As many stories do, this one begins with a once upon a time. So, let us begin.

Once upon a time, on a cold and snowy winters eve, a man in yellow was stumbling along a warn path, still a bit disoriented and looking for a safe place to stay. This man was named Eobard Thawne, and he was the Reverse Flash. He had just come from trying to kill the little Prince of a nearby kingdom, Bartholomew Allen, Barry to those he called friends. Of course, he failed in his mission, else why would he be wandering down a path aimlessly searching for shelter?

Finally, he spotted a beautiful castle on a hill. It was the castle of a royal family, and was just the kind of place he was looking for. Staggering he forced himself to make his way through the wooded area and up all the way to the ornate doors. Breathing heavily, he knocked and hoped this would be the place he thought it was.

Imagine his surprise when a small young girl, no older than the prince he just tried to kill, pulled the heavy door open enough to see. She was a tiny thing, with kind, warm brown eyes, and long chestnut hair that was styled with some of her hair pulled back accepting her shimmering tiara. Her dress was a deep blue, and she seemed to drown in the excessive ruffled skirts. Yet, she looked just darling, and he knew who she was by looking at her.

"Excuse me young miss," He started with a weary and tired smile, relief showing on his features. "Do you think that, perhaps, there might be room for a weary traveler such as myself? I promise, I would not be a bother." Using his best manners he spoke to the girl, doing his best to not look or sound as sinister as he surely looked dressed in a yellow armored suit with a mask.

"Why of course." She managed to pull the door back farther, though she struggled to do so with the weight of it. He slipped inside and helped her shut the door.

"Why thank you kindly, my dear."

"Your highness, I do believe that is for your parents, the majesties, to decide." A woman's stern voice cuts through the air like a knife, and he is greeted by a tall and lanky woman, with dull brown hair who is clearly her nanny. She grabs the small girl roughly by the arm, "You are not allowed to touch this door and you know it." Her voice is mean and she sneers at the kind girl, "For that you shall go to bed without supper."

"Oh, but madam," The girl begins, "He is a lost traveler, in need of shelter for the eve. We cannot just let him go back outside. He shall surely freeze if we do." She pleads, clasping her hands together.

"Go with your nanny, daughter." A man appears at the stop of the staircase, a woman by his side. They are both regal in appearance, dressed in finery and with crowns on their heads.

"But papa," She starts but is cut off by her mother. "Listen to your father, young daughter." Her voice is cold, devoid of much emotion as she speaks to the little girl.

"Yes mama. Yes papa." She hangs her head, and follows the nanny sadly.

"Your majesties." He greets them, "I am a weary traveler, and I was wondering if perhaps there was room for me to stay the night. It has become quite a blizzard out there, and I cannot go on."

Now the king, he was much warmer, much kinder than the queen and this is where the little girl got much of herself from. But the king, he loved his wife a great deal, and liked to please her. So, he made many a decision the way she wanted and this instance is no different.

While the king would have been more than willing to allow Eobard to stay, give him a room and something warm to eat, the queen was less inclined. "No." Her eyes narrowed, "We shall not house you. Go, and look elsewhere." She waved him off, to an incredulous look from the king.

"Oh, but my darling queen, it is a blizzard out there. Surely we can spare a bed on which to sleep and some hot food for him to eat?" The king tried to reason with her, but her mind was made and this angered the Reverse Flash.

"Oh, cruel majesty." He sighed, "For your selfishness and unkindness in my time of need, I place a curse upon you and your house." His angry voice echoed and carried in the great expanse of the entry. "I curse your daughter; shall she be cold hearted like her mother. Shall she be the death of those she touches, like the icy cold that you now condemn me to." He snarls his words, already knowing that the young princess snuck her way back and was watching unseen from a balcony above. Each word struck fear in her more deeply, and she held on tight to the bars on the bannister. "Shall she not know how to give love, until one declares their own true, honest and sincere love for her."

Eobard left in a cloud of smoke and the king and queen became fearful for their daughter. A curse so heavy, how were they to break it? This was not something they could fix on their own. It would be up to the young princess to help save herself.

Of course, Eobard Thawne is not truly a magic sorcerer or warlock. He is but a traveler from the future. He knows events that have yet to happen, he knows what they do not. What everyone else does not. This is the life she was already destined to have. He would simply, accelerate the process if he could and help turn her heart into ice so cold, making her so withdrawn, it would take a miracle for someone to want her. To truly love her.

Understand now that Eobard Thawne has become stuck in the past. His speed was lost to him, and his only hope would be to create the very person he hated most. The Flash. But oh boy, he wouldn't make it easy on him. Yes, he would keep the boy alive until he could restore his speed and go home, but until then he would give him trouble at every turn, never letting him become truly happy. He would allow him to have hope, and then he would find a way to rip it away. Not even those who were friends of the Flash were safe.

That little princess, you see, her name is Caitlin Snow.
