Author's Note: I saw another prompt on Tumblr about an AU where only your soul mate can kill you, and well... those of you who read my stuff should know my specialty by now. In my defense, I don't see how this can even end well in the first place, but by all means, feel free to prove me wrong.

By My Hand

Part 1

It was the incessant beeping that woke him from a drug-induced sleep, and he groaned softly as his eyelids fluttered open, feeling sore aches all over.

The hospital ward was dark, illuminated only by the soft moonlight seeping through the window blinds. Squinting slightly, he could make out the faint outline of the ward's door across the room, as well as the heartbeat monitor mounted next to him from the corner of his eye. All was still, the other patients sleeping soundly in their beds, and he was just about to doze off when he noticed movement on his left.

Twisting his neck to the side apparently wasn't the best thing to do at the moment, if the pained gasp that escaped him was anything to go by. A dark hand reached for him and he instinctively flinched away, crying out involuntarily as sharp agony ripped through his body. The hand froze, but it didn't withdraw. Instead, it moved slowly towards him, as though trying to pet a startled deer, and rested lightly on his hair. He remained as still as possible, his hazy mind buzzing with questions and frantic thoughts. The hand stroking his auburn locks felt oddly comforting though, and he gradually began to relax, thinking that perhaps its owner meant him no harm.

"Who...?" Who are you? he tried to say, but his tongue was heavy and his throat parched, preventing him from speaking any further.

A figure limped out from the shadows and into the moonlight, revealing a pale looking teenager with white hair and murky blue eyes. Dressed in a worn navy hoodie and tattered brown pants, he had small cuts all over his otherwise unblemished face, as well as an ugly large bruise on his forehead. "Are you okay?" he asked softly, staring at him worriedly.

His mouth didn't feel like cooperating with him, so it was all he could do to nod, trying not to wince at the action.

"My name's Jack," the stranger introduced himself before looking away sadly. "I... I'm the one who hit you last night."

Hiccup froze, his green eyes dulling slightly as memories flashed before them: walking home from campus late at night, crossing the road when the walking sign came on, sudden bright lights blinding him with a screech of tires and something slamming into him from the side and running over his leg with a sickening crunch and -

"I was at a party with some friends. Guess I had too much to drink before I left," Jack continued, his hand beginning to tremble. "You - You were banged up pretty badly. They had to cut off your leg to save you. I know you probably hate my guts right about now, but I just had to make sure you were okay before..."

Casting his eyes downwards, it was only then that Hiccup realized that there was a missing tent where his left leg should have been. The shock of his loss suddenly hit him and he let out a high-pitched keen, his breath coming out in quick pants as his heart rate sped up. Jack's face crumpled in regret as he held the smaller teen close, trying to calm him down before the increasing beeping of the heartbeat monitor attracted the nurses' attention. Hiccup was torn between pushing him away and clinging to him for comfort. Despite knowing that he was the cause of his missing limb, there was something that seemed to draw him towards Jack.

"I'm sorry! I'm so sorry..." the white-haired boy sobbed. "I didn't mean for this to happen, I -"

He jerked away abruptly, hugging himself and taking a few steps back. Hiccup whined at the sudden loss of contact, strangely craving the other's warm touch. The immense amount of guilt in Jack's eyes made him want to comfort him, but there wasn't anything he could do while currently incapacitated.

"You'll hate me even more when they tell you what happened, but it's all my fault and you deserve to know how badly I screwed up." Jack paused with a cringe, hunching into himself. "You flatlined twice on the operating table."

Hiccup could have sworn his heart stopped right then and there. If he had died, it meant that Jack had killed him. And if Jack had killed him, then it meant that -

Jack was his soul mate.

The stunned silence that followed was too much for the older teen to bear, and he retreated further into the shadows. "I'm sorry," he whispered again, shaking his head as tears streaked down his face and dripped onto the floor. "I'm not asking you to forgive me, I just - I just wanted to see you one last time before they take me away. You won't have to worry about me anymore after this."

Tearful blue eyes met shocked green ones before Jack turned away, hobbling towards the door. Hiccup's protest died in his throat at the soulful look sent his way before Jack slipped out into the dimly lit hallway with a soft "Goodbye."

And it was only later that Hiccup realized he had never given the other boy his name.
