Chapter 5.

Jack let his snowy head rest on the closed door trying clam himself. This might have been a mistake if Elsa really had just attacked Hiccup would sealing them in a room together be the wisest move? He really didn't know, but what he did know was he felt drawn to the small freckled teen in a way he'd never felt before. It was like there was a thin tread connecting them it was fragile, only just beginning to form and now Elsa had caused it to fray. Hiccup was beyond terrified he could see it written across his face, in the way he was standing across the room clutching his left arm to his chest trebling uncontrollably and it hit Jack like a kick to the gut. He knew logically his older twin would never hurt someone without good reason. He hoped she'd just gotten carried away that it was a misunderstanding or an accident. Lifting his head he turned towards the other two occupants of the room. His heart sank at the scene. Hiccup was cowering against a desk and Elsa was stood a few feet away from Jack on his right staring the auburnette down. Jack knew Elsa meant business but why? Looking at Hiccup Jack wondered idolly what he could have done to get the usually indifferent Elsa so on edge. It was time to find out.

Stepping forward Jack asked. "Someone want to tell me what's going on?" He tried to sound calm but his voice shook.

Elsa turned to him. "He's rouge."

Jackson eyes widened. "Impossible." He deadpanned.

"I saw him shift."

Jack snapped his mouth shut and took a peek at Hiccup. He was glancing from Jack to Elsa his face confused and afraid. There was no way. Jack shook his head the little control on his temper slipping away steadily by the second. Jack had a good read on people and Hiccup's reactions were genuine. The jock shook his head again.

"You don't believe me? You know there's one lose and I saw him Jack." Elsa said in disbelief her voice rising.

"You don't have anything. You could be wrong; you can't just go around accusing people Elsa." Jack's voice rising to meet hers.

Elsa took a step towards her brother her own temper and nerves seeping out of her. "Pull your shit together; you know what we have to do."

That was Jack's breaking point he whirled on Elsa. Hiccup had been silent threw the whole exchange hoping for an escape to appear. But as Jack and Elsa's voices rose Hiccup felt goose bumps blossom along his skin. The room grew colder a feeling of déjà vu flowed over Hiccup as he watched his misty breath swirl in front of him. He took a chance to look at the window, outside the sun was still beaming down on the scorched ground. The window was open a few inches and Hiccup bit his lip as a plan form in his head. A cold gust brought him out of his head and back into the room, where's the warmth gone? A quiet cracking sound hit his ears and he turned back to the still arguing twins. They were almost shouting at each other but Hiccup didn't understand any of what they were arguing about apart from that it was about him. Hiccup heard the gentle cracking sound again. He let his emerald eyes fall to the linoleum floor. Ice, ice covered the floor and it was slowly spreading. Hiccup slid around the desk away from the abnormality. The ice continued to spread threw out the room. Hiccup looked back at the two bickering twins. Elsa was now almost in Jack's face shouting and shaking, Jack in turn looked like he was having a hard time keeping himself in check. But something was bothering Hiccup again. Squinting at the two he found what some part of him had already registered. Their eyes, both of them had those cat like slits. The hairs on the back of Hiccup's neck stood up on end his brain quickly scrabbling to connect the pieces he had stored. There was something off about the twins, their eyes the cold that seemed to appear when one of them was angry, Elsa's strength, the ice. It was them, all them. Hiccup knew he was missing one last vital piece, he also knew he wouldn't make any sense of this situation without it. Then Elsa bared her teeth at Jack and Hiccup found the final piece. Hiccup didn't give another thought as he slid back to the window and using both hands he inched it up, pausing every so often to make sure they hadn't noticed. All he knew was he had to escape. After what felt like a life time but in reality was maybe five or six seconds Hiccup was able to slowly crawl under the glass. Letting his legs dangle he cast one last look to make sure his so called classmates hadn't noticed before letting himself drop. The fall was slightly higher then the teen had anticipated and he landed on the grassy patch under the window with a soft thump.

"Hiccup." He heard Jack shout.

