6 YEARS AGO

Dean Winchester watched his partner in crime as she flicked through a dusty old book from her adopted father's collection. They sat underneath the large oak tree that was a mile south of her home; the spot had become their place shortly after they had been introduced. His father John had been to ask his old friend Bobby's advice on a case, bringing his sons with him; he allowed Dean to wander around the land with the slightly younger girl and they became fast friends.

Bobby always called them Tweedle Dum and Tweedle Dee due to their similarities; always finishing each other's sentences and knowing what the other was thinking before it even crossed their mind. He had always said that was why they were such a good team. It was completely expected when the pair decided to hunt together, both of their fathers were aware of the promise they had made to each other in their younger years and although John wouldn't admit it, he was glad that Dean had someone to depend on especially after Sam left for college.

Allie rubbed her temples as a pain shot through her head, her ears were ringing and with every blink came a new vision or bright light. The young hunter had always had special abilities, she could feel things and see things before they happened, feel the emotions of others and see their future by the slightest touch. Dean stared at her as his brow creased in worry. He knew that she was dying and it killed him, she had grown more powerful recently but it seemed to be consuming her. The visions were constant, as were the headaches and she had been vomiting frequently due to the overwhelming emotion that washed over her. Allie refused to entertain the idea and merely told him that she was okay but he always knew when she lied.

Her heart rate increased as her palms became sweaty and her stomach churned.

"Dean stop worrying; you're making me ill." She muttered as she rubbed eyes. Allie wasn't an idiot, she knew something was severely wrong with her, she lacked energy and her perception seemed to be in overdrive. She had been dreaming recently about the shadow of a man and the wings of an angel, a voice kept telling her that she needed to stop and listen to him but she always jolted awake before she could hear his message. Normally, she would assume that it was just the standard dream of a worried girl but nothing was normal in her life. It never had been; from the day Bobby had saved her from a demon as it killed her parents and brothers to the day she went on her first hunt. Allie's normality was everyone else's fantasy. "Can we go back to the house? I feel sick." Dean didn't need to respond as he would always do whatever she needed him to.

As they arrived back at the house, the colour had drained from the girl's face. Bobby looked at her cautiously before eyeing the young man who stood beside her. Allie muttered something about going to get cleaned up before they headed out on a case as she ran upstairs to the bathroom, she knew that the men wouldn't allow her to go but she needed to keep her mind occupied.

"Any information?" Dean asked the older man hastily, "We need to find out where her power came from if we have a chance at saving her. Bobby, I can't lose her. I won't lose my best friend."

Bobby wanted to deliver good news but he couldn't. Since he realised the girl's abilities he had searched every lore book but he came up with nothing relating to females with a similar skill set. He was at a loss and it broke his heart, he had never wanted children but from the moment that he had laid eyes on the little girl of 4 years old he fell in love and 17 years later she was his world. "I don't know what to tell ya, kid." He muttered as he rubbed his hands over his face, he would never be prepared to lose her.

Allie clutched the side of the bathroom sink, her knuckles white as snow. Her whole body ached with a searing hot pain and she coughed up dark, red blood. Tears streamed down her face, she couldn't control herself. Her mind flooded with images of a certain future, she could see everything. She felt the worry and heartache omitting from the men downstairs and it killed her, she couldn't make it stop. She bit down on her tongue and arched over the sink as an indescribable pain twisted her mind and tore at her soul. Allie lifted her head slowly to look in the mirror, her face was bloody and her eyes kept fading from their usual green to a deep purple. She was dying, these abilities that she hated with every ounce of herself were tearing her apart from the inside out. She screamed as the pain intensified, the sink broke in hands as she squeezed it tighter and the mirror cracked with her stare.

Footsteps thundered up the stairs as Dean and Bobby ran to her aid, the young woman went to call to them but she couldn't find the words. Suddenly, a bright white light consumed her as she lost consciousness.

The men burst through the door only to find nothing but a shattered mirror and a broken sink coated in blood. Allie was gone.

"Where am I?" The girl groaned as she took in her surroundings. Bright white walls, a tiny window and white iron bars. She was in a cell.

"Heaven." A man answered, she recognised his voice from her dreams, "You need to learn control and you couldn't do it alone."

"Am I dead? Who are you? Why am I in a cell? I didn't do anything!"

The man stepped into her cell with her, being sure to lock himself in. He explained to her that he was her guardian, an angel of the lord who had been tasked with her protection since the moment she took her first breath. His name was Castiel.
