Now, I do not own anything Supernatural, I only own my oc Willow if I had Gabriel would have been in more episodes and lived
12 years after Ruby had died, the Winchesters still alive in their bunker with Castiel and Gabriel. But there was someone looking for them… A demon, her name was Willow so she could keep her identity safe. She had been searching for them for years and finally it was the day she did.
"Hey Cas I'm going out tell the boys when they wake up." Said Gabriel as he snapped his fingers and was gone. "If he gets in trouble I hope he knows we're not bailing him out." Castiel said to himself.
Meanwhile, Willow was getting off of a plane and started walking to the nearest diner. "Damn I'm running out of money I need to find a way to get some more" she said to herself and sighed. Her backpack was on one shoulder as she walked down the sidewalk with her head down. She did not notice her backpack was open until she had bumped into a man and fell face first "ooww~" she said looking at her wrist. "Oh sorry about that didn't see you there!" Said the man, she looked at him not knowing who he was only knowing he was an angel. All of the things from her backpack had been scattered about and she did not worry about the fact she, a demon had cashed into some angel who most likely knew the Winchesters.
"I should probably help pick up, I'm Gabriel by the way." Said the angel. "I um.. I'm W-Willow... It's nice to meet you Gabriel" She said as she grabbed a book out in the open that had a pagan star on it, Gabriel saw and looked at her a finally noticed he had come upon a demon while also finding a paper that had the names of the Winchester with places crossed off… "Where are your parents Willow, you don't seem old enough to be wandering around on your own… And may I ask why you are looking for the Winchesters?" He said suddenly turning from playful and content to serious and determined to find out the answer. "P-Please I don't mean them harm Gabriel but we mustn't speak of it here, may we please talk about it over uh lunch? I'll pay." She said with a growl coming from her stomach.
"Fine, but if you lie to me about anything I will come get you and kill you" Willow nodded in agreement while thinking of all the possible ways he could kill and torture her. Once her backpack was filled with all of, the stuff that had fallen out they walked to the nearest diner and sat in a booth across from each other. "So tell me, how long have you been looking for them exactly" Willow looked down and replied with sorrow in her voice, "about 4 and a half years… But I'm just about to give up" Gabriel looked at her confused why she seemed so sad, "And why are you looking for them, remember the truth" Willow was terrified at the fact she was sitting across from an angel at some diner and tried her best not to stutter, "Um w-well I have a-a question... Well more like a favor for them, y-you see my mother she died when i was a baby and she left someone to take her place... That s-she told me how my mother died and who m-my father was.." Gabriel was so confused he didn't know who her mother or her father was and wanted to know more. "And who is your mother and father?"
"W-Well she told me that my father killed my mom during the apocalypse... My father was said to be Sam Winchester" Gabriel eyes widened and was shocked my the answer he was given, but somehow he knew she wasn't lying, "I suppose I could take you to them, but one final question... Have you ever killed anyone before?" Willow gulped and sighed, "Y-Yes I have but only one human... I have k-killed a few demons here and there." Gabriel nodded and snapped his fingers and she was tied to a chair in a devils trap in the bunkers dungeon. "I just need to be sure you're safe before actually letting you roam around, I mean you never know."
Willow woke up the next day still in the chair but she knew someone or something was staring at her so she stayed there acting like she was asleep. Then she heard people speak and she already knew who it was even if she had never heard their voices before. "Gabe, why did you bring some little girl here!?" the voice came from who she thought may be Sam and she was correct, "Sam she isn't just a little girl she is a demon, but Gabriel why did you bring her?" said Castiel. Willow then heard behind her someone was checking her backpack, "Well she's got a spell book but it only has the stuff that would be used against a demon, are you sure she is one?"
"Of course I am Dean, just ask Cas." Said Gabe as he motioned to Cas so he could back him up. "He is not lying Dean." Willow decided it was time for her to 'wake up' so she acted as if she had just awoken from a deep sleep. She yawned "W-where am I? Why am I tied up, d-did I do something?" They all turned to look at Willow, "and the girls awake! How was your sleep little demon?" said Gabe with a threatening tone. Willow ignored his tone and replied, " I had a fine little sleep but I don't believe you could untie me? I mean I am already in a devils trap, I don't believe I will be going anywhere." They all looked at each other as Dean said with a harsh tone, "But how can we trust you? Gabe told us everything you said." Gabe looked at Dean and rolled his eyes, "And did you forget the part where I told you she was telling the truth? She was just looking for you guys so she could ask you something."
They all turned to her, Castiel getting his blade ready as Dean untied her and let her stand, "T-thanks, I really appreciate y-" she was cut off, "What do you need to ask us?" Sam had finally spoken. Willow was jumped up in surprise at the sudden voice but calmly responded, "I wanted to ask you more of a favor but, I-I... I want to live and hunt with you! You see I don't want to be a demon but there is nothing i can do about it, so I might as well live as a human... Also I hate with a fiery passion demons and i wish they all could just rot in Hell!" They were all surprised by the answer except Gabe, he saw it coming.
