Y/n goes on a hunt despite her being told not to, gets stabbed but is saved
"You know I found a case. Something supernatural might be happening around school...let's go check it out?", Y/n chirped as she came down the stairs of the bunker, with her bag on her shoulder, smiling. Dean, Cas and Sam all looked up at her. "A case?", Sam asked and Y/n was just about to explain but Dean interrupted her, "Yeah I heard about that, me and Cas will take care of it, and Sam is gonna help you with homework".
Y/n's smile faded and she frowned saying, "What?! You don't even know what's going on there, I do", she tried to sound convincing. "You'll tell us right?", Dean asked as he folded his arms trying to be dominating. Y/n was no fool, she knew what he was doing and decided to trick him. After purposely waiting for a whole minute she spoke.
"Okayyyyy fine, there's been rumors of missing hearts, probably a werewolf. Just outside school, around that shady burger place I go to for lunch", Y/n lied. And to make it even more better she asked again, "Please let me come with you". "No, you're staying and doing homework", Dean spoke as he got up to pack his duffle for the case.
"But I don't have homework and I'm good at fighting", Y/n tried but Dean didn't listen. "Y/n, you said there's only one werewolf, I think we'll be fine", Cas assured her and squeezed her shoulder. Y/n looked at Sam for help but he only gave a small smile. Dean soon returned with his bag and said, "And do me a favour, don't have burgers in shady places, it's not good", and then he left with Cas following.
_______________It was 10 minutes now that they were gone and this was her chance to leave the bunker and go after the ghoul. So she executed her plan by fake talking on her phone. "Ok calm down Lucy, calm down I'm on my way ok. It's gonna be ok, don't go anywhere", Y/n spoke as she entered the war room where Sam was at. He obviously heard her and looked at her in concern.
"Sam, I gotta go!", Y/n announced and took her bag, already filled with weapons. "Wait what? Is everything ok?", Sam inquired. "I...my friend, she got cheated on and now she's drunk. She was crying and I gotta get to her Sam, can I take your car please?", Y/n acted so well Sam fell for it. He nodded and gave her the keys. "You sure you gonna be ok?", he asked and Y/n replied, "Yeah, I'll be back soon I promise", and then she left.
_______________Y/n soon reached the real location, which was a bit far from her school, a warehouse. She knew the ghoul was inside, so she took her blade and quietly walked in. She spotted it eating a dead body and cringed. She took a deep breath and attacked the ghoul, it didn't see her coming. The ghoul turned and tried to stop her but Y/n smartly kicked it in the face and decapitated it, but then suddenly someone grabbed her from behind...another ghoul.
The ghoul pushed her and immediately tried to stab her, he had a knife to her surprise and didn't hesitate to use it. Y/n caught his hand as he tried to stab her, but he was stronger so he pushed it hard and stabbed her abdomen. Y/n let out a scream but somehow she got really angry and swung her blade with all of her power and his head flew apart from his body.
"Aaghhhhh", Y/n shouted as she lied on the floor and took deep breaths to stay calm. She knew no one was coming to save her this time as she gave them the wrong address and that she had to go home as soon as possible, or else she would bleed to death.
Y/n gathered some courage and got up with the knife sticking in her. She slowly made her way to the car and got inside. She checked her phone and saw, '39 missed calls from Dad' along with messages. She chose to drive first and then decided to call her Dad on the way home.
_______________Dean was pissed because Y/n had fooled him and Cas had to go looking for her. Dean came home and instantly began calling her name. "Dean she isn't home. She went to help out her friend", Sam told his furious brother. Dean frowned and yelled, "Help out...hahahahaha who Sam? She fooled us, gave us a fake address and...she fooled you too!!"
Sam's expression changed as he understood and sighed. "And now that she's fooled us, she's on the case", Sam confirmed in defeat. "Yeah Sam no shit!", Dean exclaimed. "Where's Cas?" Sam frowned at the angels absence. "He's looking for her because he thinks she might be in trouble and she's not picking up her damn phone Sam!", Dean frustrated.
