that Ellis had handed him when they first met. "You said that it was thousands of years old, but it's really millions."

She smiled, giving a slight nod as she clambered over her second fallen tree of the day. Zach turned to offer her his hand, to aid her over the trunk of the tree, Ellis merely raised a brow point blank refusing his offer and making her own way over. She didn't wince when a shooting pain ran from the wound in her arm up to her shoulder, instead she turned her attention to Gray. "You know about dinosaurs?" She asked.

"He doesn't shut up about them, it's pretty annoying actually. His entire bedroom is covered with them." Zach commented dryly.

Gray, who had been making a conscious effort to stay as close to Ellis' side as he could without ever actually touching her, blushed and his gaze momentarily flickered to the leaf covered ground. Ellis, on the other hand, was beaming down at the short boy with his wet curls and adorable embarrassment. She was, however, quickly growing tired of Zach Mitchell and his attitude, she was the daughter of Alan Grant after all – and despite her paleontological breakthrough in the nurturing habits of dinosaurs, she had little to no remotely nurturing instincts herself. All Ellis had to do was get these kids off the island alive, then she never had to see them again, but if she could pass the time by talking shop with the youngest one then she would.

"Well," Ellis continued, readjusting the rifle on her shoulder before continuing. "I love dinosaurs; they're all I've ever known. My dad's a palaeontologist, and I guess you could say that I am too, though Asset Behavioural Analyst is my official title."

"Is your dad Alan Grant?" Grays voice was still quiet and Ellis didn't know if he was doing it to avoid attracting the attention of the Indominus Rex – that could no doubt smell them from miles away so really his attempts to remain undetected were in vain – or if he was simply trying to avoid being chastised yet again by his brother.

"Yeah, you heard of him?"

"I've read all his books, even the ones after he came to the island."

"Even those..." Ellis mused, raising her brows in mock surprise. It was no secret that Alan Grant's visit to the original Jurassic Park changed him, or at least his opinions on dinosaurs. Eric Kirby had put it perfectly; Alan had 'liked dinosaurs' before he'd visited Jurassic Park. The books he released after his return from the island were purely scientific, made up entirely of research; there wasn't an ounce of feeling in them, which was why so many people preferred his earlier works.

"So Ellis..." Zach drawled, not bothering to look over his shoulder at the girl he was addressing, instead choosing to keep his gaze forward. He thought it made him look disinterested, alluring even, but all of his attempts to be completely irresistible flew straight over Ellis' head. "Not to sound rude or anything but do you actually have any idea where we're going?"

"Nope." Ellis mused, making both boys stop dead in their tracks. Gray looked up at her through large worried eyes and Zach turned to actually face her, his cool guy façade faltering and a young, scared boy shining through the cracks.

"Oh god, we're going to die. We're going to get eaten and die out here oh my god." Gray was mumbling incoherently now, pacing back and forth in the small clearing they found themselves in. He only stopped when Ellis physically grabbed him by the shoulders and gave him a light shake.

"Hey, hey!" She whisper yelled. "You are not going to get eaten, I'm not going to let anything happen to you okay?"

"That's what Zara promised Aunt Claire she'd do as well; forgive me for not believing another girl who promises to protect me on an island of monsters." Zach Mitchell scoffed, rubbing the back of his neck as he spoke.

Ellis' eyebrows knitted together into a frown, one that caused wrinkles to form across her forehead and her entire face appear older than she actually was. "Well forgive me if I'm wrong but you are the one who ditched Zara, not the other way around. If you'd both actually done what you were told then you wouldn't be in this mess and I wouldn't be recreating history by getting two kids off an island they probably shouldn't even be on in the first place!"

Zach opened and closed his mouth multiple times as he attempted to come up with the perfect protest, but was beaten to it by Gray who had tears running down his plump cheeks. "It was Zach's idea to run away!" He sobbed; Ellis automatically released his shoulders from her – perhaps too tight – grasp and instead dropped down to her knees in front of him. It was becoming increasingly clear to the brunette that these two boys were only kids, scared kids that wanted nothing more than to go home and as much as it pained her to admit it she should probably start being a little nicer to them. Raising a hand she wiped a tear from his cheek and smiled softly at him tilting her head ever so slightly to the side before she spoke.

"Look," She said, addressing both of the boys now. "I'm sorry for yelling, it's not either of your faults that we're here. If it's anyone's it's Dr Wu's and I should probably have called that months ago..." Ellis sighed as she got to her feet once more, taking Gray's smaller hand in her own and giving it a light squeeze. "...and I do know where I'm going, sort of. See that over there?" She pointed through the trees; both boys moved to stand directly beside her and squinted in the direction she was pointing at.

"No" Zach said simply.

"The river?" Gray piped up, Ellis nodded.

"That river feeds into the Mosasaur habitat right in the middle of the park, follow the river and we get back to Main Street. That's my thoughts anyways; I just hope we're following it in the right direction."

