"CAS! CASTIEL!" You yelled as you saw the love of your life walk ahead with rage. He kept going, ready to face Lucifer.

"CASTIEL COME BACK GODDAMMIT!" You demanded, shouting at the top of your lungs. He turned back, looking at you and feeling sorry. He shook his head and that made you freak out.

Sam grabbed you tightly by your arms and pulled you back as he jogged. "I HATE YOU CASTIEL!" You yelled and before you knew it, you were-

ZAP!

You stood back in your own reality, no sign of Cas anywhere. You kicked the ground and looked at Sam and Dean with anger. "Couldn't you guys do something?!" You yelled.

Dean was about to answer but there was a bright light.

"Oh my God, Cas!" You said with happiness, once you saw him emerge from the supernatural crack in time and space, courtesy Kelly's nephilim.

You stepped to him but a bright, stinging beam of light shone from within Castiel. His eyes lightened up and you screamed.

"NO! CASTIEL!" You shouted, covering your eyes. You could hear him, he was in pain and tears stung your eyes.

"I'm s-sorry Kyr-ra."

He fell to the floor, Lucifer standing back with an evil smirk. "What was I supposed to do? He was in my way," He said and you stormed to him.

"SON OF A BITCH!" You spat in his face. He furrowed his eyebrows and raised his hand, swiping it to the side and causing you to fly to the side and hit your head on the floor.

Dean and Sam stared at you then turned to Lucifer standing infront of them. "Now that the girl... friend is out of the way, I can deal with you two," He grinned, his voice was irritating.

"No."

Everyone looked to the side as you used a tree as support to get up. "Oh look, the girlfriend is all good!" Lucifer said playfully and you glared at him.

"Y-You've ruined this w-world, you've ruined our lives... and you've taken m-my happ-iness away," You took a deep breath, limping as you walked towards him.

You glanced at the stiff body of your Angel laying on the floor and sighed.

"You will not get away with this... Lucifer," You clenched your jaw and stood upright. He laughed and it was enough to make you run to him, but you didn't. You had another plan.

"Oh and what are you going to do about it?" He placed his hands on his hips and raised an eyebrow, smiling smugly.

You took a deep breath and shut your eyes. You mumbled something under your breath and the smile wiped off of Lucifer's face.

Light illuminated within you, you felt power seep into every corner in your body. It would have fried anyone to ashes but not you... You had special help.

"W-What are you doing?!" He questioned, taking a step back, as you raised your hands ahead. Sam and Dean stepped way as well, covering their eyes as you shot all the power you mustered within yourself towards Lucifer.

It was like lightning, a spark of electricity that shot Lucifer back. He tried to pull himself up straight but you kept walking forward.

He cut your power off, he lit up as well and laughed. You growled and placed your feet firmly on the ground.

You forced the power put of your hands again. "THIS IS FOR KILLING CAS!" You yelled as you could feel yourself using all the energy you had inside yourself.

It was too strong for Lucifer and he was pushed into the crack in time and space. Sparks flew everywhere as the supernatural tear zapped out of existence.

You fell to your knees, shivering as the energy inside you faded out. Sam and Dean ran towards you and you looked up to them.

"Kyra, are you okay?" Sam asked and you have him a weak smile. "I'm... fine," You groaned and squeezed your eyes shut, "Hell no, I'm definitely not okay."

Dean held you up and raised his eyebrows, "That was... awesome Ky." He grinned and you smiled, feeling faint. "How did you do that?" Dean asked and you frowned.

You looked to Cas. He had taught you how to harness the powers of an Angel and use them without getting electrocuted or disintegrated.

You teared up, slightly detached. "I hate you Castiel... that's the last thing I said to him," You said hopelessly. Dean frowned and Sam stared at the ground.

Sam looked to the house where Kelly and Castiel were staying. The lights flickered, making him run towards it and check it out.

"Go and see the nephilim," You said tiredly. Dean shook his head but you pushed him. You watched him jog off, glancing back to you every few moments.

You limped to Castiel's body that lay in the same position this whole time. He had a hand on top of his stab wound, his head tilted to the side and his eyes shut.