Sam saw how stressed he was and assured him, "It's ok we'll find her ok, you stay here in case she comes back, I'll get the car", Sam spoke, grabbed his jacket, keys and left. Dean decided to go with him but then his phone rang, it was Y/n. "Y/n you are so grounded, I'm making sure you are-", "Dad...I..."Y/n whispered in a painful voice.
Dean instantly knew something was wrong and his first thought was, "Y/n? Are you ok? Please tell me you aren't...", after a short pause Y/n spoke, "Yes...got... stabbed... I'm..in a car...". Dean's anger washed away and got replaced with extreme worry. "What?! Stabbed?!... honey where are you? I'm coming there right now!", Dean spat and started walking.
"I'm driving Da... don't worry... I killed them...I'll reach home soon... it's just... so blurry", Y/n stuttered in a low voice and Dean did not like this at all, if he would have let her along on the hunt, she wouldn't have lied and went alone. He would have protected her. "Y/n do not hang up ok honey? Keep talking to me, keep your eyes open please...Y/n? ...Y/N!?", he went in full panic when she didn't answer.
Dean was shit scared and there was nothing he could do to save his daughter. "Yeah...I'm here", Y/n answered after 10 seconds, the worst 10 seconds for him. "Oh Thank God, do not close your eyes ok honey, keep driving like I taught you, talk to me come on, How is school? Any irritating professors? Trevor?", he kept on talking trying to keep her going.
"You know...I hate him...aaahh", Y/n gasped loudly. "Y/n what's wrong? Y/n honey?", Dean's heart was pounding of the fear, he didn't know where she was, in what condition, who hurt her and she clearly didn't sound ok. "I'm bleeding...", this only added to his worry. And like always, he blamed himself for it.
Dean's eyes were almost starting to water but he had to stay strong for her. "I'll tell Cas to find you ok? Don't hang up....CAS!!!", he shouted looking up. He knew Cas could hear him pray like this. "No stop...I'm ... I'm here dad...I'm outside", Y/n whispered. "Oh my God...", Dean faltered and immediately ran outside the bunker.
He almost flew out and saw a car slowly approaching. Just as the car stopped, Y/n's head dropped on the window. Dean hurried to her in panic and carefully opened the door. Y/n fell in his arms and he held her gently, "Y/n? Honey? Hey, hey, open your eyes", he got alarmed when he saw all the blood and the knife sticking in her.
He carefully got his daughter out. A single tear rolled down his cheek as he held her in his arms, on a silent road filled with darkness. She was in pain and it scared him to hell. Dean began to rock her body and kept on saying comforting words hoping that would help her. And just in time, Cas appeared next to Dean along with Sam and Dean looked up.
"Cas...she...", before Dean could say more, Sam suggested, "We have to take it out". He looked at Dean and he nodded. Sam took a deep breath and pulled the knife out, Y/n gasped at the movement and began to lose consciousness. Cas came at once and immediately put his fingers on his daughter's forehead and healed her.
"Is she gonna be ok?", Dean asked Cas and he said, "It'll take a while but yes... she's ok, give her time. Let's get her in". Dean carefully lifted Y/n up and got her inside and to her room, gently placing her in bed as if if one wrong move and she will break. Even after being told that she was going to be ok, Dean didn't leave her side.
Before waking up, Y/n's eyes fluttered a little. He was shit scared, worried and angry because she didn't listen but his anger subsided as she woke up. "Where am I?...Dad?", she asked confused and tried to get up but Dean gently laid her down again. He brushed her head and said, "It's fine, you're home, get some rest honey".
Y/n calmed under his touch and went out like a light, but before dozing off she said, "m sorry". "It's ok, you're ok", Dean spoke and planted a kiss on her head. He held her small hand in his and stayed like that as Castiel admired them from the entrance. At the end of the day, you were their daughter anyway.
