Hey, so I've written some more. I definitely have some kind of plan as to where this is going. I hope that you are still enjoying it, and thank you again for all your kind reviews. Let me know what you think :)

Tina stepped into the case and began to descend the rickety ladder, keeping her eyes trained on the wobbly Newt above her. She hit the wooden floor of the hut, and took a step back, anxious to assist if he needed it.

Newt came down slowly, concentrating on each step and trying to ignore the lancing pain in his chest, he was spurred on by the sporadic roars issuing from below. When he made it down he had to take a second to catch his breath. Leaning against a wall, he looked at Tina's worried face, and gave her what he hoped was a reassuring smile.

"Let's go," he breathed, signalling for her to take the lead. They made their way out onto the great plains of Newt's case, following the booming cries of the erumpent. The sight that greeted Tina and Newt when they reached the clearing, caused them to pause for a second.
Queenie was standing in front of a frankly terrified Jacob, as the female erumpent relentlessly charged at her shield. Rarely flustered, Queenie was bright red and panting as she struggled to repel the desperate beast.

Tina wanted to call out to her younger sister, but feared breaking Queenie's concentration. So she and Newt slowly picked their way across the grass, edging closer to the trapped pair. When he deemed they were close enough, Newt stopped, taking a deep breath to steel himself, he stepped forward.

From Jacob's and Queenie's perspective he appeared from nowhere. Pale and sweating, with dark rings around his eyes, Newt nevertheless stood tall and confident. Wand in hand he strode determinedly towards the enamoured beast.

"Enough of this silliness," he said firmly, as he crossed into her eyeline. The erumpent paused at the sight of her lanky protetor, torn between him and the source of her affection.

"Come on now Beatrix.." he murmured, maintaining eye contact as he walked towards her, arms outspread, in an attempt to appear nonthreatening. No one dared to even breathe as Beatrix surveyed him, debating her options. Her eyes flicked towards Jacob, she tossed her head and narrowed them, mind made up.

"Dammit!" Newt cursed to himself, as she prepared to charge again. Directly in her pathway, his wiry frame was taut and ready for action, but as his friends watched on in disbelief, Newt closed his eyes. Tapping quickly into his centre, he connected to the ever present, and complex web of magic that encompassed the case. From here, he could sense the position of every creature and habitat right down to a single blade of grass. Without opening his eyes or uttering a sound, Newt started creating an intricate pattern of spell work. The others watched on with awe, as thick vines surged up from the ground, encircling the erumpent before she could charge.

Beatrix struggled as they encased her, wrapping tightly around her legs and torso, until movement became impossible. She let out a distressed trumpet, but after a few minutes of thrashing, seemed to realise resistance was futile.

Newt sensed her calm, but he still let out a sigh of relief when he saw her trussed up like a turkey and his friends safe. Still his work wasn't done, and as he walk to face Beatrix, he confidently brought his hand up, and carefully caressed her bulbous nose.

"There we are girl, that's enough of that," he said fondly, and the erumpent let out a gentle warbling as he tickled a sweet spot.

Her bindings seemed to sense her mood, as the vines slowly loosened and slid from her body, back into the loamy soil. Newt kept petting her snout, talking softly to her until just a harness was left around her muzzle. His attention didn't waver from her for a second, as he led Beatrix away from his friends back towards her habitat. Once she was safely placed back where she belonged, Newt again connected to the basal magic of the case. Manipulating the structures in within it, he triggered a powerful shielding charm, that created a barrier between the erumpent and the humans, restricting her to her enclosure until the area was clear.

With Beatrix secure, Newt turned and began slowly making his way back up to the rest of the group. However the adrenaline that had been fueling him quickly began to dissipate, now that the threat had past. Nearly halfway to them he suddenly stopped, going from standing tall to sagging on his knees in just a matter of seconds.

The trio, who had been captivated by Newt's capture of the erumpent, rushed across the grass towards his stricken form. Tina reached him first, with the others just behind, she crashed to her knees in front of him, her cool hands gently taking Newt's clammy face. He was burning up, swaying as tremors wracked his slight frame, Newt was struggling to keep himself upright.

"Newt, Newt...can you hear me," she said urgently, with a sense of deja vu. His clouded eyes blinked slowly at her, barely registering her presence.

"I..just.." he attempted to explain, her face fading in and out, as darkness threatened to claim him.

"Sleep.." he managed before it overcame him.

They watched in horror as Newt's face paled several shades, his eyes rolling into the back of his head, before he slumped forward into Tina's arms.
