Chapter One

"Shit, Sammy, her pulse is pretty weak!" Dean Winchester declared, his fingers on the strange girl's neck and wrist.

"Let's get her into the car, Dean," his brother, Sam Winchester, suggested as he hurriedly opened the back door of the black impala.

Dean nodded, scooping up the unconscious but weakly shivering girl. He gently laid her across the backseat, using some spare clothes as a makeshift pillow. Straightening, his attention was drawn to his brother who was standing right behind him.

"Sammy, you good?" He then noticed that his brother's eyes were glowing blue slightly and sighed. "Or Zeke?"

"You must kill the girl, Dean," Sam, with the seriousness of the angel that was inhabiting his body, said.

Dean did a double take. "Er, come again?"

"I sense the taint of hell within her. Kill her, now," Ezekiel insisted.

"Woah, woah, what do you mean the 'taint of hell'?" Dean backed away slightly from the girl. "You telling me she's a demon?"

"Indeed, though I will admit I am surprised she is in this condition," the angel replied. "But perhaps we should see this as a boon."

The older Winchester grimaced and ran a hand over his face. Sighing, he reluctantly drew the knife that he and his brother had been using for years to kill demons and approached the prone body of the young girl in the backseat of his car.

Before he could get closer, Ezekiel suddenly let out a cry of warning just as the girl writhed and fell out of the car onto her side. Both men were then thrown backwards, landing on their backs on the road, as she struggled to her feet.

Groaning, Dean and Ezekiel looked up to see the girl standing hunched over with her hands pressed to her head. What really drew their shocked attention however were the two shadowy wings, and accompanying glow, that were raised almost defensively behind her.

"Uh…Zeke…I don't know about you but I was under the impression you said she was a demon?" Dean whispered loudly. When Ezekiel only gave a perplexed nod, the Winchester pointed at the girl's wings. "Then how the hell does she clearly have angel wings and, from what I can tell, the matching grace?!"

"I-I have no answers to that, Dean Winchester," the angel confessed. He then frowned. "But if she is a demon with an angel's grace, or the other way around, she is an abomination worse than even a Nephilim." His shoulders slumped. "I doubt that we can kill her, so I suppose we should make our peace with the world now."

"Great, just bloody fantastic!" Dean grunted, rolling his eyes. Inspecting the girl, he hummed thoughtfully. "Don't suppose you recognize the grace?"

His companion reluctantly scanned the girl and his eyes widened. "I don't recognize it but whoever the grace belonged to…they were close to the power of an archangel."

"Well, shit, how the hell did a demon manage to get the grace of an angel like that?" Dean wondered idly. However, Ezekiel's next words made his blood turn cold.

"It also appears that the demonic taint within her is that of the first demon, Lilith."

Dean slowly turned towards the angel, disbelief in his eyes. "No, that's impossible! We ganked that bitch years ago! Well, Sammy did and it turned out to be the wrong thing to do at the time, but still!"

Ezekiel shrugged. "That's what I can sense, Dean. I am surprised that we are still alive, to be honest."

Indeed, far from the angel's previous words about their imminent demise, the girl seemed to not be making any moves to kill them. Rather, she had sank to her feet, curling up on herself, while her wings seemed to be relaxing.

They stiffened when the girl's eerie eyes, black ringed with gold, peeked above her arms and locked onto them. All three of them remained there for several seconds unmoving, studying on the girl's side and uncomfortable on the two grown men's side. The girl's eyes roamed over Dean, taking in every detail, before they switched to Ezekiel in Sam's body. Widening, the girl cautiously uncurled and stagged to her feet. Dean and Ezekiel took an involuntary step backwards at this.

Dean would always look back on what happened next and laugh.

The girl tilted her head curiously before she suddenly giggled, saying with a heavy Scottish accent, "You have such a pretty glow, mister!" It was clear she was addressing Ezekiel with her words.

The angel blinked while his companion covered the urge to snigger with a cough. Dean then focused back on the girl and cleared his throat.

"Hey there…girl…" He began hesitantly. "Er, what's your name?"

The girl let loose a radiant smile. "Catriona Janetta MacLeod! But usually people call me Cat or CJ!" She tilted her head, her wings ruffling alongside the movement. To the surprise of both men, her wings were slowly becoming more pronounced, as if they were physically appearing.

"Uh, I'm Dean, this is my brother Ze…I mean, Sam," Dean replied, before pulling Ezekiel aside and hissing, "Hey, her wings are looking mighty solid right now! And I can't help but note that hers are, y'know, unbroken!"

"I do not know what to tell you, Dean," Ezekiel whispered back. "As far as I am aware, all angels no longer have fully functional wings…I should know." He contemplated the situation. "Perhaps this Catriona is an angel that was on Earth before the fall? And somehow was infected by demon blood?"

"Yeah, the blood of a demon who was killed ages ago, how ya gonna explain that one?" Dean asked sarcastically. Glancing over at Catriona, he struggled to hide the smirk at the sight of her bouncing up and down, higher than any normal human, and giggling happily. "And she sure looks like she's gonna kills us, doesn't she?" He continued in a sarcastic tone gesturing to the playing child.