Scrabbling to his feet Hiccup took of at a dead run. Chancing a glance over his shoulder he saw Jack land gracefully on grassy patch under the window. With a gasp Hiccup turned back to see where he was going Hiccup knew he was fast. Astrid was always telling him if he ran on a completley flat surface and managed not to trip over his own feet he could easily outrun most of the track team. Well now was his chance to put it to the test. Hiccup pushed his weakened body faster his breath already coming in jagged gasps, a stitch forming in his side. He pushed on passed the buildings, benches even the fountain in the main courtyard. Now the front gate was in view. Footfalls sounded behind him and Hiccup knew Jack was still in pursuit and closing in. Panic started to settle in but then something tugged at his conscious mind, trying to pull him back and take over but the small teen shoved it back. As he dashed past the front entrance to the school on his left the door burst open and Elsa jumped down the stairs locking on him. Before Hiccup could do anything that unknown entity in his head shoved him aside and tried to seize his body again, but Hiccup pushed back just as hard. Hiccup still trying desperately to regain his mind and body had been heading towards town but the thing fighting against his control screamed no and Hiccup gave up completely surrendering to it in a last ditch hope. It leapt forward consuming him like a fire .His body froze skidding on the gravel and his body twisted one hand shot to the ground for balance before pushing off on his hand and feet to the right. Out the corner of his eye he caught a flash of a blue hoodie before he darted towards the woods. Hiccup could do nothing but sit in the passenger seat of his mind while his body acted alone a sense of calm spread threw him. His breathing evened out long deep breaths in threw his nose and out his mouth making him feel as if his lungs had doubled in size. The stitch in his side faded and his body became light and felt strangely agile. He suddenly felt more stream line. Hiccup's vision changed everything became brighter more detailed. The little mussel Hiccup had hardened. Suddenly Hiccup felt his body surge forward at a speed he didn't know he could reach and he shot of threw the dense greenery confident he wouldn't trip or fall. He just aloud his body to run and run he did.

Jack stopped dead. He'd lost sight of him, Hiccup had suddenly changed. Everything about him changed his whole aura shifted and he was gone in a flash. Jack had never been out run by anyone or anything, but one scrawny little teen had just disappeared. Breathing hard Jack looked around there were several ways he could have gone. He heard a rustle behind him and Elsa joined his side. Though she was fast Jack was the fastest, until now.

"Jack?" Elsa asked unsure.

"I...I lost him. I couldn't catch him." He whispered in shock.

"Lost him, he out ran you?" Jack could only nod.

"That's not a problem we'll track him down the old fashion way." Elsa was shocked but hid it well, Jack was impossibly fast, but this proved her accusation without a doubt. She took a few steps forward and sniffed. "Not possible." She murmured.

"What?"

"Find out for yourself." She said gesturing to nothing but Jack knew what she was implying.

He moved to her side raised his head slightly. Taking a deep breathe threw his nose he aloud the scents to roll around. All the usual smells were there but there was something missing. His eyes widened as he realised what it was.

"Impossible." He whispered to himself.

Hiccup hadn't left a scent trail behind. That could only mean Hiccup had no scent.

The steady pounding of feet and his heavy breathing were the only sounds filling his ears. The forest passed by in a blur of greens and browns. He listened to the rhythmic sounds off his footfalls two, four, two, four it was like a steady drum beat. The scents swirled around him then one triggered his body to react. It was close he could smell it; he had been searching for it. He felt drunk off the smell. Mouth watering and senses poised. A new strength and energy flooded his body. He knew that smell it was comfort, safety and something else he didn't recognise. His body twisted, bunched and flexed in ways he'd never felt before. It was exhilarating, it was freedom. A flash in the corner of his eye located his target. Setting his body on it's new course he aloud the thrill of the chase to consume him. Pumping his body he closed the gap. He could hear his preys his gasps for air smell their fear and it excited him. Using his powerful legs he pounced. Landing squarely on his quarries back and twisting his head as far forward as he could, he gave no more thought before sinking his sharp teeth into the soft flesh of the front of his prey's throat. Warm blood overflowed his mouth streaming down his chin. Though it was it was warm it cooled quickly becoming refreshing and revitalizing. As the blood flowed freely his victim struggled and thrashed widely. His prey's movements became sluggish and lessened as they sank to the floor in a mess of tangled limbs. Tightening his grip he increased the pressure on the wet flesh in the mercy of his powerful jaws. The body beneath him grew colder and stiller. It wasn't enough he needed more. With a frustrated growl he ripped the flesh from the corpse leaving a respectable size hole in the once pale flawless skin. Unsatisfied with his lot he ripped and tore at the body with his claws and teeth cutting threw it like butter. Under the serene moon the carpet of lush greens became stained in the liquid of life. He continued to gorge on his prize. Lost in a frenzy he relished in his prize. The powerful drug like feeling coursed inside him and he threw his head to the sky and laughed in sheer joy. Ready to devour more of that supple flesh he brought his mouth back down but instead of the pure euphoria he'd been feeling something else washed over him. His eyes scanned over the honey blond braid now matted and stain in red. Panic swelled in his chest, tenderly he turned the now lifeless body onto its back. Sky blue eyes stared back at him unseeing, eyes that he had seen every emotion the person who had owned them possessed. Slowly he placed a hand on the now cold cheek of the girl.