"Oh really?" Zach spoke again. "Because I was hoping to get further into the island, you know where the real danger is." Ellis whipped her head round to look at him, ready the glare a hole right through his head but when she was met with his grinning face she couldn't help but laugh at his dire attempt at a joke, and simply shook her head in response. Gray – who still clung tightly to her hand – sniggered quietly.

The three of them didn't argue after that, in fact they ambled for another ten minutes or so quite happily through the trees. Gray, lured into a false sense of security by the fact that nothing had tried to eat him for well over half an hour, let go of Ellis' hand and ran a little way ahead of his brother and his saviour to explore their surroundings – Ellis had shouted ahead telling him to always stay within view of her, and Gray had smiled and given a thumbs up in response. They were part way through Ellis' turn at picking something in a game of eye-spy when the reality of their situation came crashing down on them like a tonne of bricks.

Somewhere, a lot closer than Ellis was entirely comfortable with, the Indominus Rex roared. The sound was terrifyingly loud and for a moment Ellis froze in the spot where she stood, remembering the dinosaur and how close it had been to ending her life just that afternoon. She remembered the stench of rotting flesh, the pain in her arm, the feel of the I-Rex's breath on her skin and the crippling fear in the notion that this was it, she was going to die. It was Zach that pulled her out of her own dark thoughts when he tugged on the sleeve of her flannel shirt, his other hand wrapped protectively around his younger brother who had run back towards them the moment he'd heard the Indominus.

"What do we do?" Zach whispered, flinching when the Indominus roared again, even closer this time.

Ellis blinked rapidly for a moment, her breath hitching in her throat as she looked down at the two helpless children, kids that she was supposed to save, kids that if her dad were here would probably already be tucked up safely at home by now. It took her a couple of milliseconds to snap herself out of it but eventually the brunette leaned down towards them, her expression serious and her voice even more so. "Okay boys...I'm gonna need you to run. We need to put as much distance between us and this thing as we can, okay, can you do that for me?"

Zach nodded quickly, turning towards his brother and giving the younger boy a slight shove in the direction that they'd all been heading. "Okay lets-"

"I can't..." Gray whimpered.

"You can!" Zach's words of encouragement seemed to be enough to kick his brother into gear and Gray swallowed hard before nodding. The younger boy turned on his heel and made off further into the dense foliage that surrounded him, Zach no more than a pace behind him. Ellis secured the rifle on her shoulder and the radio on the belt of her shorts before she too ran after the boys.

They ran as fast as they could, undeterred by the branches that scratched at their skin or the burning sensations that ran up their legs, they ran through the pain in their lungs that cried out in over exertion, begging for just a moment to catch a breath, to take in some air. Occasionally Gray would fall behind and Ellis would double back, grab him by the arm and drag him forwards alongside her, her injured arm was throbbing and she was almost certain that the wound she'd sustained earlier had opened itself up again, she could feel fresh blood trickling down her arm, making her flannel shirt stick to her skin once again but she ignored all that, she ignored it all and she ran as hard and as fast as she could, all the while keeping a tight hold on Gray.

She made a conscious effort to always keep the river on her left hand side, and to ensure that the boys did too. If they had any hope of getting out of this, following the river was their best bet and even running for her life she couldn't afford to lose sight of the rushing water. Getting turned around in the Isla Nublar jungle would be akin to signing her own death certificate, and she'd already promised the boys that they weren't going to die today – Ellis Grant never broke a promise.

The trio slowed and eventually stopped for two reasons, the first and most prominent being that the Indominus Rex did not appear to be chasing them, the impact tremors that surged through the leaf covered ground were becoming less and less frequent as each minute passed by and Ellis was pretty sure she could hear the chirps of birds and smaller animals in the trees that surrounded them – something that would absolutely not be the case is an apex predator was anywhere in the vicinity. The second, and perhaps the more interesting of the two, was the dilapidated building that they happened upon.

It was surrounded by trees, some which appeared to be growing through the very structure of the building that it was clear had once been a very impressive sight to behold. Opposite it the river widened into what Ellis could only describe as a large pond, one that was obviously manmade and that had once been well kept with a water feature taking pride of place in the middle of it. Moss, dirt and other flora covered the walls of the building, and thick vines had grown across the large ornate doors. Ellis dropped Gray's hand from her own and walked up the steps towards the once lavish entrance of the building, leaving the boys at the bottom staring up at her.

"What is this place?" Zach spoke, more of a thought to himself than a question but Ellis answered it nonetheless.

"The visitor centre." She read the words that were carved into the stone slab above the door, just below an intricate carving of the skull of a Tyrannosaurus Rex. She spoke again as she pulled on the vines that covered the doors, restricting them access to the building. "I think it's part of the old park, my dad told me about this place once when he'd had a bit too much to drink. He almost died in here, surrounded by raptors..."

Gray looked positively horrified at the bottom of the steps. "Velociraptors?"

