Evolvement Error

Go on without me.

It's been weeks since they all lost Ava. Everyone was in mourning. Mostly Cas. One night, Kayla found him crying alone on an arm chair in the library alone as she was on her way to the kitchen to get something to drink. 
She didn't say anything. Not a word. She walked up to her husband and just wrapped her arms around him, letting him do what he want. Cry... Rant... Scream... but all he did was just sob endlessly in her neck. 
"I'm so sorry" Cas whimpered through her endless hug. Kayla closes her eyes and just takes deep breaths to control her tears before saying "it's not your fault." Cas let go of her but kept his hand holding hers. "Ava she... She had so much life to live. It's my fault for all of this." 
"No it's not." Kayla said now tears over flowing. "It's not" she repeated for reassurance. Castiel couldn't just break once more as his face was now in the crook of her neck. Kayla wrapped her arms around him again pressing kisses over his head and face. "This was supposed to be the other way round" Cas spoken as he tightened his hold around her.
"what do you mean, Guardian angel?" 
"I should be the one holding you, not you to me" Kayla softly chuckled before pressing another kiss on his head. "I've had my fair share of tears and annoying you and my brothers with my crying" she said still holding her husbands shaky self. 
"You didn't annoy us" he said not letting go. Kayla softly smiled a sad smile again before grabbing his cheek with her hand and brought him to look up to her "we're strong... All of us... we've been through so much... we deserve to moments like these. Moments to scream, moments to cry, moments to just let out any emotion that is paining you. It's alright if you cry. That means that we've been through a lot and we had kept them in for so long" Castiels blue eyes bored into her hazel ones before he pressed her a passionate kiss as a husband. His hand went behind her hair cupping her head as his keys became more rough and passionate before he pulled away. "I love you sweet treasure" he whispered.
"I love you too guardian angel" she replied mirroring his same tone. They kissed each other again, tasting each other, feeling every inch of the others skin and flesh before Cas got up, brought Kayla in his arm, Bridal style and took her to their room.

Days After, Dean was walking down a busy road to enter a gas station to buy some snacks and drinks for the bunker.
"Dean!" A female voice stopped him in his tracks before he turned and saw the last thing he wanted to see. The angel, Angelica! Now he used to have a crush on this angel but now after everything that's happened to his niece, he's had it with angels. 
"I have nothing to say to you or your brothers or sisters! Just leave me and my family alone! You've done enough" Dean gnarled at her, his nose flaring invisible fire at her feeling like he could rip her head off any moment. 
"Dean!! Please!! I'm sorry, I wish there was something I could've done!" 
"Oh there was!!" Dean now yelled at Angelica making her jump with fright and people who were passing by stare at them. His eyes spoke immense pain. He loved his niece, she was like his own daughter to him. Her first word was his favourite word... She always opened up with him when she was something was bothering her... many times of the job they have... he never let her down.. but this time... he feels like he not just let her down.. but also failed her... he felt like he was a failed father although... he wasn't her father.. he was an uncle.. he thought of her every second of every day... he loved his niece as much as though she was his... and he lost her to a bunch of pathetic excuses for angels.  "My niece was innocent... why would you want her? She was gonna be happy and normal. Why take her away from us?!?!" Dean asked now showing true emotion through his eyes as he was nose to nose with her.
"Bec..Because we needed a female nephlim. If we have 2 nephlims of the opposite sex, Heaven and earth will combine... if Hell had her, It would have been Hell on earth! It's a good thing that Ava is with us!! All we need is Jack! and Heaven will rule it all! Dean!! Please!! You gotta trust me!!" 
"Oh I did trust you!!! But now you ruined it! And you forget about Jack, you already took enough!! Now, If you'll excuse me, I have booze and snacks waiting for me" he said before pushing a "pull" door making him groan in exhaustion and frustration and yet slowly and calmly pulling the door open and entering the shop. 
"Dean!" Angelica sighed before she went to an alley and disappeared. No human can ever witness divinity. 

Dean was near the fridge, grabbed a 12 pack of beers and come snacks, paid and went to baby driving her all the way back to the bunker. 
He entered the bunker with the beer in one hand and a bag in the other and finding Kayla on her laptop and Sam mirroring his twin. 
"You know, if you look at yourselves right now, you will definitely see the twin thing between you two." Dean remarked with a smirk. The twins looked up and chuckled. 
"Hey puppy!" Kayla grinned before she caught glance of the drinks "Is that beer?!" 
"Yep! Drink up!" He suggested. Kayla smirked and took one "Don't mind if I do" she mumbled before she popped it open and took her first swing. The brothers nodded at each other as a greeting, Dean handed Sam a bottle. "Thanks" he muttered before doing the same thing Kayla did. 
"So uh... Found us a case... 12 year old girl.. changed mood. Almost killed her family... In Austin. Demon. Like to go take a look?" Kayla said looking to one brother to the other. 
Sam and Dean nodded "Sure. I hope it won't trigger you though Bunny, Cause.. 12 year old girl" Sam requested. "How about me and Dean take this case? you take your rest." 
"I've been resting for far too long.. and please... Would I have suggested this case if it would trigger me?" Kayla tried to reason with her twin. Sam and Dean just looked at each other before they hesitantly accepted her in the case. "Alright! Fine! But if you show any signs of triggering, you're gonna come here and take care of your sons and Rosie."
"My sons and daughter can take care of themselves. They're old enough. And I won't be triggered. Come on" she said before she pushed herself off the chair and went to her room taking out her duffel bag ready filled for a case like this. 
"where are you going?" Rosie's voice made Kayla jump inches of the ground with a yelp. She turned to face her daughter and breathed "Me and your uncles found a case. Shouldn't take too long" Kayla replied to her 12 year old daughter. Rosie, the black haired and blue eyed girl who looks like her father, ran towards her mother holding her tight "please don't leave me like Ava did" she begged. Kayla weakened.. She felt her heart sink. Eyes filled with pain as she tightened her hold around her daughter "it's alright baby. I'll" she stammered before she sighed and said "one moment baby girl" she said before she went to Dean in his room finding him putting clothes and essentials in a duffel bag "Hey um. You go without me" she suggested.
Dean's brows furrowed in confusion "weren't you the one who suggested this case?" 
"Yeah. I did but um... I can assign this case to you.. Can't I puppy?" 
"sounding triggering?" Dean asked but now in an even more sweeter and softer tone. Kayla didn't respond she just bit her lower lip and sighed looking down. "hey" Dean said before he found himself in front of his baby sister with his hands on her shoulder "it's gonna be fine" he oozed her calmly before he pulled her in his chest. "you don't have to come. It's alright. Me and Sam will take this case. Alright?" Kayla hugged him in return and nodded before she just nuzzled into his muscular and toned body. She felt so lucky to have brothers like him and Sam. She always felt safe with them