"A-Astrid?" He whispered.

The girl remains motionless. His eyes began to burn his breath caught and snagged somewhere in his chest.

"Astrid please. Wake up." He begged as his heart wrenched painfully.

"ASTRID!" Hiccup flung himself upright.

Breathing erratically Hiccup aloud his eyes to adjust to the dim light of his room. His green long sleeved t-shirt was drenched in a cold sweat. Hiccup's messy hair was plastered to his forehead. Without a second thought he reached to his bedside table for his phone. It wasn't there. Hiccup blinked a few times, he always put it there every night before he went to sleep. With a shake of his head he jumped out of bed towards his rickety old desk. Where he spied his satchel waiting for him. Hiccup snatched it up and tipped its contents out across the desk amongst them his phone. Astrid's number was the first of maybe seven numbers he had stored. It rang three times before.

"Hiccup are you okay?"

"Astrid are you okay?" Both teens paused after asking each other the same question at the same time.

Astrid was the first to recover. "Of course I am why wouldn't I be?"

"Hummm." Hiccup bit his lip as he tried to think of something. Astrid could always tell when he was lying on the phone or not, so he decided on the truth. "I had a nightmare."

"What was it about? I'm guessing me right?" She asked voice soft. That was just one of the things he loved about his best friend. Yes she could be terrifying but she was also gentle and never laughed at anything that bothered her smaller friend. He could tell her anything.

"Y-you were dead. I think it was me w-who killed you." Hiccup whispered the dream already becoming fuzzy.

"It was a dream Hiccup. I'm sat here at home watching some shitty comedy. It must have seemed real though?"

"Yeah... Too real."

"You okay now?"

"Yeah." Hiccup replied with a small smile. His heart back to normal.

"Good... What the fuck happened at school? And I want everything. If it's not bad enough you being ill you get in a fight with that ice bitch, break your wrist. Get dragged off by Jack. Then like five minutes later Elsa comes running in and out of that damn classroom but your no where to be seen. I don't see you at end of school. I rang you 33 times Hiccup, 33 times. I sent you 27 texts and left 12 voice mails. I was worried sick in the end I rang your dad and he told me when he got home from visiting Gobber he found you passed out on the front porch. So explain."

Hiccup sat blinking. Now that Astrid mentioned it Hiccup didn't remember coming to bed, he didn't remember getting home. As he sorted threw his jumble of thoughts Astrid remained quiet. Hiccup took a deep breath and told her everything. Some of what he told her sounded stupid even to him but his best friend yet again proved her worth by listening to every detail.

"I'll kill her."

Hiccup shook his head a little and laughed. "Out of everything I just told you Elsa breaking my wrist bothers you?"

"Yes." She deadpanned.

"Just that not the fact I think they might not be you know... human?"

"Yep, if they are what you think I'm gonna start chopping up some wood with my dads axe." Astrid laughed and the auburnette couldn't help but join in, the stress of the day melting away even if just for a while.

"Astrid, you do believe me right?" Hiccup asked.

"You don't lie, no scrap that you can't lie. So yes I believe that you believe what you say, and I agree there's something off with the Barbie. And Jack's her brother so that's a given for me, but do I believe there not human." Here she paused a moment. "I'm gonna have to look into that myself. It's possible you're hallucinating from your illness, but I don't know. I'm gonna find out though. How's your wrist did you take some painkillers?"

Hiccup stopped for a moment bringing his arm up to eye level before twisting and flexing it. It was stiff with yellow and green bruises, but apart from that it seemed fine. With a sheepish smile on his face Hiccup answered. "Funny thing about that is I t-think it's healed already."