Taking a moment away from clearing the debris Ellis glanced back towards the boys and offered them a grin. "They were all rounded up long before Jurassic World ever opened, don't worry, they're not still in there. Now if I could just..." She rammed her good shoulder against the door in an attempt to open it. The door creaked in response but otherwise did not move. "Open this door, we could get a look inside, maybe call for help?"

"Uh, Ellis?" Zach mumbled.

"What?" The brunette huffed as she charged the door once more.

"As much as I'm enjoying watching you try to open a door why don't we just..." His voice trailed off into silence and Ellis' dark eyes followed his pointing finger. He was pointing at a gaping hole in the side of the building, around it fallen scaffolding lay on the ground but otherwise it was a completely clear entrance into the visitors centre.

Zach smirked and Ellis rolled her eyes, hurrying down the steps once more and climbing over the fallen scaffolding before finally stepping into the large entrance hall of the building. "Well come on then!"

It didn't take the boys long to weigh up the pros and cons of inside versus outside, outside they were less likely to die when the building inevitably caved in on itself, but they were also a lot more likely to be eaten out there in the open. Inside provided them with shelter from the elements and the very animal they had just been running from, but the structure of the old visitors centre did look questionable at best - it was the decision that being crushed to death was a more desirable way to go than being eaten that saw the boys climbing over the fallen scaffolding and following Ellis into the entrance hall.

"Is that what I think it is?" Zach asked, pointing towards what appeared to be the bones of a dinosaur, and a very big one at that.

"It's a tyrannosaurus..." Gray breathed out, he'd been to enough museums and read enough books to recognise the skeleton of a tyrannosaurus rex when he saw one.

In the time it had taken the boys to wander in after her, Ellis had already headed further into the building and was currently crouched down over the very bones Zach was pointing to from the other side of the room. She picked one of the smaller metatarsals up and turned it over in her hands, surprised by the weight of it, or the lack thereof. "It's not real." She said, her tone laced with disappointment as she tossed the plaster cast bone to the ground. "Must have just been for decoration...can either of you see a light switch?"

Picking something up off the ground Zach turned it over in his hands. It was the remnants of a banner that had once read 'when dinosaurs ruled the earth'. "Gray have you still got those matches in your nerd purse?"

Gray frowned, "It's not a nerd purse it's a fanny pack." He muttered defiantly as he rifled through the small black bag that had been tied around his waist since the moment they left their parents at the airport back in America. When he pulled out the small pack of matches a smug smile flourished upon his soft features and he threw the matchbox in his brother's direction.

Lighting a match took a few attempts, they were still damp from the boys trip over the waterfall earlier that afternoon, but eventually Zach managed to get one lit long enough to ignite the banner that he'd tied around one of the leg bones of the plaster cast t-rex. Part of Ellis wanted to snatch the makeshift torch from him and stamp it out, that was a piece of history his was burning, something that her father had probably rolled his eyes at when he'd visited the island all those years ago and it was also something that the Indominus Rex would almost definitely be able to smell burning from miles away. Another part of her, however, was thankful for the light in the darkness, and much too intrigued by the building they currently found themselves in to be afraid – so she did nothing except follow the boys as they moved further into the visitors centre.

They wandered through a multitude of different rooms, each one lit up by the eerie flickering glow of the torch that Zach held above his head and each one completely overrun by the elements. Vines covered the once carpeted floors, grew up over desks and through the arms of chairs. The hairs on Ellis' arms stood on end as she walked through each room of the building that was essentially a ghost town. The abandoned laboratory was the room she found most interesting, because everything was exactly where it had been left twenty two years ago. A half drank cup of god only knows what lay untouched and moulded on one of the work benches, discarded latex gloves filled the trashcans that hadn't been emptied in years and there was even unfinished research strewn here and there. She picked up one clipboard and blew away the dust and debris, she instantly recognised the handwriting on the yellowed paper as that of Dr Henry Wu – she'd read enough of his reports to see her through to the end of her life and had involuntarily memorised his penmanship perhaps only a few weeks after accepting her new position at Jurassic World.

"Look at this!" Gray chirped from the other side of the room, Ellis took one last look at Wu's unfinished notes before placing the clipboard back down where she'd found it and moving across the laboratory to where Gray stood over an incubator. Standing on his tiptoes so that he could get a better reach, Gray leaned as far as he could into the incubator and grasped for what it was he had called her over to see. When he finally caught hold of it he pulled it gingerly from the spot it had called its home for over twenty years and held it up for Ellis to see. "It's an egg." He stated, despite it being completely obvious.

Stretching across him Ellis picked up another shell and inspected it in silent fascination. She'd never seen a dinosaur egg before, or rather an ostrich egg substituting as a dinosaur egg and an odd sensation of honour washed over her – this was where it had all began, Jurassic Park, Jurassic World, John Hammonds vision. Only a handful of people had seen this place, and she was one of them. "There's some notes over there," she explained, nodding towards the clipboard she'd put back down "that say they were growing velociraptors in here..."

"How?"