"I…may have assumed too quickly about that outcome, yes," Ezekiel admitted. "But still, we must be on our guard."

"Right…hey, think you can give Sam control back?"

"And how will you explain the girl being lucid now?" Ezekiel asked.

"Just…get in a position that looks like she knocked him out, I'll tell him the rest," Dean grunted. He then approached Catriona slowly. "Hey, uh, Catriona…I know we just met but could you do me a BIG favour?"

Catriona settled back down to the ground and fixed Dean with a look full of child-like innocence. "Depends on what it is, sir!"

"Sir, ha…er, right. Now, this may seem like a bit of a strange request but…" Dean sighed before continuing. "Could you perhaps…knock me out?" He tried to smile confidently. "It'll be like a game! But let me explain the rest…"

At the word 'game' Catriona's eyes lit up, literally, as she clapped her hands and cheered. "Yay, okay!"

"Wait, wait hang on…!"

Before Dean could say anything further, the young girl raised her hands and he was blasted back. The last thing he saw before unconsciousness took him was her smiling face as she turned to Ezekiel who backed away.

"Do you need me to knock you out as well, Mister Glowy?" Catriona asked cheerfully.

"I would prefer that you didn't," Ezekiel replied dryly. He glanced down at the now unconscious Dean. "Though, now that we are alone, perhaps we could have a talk?"

"Sure! Just tell me when you want to go to sleep and I'll do that right quick for you!"

"Indeed…I suppose the first thing I would like to know is whether you are an angel with demon blood, or a demon with an angel's grace?"

Catriona shook her head. "I'm neither! I'm a witch." She grimaced slightly. "Some bad people put stuff in me and now…" Her smile was back. "Now I'm waaaay cooler! I mean, I don't like the pain and everything but I've got wings! Aren't they cool? I wonder what else I can do now?"

"Yes, your wings are rather…unique," Ezekiel agreed, smiling slightly as Catriona ruffled her feathers proudly at his words. "Another thing I would like to know now is do you…feel the need to murder anyone? Do you hear dark whispers in your mind telling you to burn down the world?"

"Why would I want to do any of that?" Catriona gasped, looking genuinely scandalized.

"I don't know. Do you have a reason to do so?"

The girl pouted, thinking hard, before she let out a small breath. "I-I do remember…hurting the people who gave me superpowers recently, I think. B-But I didn't mean it, I swear!"

"What exactly did they do to you?" Ezekiel asked keenly, interested now to find out how a child had come to be so powerful. "You mentioned these people before."

The angel listened as Catriona explained how she and her mother, who had also been a witch, had gone to investigate a crashed comet on the outskirts of Cardiff, only to find a group of shady individuals already at the site. Before they had been able to escape, more people had surrounded them. Her mother had tried to fight them off but that had only resulted in her being immediately shot. When her mother's body had hit the ground, unmoving, Catriona had been magically put to sleep, only waking up when she had felt a searing heat enter her veins, but once again going unconscious when the pain had been too much. The next thing she knew, she had woken up in the back of a car feeling much better and far stronger than before.

"And that's when I saw you and your friend, Mister Glowy!" she finished cheerfully.

"My name is Sam," Ezekiel corrected her, at least as far as his vessel's name was concerned.

Catriona studied Ezekiel as he ruminated on her words before stunning him with her next words.

"Isn't it crowded in there with two people, Mister Glowy?" she asked curiously.

Ezekiel was astonished for a split second before he tried to be evasive. "I am not sure what you mean, Catriona Janetta MacLeod."

"It's just Cat or CJ, remember?" Catriona rolled her eyes. "And I mean, I can see two different lights within you. One seems…sad and in pain, but the other is you I assume, since it's all bright lights and…warmth." She hummed. "But you also seem a little broken."

There was silence between them as they simply stared at one another, one in complete shock while the other thought they were having a staring contest.

Eventually, Ezekiel broke the stalemate. "Please, you must not tell the other one inhabiting this body. He is Sam Winchester, I am an angel of the lord known as Ezekiel."

"Why are you sharing the same body though?"

"Sam is in great pain, as am I, so I am healing him while I recover at the same time," Ezekiel explained.

"Oooh…" Catriona nodded along as if she understood, which she definitely did not.

She surprised Ezekiel again by suddenly appearing directly in front of him. Before he could move in response, she had put a hand to his forehead. He could feel her then, sweeping though his mind, but to his curiosity it was if she were being guided by instinct rather than intent.

Concentrating as he was on her presence within himself, the angel only became aware of a warmth suffusing his entire being when his grace flared with a strength he had not felt since falling from heaven. He jerked backwards in surprise at this as Catriona wobbled on her feet, eyelids fluttering before she fell backwards onto her bottom, breathing heavily.

"What did you just do to me?" Ezekiel demanded forcefully.

"I-I don't know…but whatever it was your bright light looks even brighter now, Mister Gadreel!"