You collapsed onto your knees, tears streaming down your face. "C-Cas..." You caressed his cheek then kissed his forehead.

A sudden rush of anger and grief hit you and you grabbed his shirt collar. "GODDAMIT CAS! Wake up please! Don't leave me alone!" You yelled, resting your head on his chest and hitting him with your fists.

You cried, staining his shirt with your tears. You looked up and whispered into his ear, "Baby please..." You bent over and kissed him on the lips, wanting him to kiss back but of course... there was no response.

You would have tried to bring him back, you have the power, but you used all of it in putting Lucifer through the crack in time. You're not sure if you'll be able to charge up enough ever again.

You lay next to Castiel, hugging him and resting your head on top of his chest, as you'd always do when he'd sleep with you.

You moved up a bit, touching your forehead with his, "I love you Cas."

Everything came back to you in a tsunami size of wave.

They were memories. The memories of Cas were running through your head like a movie. The power you learnt from him enabled you to see every memory.

The day you met him. He couldn't take his eyes off you. You couldn't stop the grin that was on your face.

The day you got lost in the rain with him. It was where you had your first kiss with Castiel... and it was so romantic... and cold.

The time you and the boys went bowling. Castiel had no clue of how to play and kept questioning why the game was so violent, hitting the 'mini soldiers' down. You kept reminding him that it's a 'game'.

The day it was freezing outside but you were in the complete mood of having a big bowl of ice cream. You walked with Cas to a ice cream stand and it was the time Castiel found out what a brain freeze is... and how much it hurts.

The memory of the time you gathered your courage... You slept with him and it was the best night of your life, which opened your eyes and you realised that the innocent Angel isn't that innocent after all.

You smiled through your tears. You lifted your head up and kissed his forehead. "Thank you Cas... Thank you for giving me a reason to live," You touched his head with yours again and sniffed.

"Step aside Kyra," A voice demanded and placed a hand in your shoulder. You looked back with horror as glowing yellow eyes stared back.

It was the nephilim Jack, you assumed, and he seemed to know something you didn't. You moved away from Castiel's body after Sam and Dean nodded at you.

"What is he doing?" You whispered to Dean, fearful at not wanting Castiel's body to have any harm.

"We asked... more like forced the guy to bring Cas back. The guy definitely has the power to, being half human and half Angel," Dean responded and you nodded, feeling a bit scared.

Jack placed his hand over Cas' head, pressing slightly. A light emitted from his hand, which transferred to Castiel's head and through his whole body.

Cas jerked a bit, you held Dean's hand involuntarily and he looked at you with concern. Jack squeezed his eyes shut as if in pain then all of a sudden all the light vanished.

Jack stood up straight, looking down at Cas. You couldn't believe what was happening.

Castiel groaned and blinked his eyes, squinting and looking up at the four people staring down at him.

"Dean? Sam..." He said hoarsely, struggling to sit up, "Where's K-Kyra?"

You bent down and hugged his neck in a hurry, "Oh Cas, I'm here." You pulled away, looking into his eyes with tears. He held your face with his hand and kissed you on the lips. It made you feel good inside.

"I'm... I'm so sorry Ky," He said when he pulled away. You looked at him for a moment then slapped him hard right across the face.

He looked at you with confusion and fright, you furrowed your brows and hit your fist on his shoulder.

"You-You... ASSBUTT! Stupid idiot!" You shouted into his face and he winced, "I told you to come back! You're so-"

He pulled you into a kiss to cut you off. "Just... don't be an 'assbutt' in the future," You said and pressed your forehead to his. He shut his eyes and rubbed your arms.

Sam and Dean stood there, happy and slightly awkward. You helped Castiel up to his feet, wrapping an arm around his waist for support.

Dean hugged him tight, "Good to have you back man." Sam hugged him too, smiling with relief. Jack stood their, a bit out of place.

Castiel walked up to Jack, "Thank you for bringing me back." Jack nodded then Cas walked up to you and side-hugged you.

The others started walking ahead, leaving you alone with Cas. "I... I used my powers to put Lucifer in the other world," You said and bit your lip.

He raised his eyebrows then kissed your head, "That's my girl. I love you Kyra."
