5 years later...

"Okay Cas, we are here," Dean said and parked the  Impala in an empty spot and shut it off. Castiel nodded and got out, walking towards the cosy looking building that served as his and your daughter's school.

Sam and Dean got out of the car as well, staying close to the car while they waited for Castiel to get his daughter from the playground.

There were loud laughs from up ahead. Castiel's daughter stood in between a group of boys... boys that looked older than her, by maybe a year or two. Castiel looked at them with his eyebrows furrowed, then passed it as his daughter making new friends.

THUMP!

His daughter fell to the floor, one of the boys had pushed her. The boy started laughing, an evil grin on his face.

Castiel clenched his fists and stormed ahead. He daughter started crying a little and once she saw her father she scrambled towards him. "Dada..." She mumbled and hugged onto his leg.

"HEY!" Castiel yelled and walked closer to the boys. The kids started to tremble with fear a bit, feeling afraid of the angry adult staring at them.

HONK! HONK! HONK! BEEP! BEEP!

The cars around started to act crazy, screaming out and alarming everyone around them. People tried to switch their cars off but couldn't, and started to get frustrated with the keys in their hands.

The street lights started to flicker, the kids began to run around feeling extremely scared. The bullies that were near your daughter looked at him with horror.

"Cas, what are you doing?!" Dean whispered furiously as he hastened to his angry friend. Sam was about to put his hand on Castiel's shoulder but stopped when he glared at him.

The Winchesters backed away, looking at everyone around them nervously. Castiel walked ahead and stopped, pushing his daughter behind him slightly and placing an hand on her shoulder and bringing her closer protectively.

"What's your name?!" He questioned the boy who pushed his daughter and all the noise and flickering lights stopped abruptly.

The boy looked at his other friends, who started to back away. "J-J-Jackson... sir," He stuttered and fidgeted with his shaking hands.

"Why did you push my daughter? Who gave you the permission to treat Willow with disrespect?!" Cas asked, fuming with rage. The boy shook his head, "No one did, I-I-"

Castiel's eyes started to glow blue, his powers starting to work on the kid. He started to threaten Jackson, just by glaring at him with his powers.

Willow looked at her father with confusion, asking herself mentally about why her daddy had glowing eyes right now. She continued to look at him with fascination, hugging tightly onto his arm so that she feels safe.

"Dont push her again, okay?! Don't push anyone, it's not nice!" Castiel yelled and the boy nodded his head quickly, then ran away screaming and crying in fear.

Castiel picked his daughter up and kissed her on the cheek. "Daddy, I was so scared... thank you for saving me," She said and hugged onto his neck tightly, nuzzling her face into his neck.

Cas held her closer to him and placed a kiss on her head, walking towards the Winchesters who waited by the car.

People continued to stare at him, whispering to others next to them and giving him peculiar looks. Castiel glared at them, clinging onto his daughter more tightly as she continued to talk to herself.

*****

She's got eyes of the bluest skies
As if they thought of rain
I'd hate to look into those eyes
And see an ounce of pain

Her hair reminds me of a warm safe place
Where as a child I'd hide
And pray for the thunder and the rain
To quietly pass me by

Sweet child o' mine
Sweet love of mine

Where do we go?
Where do we go now?
Where do we go?
Sweet child o' mine

Castiel concluded singing 'Sweet Child O' Mine' by Guns N' Roses, Willow looking at him in awe. Castiel always sang that to her as she got ready to go to bed. The song reminded him of his daughter, 'She's got eyes of the bluest skies'.

"Alright sweetheart, goodnight," Castiel said softly and kissed his daughter's head as she snuggled under her blanket. "Bye daddy, I love you," She said, "Thank you for saving me today."

Castiel smiled lightly and ran a hand through his daughters hair, "It's my job to protect you Willow, no need to thank me."

He shut off the bedside lamp and the night light immediately turned on. Castiel walked out of the room and left the door slightly open.

Moments later, someone came running to Cas and wrapped their arms around him from behind. The person kissed his neck and Cas turned around slowly.

"Hi Elena, how was work?" Castiel asked after planting a kiss on your lips. "Work was good, I missed you... like always," You said and grinned a bit. He held your hands as you started to walk towards the kitchen to have some coffee.

You asked him about the day, about what he and Willow and the Winchesters were up to. He told you everything, your daily routine with nothing that special taking place, but paused a bit when he approached the part of the event at school.

"What?! Really?" You exclaimed with shock and Cas nodded, sighing and looked at your hands as he held them tighter. "But I threatened Jackson and told him not to push Willow or anyone ever again," He explained, "I used my powers on him and he ran away like a child."

"Cas he is a child. I mean, I don't know if you had to be that harsh," You frowned, "They are kids after all and it could help to make Willow a stronger person if she's faced with people like this."

"So I don't protect my only daughter from harm?!" He clenched his fists, starting to feel anger within him. You hugged him, rubbing his back softly, "No, I'm not saying that. We should protect her and more, teach her how to fight back."

Castiel nodded and sighed. "I threatened the other kids that were near her too," He stated and you rolled your eyes. "Okay Cas, thank you," You responded, slightly chuckling at how protective he is towards your daughter.

"Dada! Dada? Where are you?" You heard your daughter call out, light footsteps approaching the kitchen followed afterwards.

She had her blanket in her hand, part of it wrapped around her shoulders. Once she saw you, she ran towards you and gave you a hug.

"Mommy! You're home!" She said excitedly and you smiled, kissing her on the cheek. "Hi darling, how are you doing?" You asked, "Why aren't you asleep?"

She looked to her dad the frowned, "I couldn't sleep. Daddy didn't read me a story." You looked at Cas with an eyebrow raised and a smirk plastered on your lips. Cas smiled the  got up, holding his daughter's hand and leading her to her bedroom.

While Cas read her a story, you got settled and changed your clothes. You washed your face and brushed your teeth then walked to your daughters bedroom.

"Daddy can I see you wings?" Willow asked, slightly hesitant. Castiel thought for a moment then nodded. He took his daughter by the hand and placed his hand over her eyes to shield her from the bright angelic light.

Willow always loves seeing and maybe playing with her father's wings. She assumes all little girls have fun because all dad's 'probably' have wings too right?

"Can I open my eyes daddy?" Willow asked and Cas uncovered her eyes. She squealed with happiness as soon as she saw them, and ran towards one of the wings. She hugged onto it and ran her fingers through all the soft black feathers.

C

astiel groaned a bit, the human touch on his wings made him feel butterflies inside. When you touched them... it made him feel something COMPLETELY different than to when his daughter does.

"Daddy their so soft! I love them!" She giggled as she burried her face into them. Castiel smiled, rubbing his hands constantly together to ignore the weird feeling in him.

"Alright sweetheart, you can play with them later," Cas said and Willow frowned, "Come on, you need to sleep."

Castiel picked her up and hugged her. Willow kissed his cheek and Castiel wrapped his wings around her, causing her to laugh. "D-Daddy my st-stomach hurts! S-STOP!" She laughed as her father's wings tickled her.

You watched quietly as you stood by the door, a smile on your face. Castiel walked out of the room and jumped a bit to find you there. You hugged him on sight, spotting his wings that were still visible.

You snuck your hand towards them and ran your fingers through them. He moaned lightly and you chuckled. "Please continue... but not here," His eyes darted all around, looking infront then behind himself incase someone was watching.

Little did he know that his daughter saw everything, and giggled a bit.