Ezekiel froze; once again this small impossible girl had blindsided him with her knowledge. "My name is Ezekiel, I do not know who this Gadreel is," he attempted to lie.

Catriona pouted and pointed a finger at him. "Nuh uh, I saw into you just enough to find out your real name! I don't know why you're complaining, Gadreel is a way cooler name than Ezekiel!"

Gadreel paced nervously for a moment before he glanced at Catriona. "Please, you cannot tell Dean who I really am."

"Why not?" the girl asked. She then lowered her voice into a loud whisper. "Is it because you're a spy running from some bad guys so you have to be deep under cover or something?"

"Er…yes, that is exactly that," Gadreel attempted to smile. "There are some bad people, with abilities like you and I, who would like nothing more than to kill me. I hid inside Sam Winchester in the hopes that I could remain undetected so that's why I need you to pretend you don't know my real name."

"Ok, I can do that Mister Gad…I mean, Ezekiel!" Catriona nodded, a determined look on her face. She then tilted her head. "Bet you're happy I healed ya, huh?"

"What are you talking about?"

The girl giggled. "I saw that your wings were broken so I made them whole! You should take better care of yourself, Mister Ezekiel!" She glared at him reproachfully.

Gadreel blinked before he tested her claim. He felt a moment of disbelief when, just like she said, he could feel his wings spread out behind him, whole and strong as they once were before he had fallen. The angel looked within himself then and saw that every small injury done to his grace had also been healed. Catriona had not lied; she had repaired him fully, perhaps even more so than he had ever been.

"How…how can you have this power?" he asked, amazed.

Catriona giggled. "Magic, silly!" she chided him happily. "And I'm a cool superhero! Heroes should help the meek and the hurt!" The child struck a pose, hands on hips and chest out as she let out a confident laugh.

Gadreel smiled slightly. "I suppose that is correct. You have an interesting outlook on life. A pure one; it is refreshing." He then flexed his wings again, relishing the feel of being whole once more before looking down at Dean. "Those are all the questions I have for you now. I suppose you should knock me unconscious now."

Catriona snapped to attention, nodding and without so much as a 'by your leave' slammed Sam's body backwards into a nearby tree. Before he allowed unconsciousness to overtake him, Gadreel suggested that Catriona should also get into a position as if she had knocked herself out, so as not to arouse suspicion from his current vessel.

As Sam's body slumped to the ground, Catriona carefully went back to the backseat of the car, laid herself down and closed her eyes, giggling to herself about how fun these new people seemed to be.

Sam groaned as he came to, slowly crawling to his feet as he shook his head to clear the dizziness. Looking around, he saw his brother lying nearby, not moving but still alive judging by the way his chest was slowly moving. He went over to Dean, crouching down and shaking his brother lightly on the shoulder.

"Hey, Dean, wake up," he said.

After a few seconds, the older Winchester grumpily came back to consciousness. Accepting the helping hand from Sam he was back on his own feet quickly, pretending to look around in a panic.

"Sammy, what the hell just happened?" he asked in what he hoped was a believable tone. He breathed an internal sign of relief when it appeared that Sam had bought it.

"Dunno…one moment I was checking around while you dealt with the girl…" Sam trailed off before he whirled around towards the car. "The girl! Is she alright?"

The two brothers rushed to the Impala, just in time to see the girl begin stirring, groaning as she squeezed her eyes shut tighter against the car's interior light. She sat up to see the Winchesters looming over her, worriedly, and let out a small scream.

Neither of them knew that she was internally giggling at her playacting.

"Hey, hey, it's alright, we aren't gonna hurt you," Sam said in a soft, gentle voice. "Did you happen to see what knocked us out?"

The girl looked up at him guiltily. "Um…that might have been me, sorry. I don't have a good control over my superpower so it may have gone a bit…mean on you two."

Sam blinked. "Superpower? What do you mean?"

Dean, of course, knew exactly what she was and what she was talking about but kept his mouth shut, hoping that the girl wouldn't give Gadreel's presence away.

The girl hopped out of the car, stumbling slightly and resting against the Impala for a second before straightening herself up to her full, real, tiny size.

"Lemme show you a little bit of why I'm a cool superhero now!" she declared impressively.

To Sam's utter shock, Dean poorly pretending to be shocked as well beside him, huge wings spread out behind the small girl. Each wing was easily as large as the Impala was long with feathers that look as black as night but on closer inspection were in fact a deep purple. The most prominent feature about them though, which surprised both brothers, was the fact that her wings were fully solid, evident by the shadows they were casting in the moonlight.

"What the hell?" Sam shouted in disbelief, as Dean facepalmed behind him.

And that concludes that chapter.

If it wasn't obvious from this chapter, I'm gonna be saving Gadreel the sad fate that befell him in the series. I feel like the way he went out was a massive disservice to what could have been a potentially awesome member of Team Free Will. So, I aim to rectify that. Don't worry, Gadreel will get his original vessel back, but I'm unsure how at the moment.

Stay tuned!
