grief isn't an easy thing.

"Really?!?! that's a terrible plan!!!" Kayla exclaimed "I'm not gonna have our daughter be taken away from us just because she's special!!" She said almost hyperventilating. 
"Bunny. Calm down! We can do this" Sam tried to calm his twin down. 
"No!! No!! I can't!!" she exclaimed through tears. 

Everyone held sympathetic looks over her before Cas sighed "Let me talk to her. Maybe I can confide with her"
Dean, Sam and John nodded before they left leaving him pats on his shoulder. 

Cas moved over to his weeping wife before he knelt down in front of her and placed a hand on her knee. "Kayla... Listen to me... It will be hurting watching it happen... but trust me... things will go better... they won't hurt her... I made a deal... it was an oath actually... they can't do any harm on her because if they do... an angel will die.... excluding me and Gabriel.... just... trust me... Please sweet treasure. You're strong... stronger than any other human I met... You can do this.... we can do this... together..." he held her hands looking deeply into her eyes locking them.... before he saw the pain in them....his eyes turned into his "sad puppy" ones before he pulled her close to him and kissed her head "I love you sweet treasure.... But we have to do this. It's our only best option" 
Kayla swallowed her tears back down before she sniffled and nodded "alright... but don't expect me to not be effected and act like everything's ok" 
"Kayla, we can't act negative! Our kids will find out... and we can't let them... please... stay strong." Kayla sighed and bit her lip before nodding "Alright. Alright. Fine. I guess" Cas pressed a kiss on her lips. Kayla willingly kissed back before nuzzling her face in his neck again. "I hope everything goes well" 

********** 

2 months passed, Ava was 1... and Kayla's stomach was growing by the second. this was the final child they were having, no other nephlims!
 
It was 8 o clock in the morning, and Dean woken up and went over to make coffee from the kitchen finding Kayla with her head buried in her hands with a cup of coffee in front of her.
"Kitty? what are you doing up this early?" he asked concerned pouring coffee from the machine into a mug.
"I should ask you the same question." Kayla retorted
"Kitty?" Dean asked again placing the mug next to hers, placing a hand on her upper back, eyeing her concernedly. Kayla sighed and gulped, with tears reforming in her eyes "This plan... I... I don't like.. what if it rebounds? when did anything good happen to us.... if something is too good to be true... it never was... and this... is it... I mean angels?... come on!! since when did those sons of bitches ever kept their word?!" Kayla asked her voice cracking with every sentence from those phrases. "I can't!! I... I can't stop thinking.. I can't stop imagining me and Cas loosing our baby girl.... and I can't stop thinking of how can Cas ever make a deal like that!!" 

"Kayla, it's Cas! He always made arrangements like those.. and I know what you mean... I... I'm sorry for this happening to you... we can't stop it or prevent it from happening... it is gonna happen... but... we're sure that we know that it will end on a good note. Although Ava is gonna....." he stopped and gulped.... he cared for his niece.... it's not subtle to notice.... he loved her to the core...she was like his daughter.... and this was hurting him too.... "she's gonna be fine on the other end" he said covering his shaky tone.
Kayla took in a sharp inhale as a sob escaped as an exhale "why does this hurt so much?" she asked gripping a tight hold of his shirt. Dean enveloped her in his arm, closing his eyes, clenching his jaw preventing a sob from escaping, as tears were almost fighting out of his eyes, he bit his lip before he tightened his hold around his sister, kissing her head, keeping it there for a few seconds. "I know. I'm so sorry kitty. You don't deserve this." he spoke still keeping his voice from cracking. 
"I don't wanna loose my baby girl" she replied through silent tears. 
"I know! I know Kitty! I know! Ava she.... she's been a big part in our lives... we're all gonna miss her." Dean said still closed eyes and not wanting to let his sister go. 
He sighed and just kept his embrace around her. She couldn't stop shaking in his arms. This was a hard time for everyone... they have to give up Ava... they didn't have any other choice... 

*2 more months later*

Kayla was in labour. Her screams of pushing filled the bunker again... everyone yelled their support and eventually a beautiful baby girl came to play again... this time.. they named her Marble Rose Winchester... They called her rose mostly but that's her full name. 

Kayla was sleeping in her own bed all drained out from the labour as Cas was cleaning his baby daughter. Tears were prickling his eyes as a proud smile seemed to give way. "Hello Rose... welcome to the family... We all love you so much... especially mummy and I... we will do anything to protect you and your brothers and sister... no matter what...." he just came to realisation to what he said and his eyes turned grim and dark.... tears were now overflowing... they couldn't stop...the grief for his other daughter was happening now... this was bad timing but... he couldn't handle it in... he kissed his newborns head before he went back to his room and found his wife asleep. He gave a soft smile as a quiet sob escaped his lips before he slowly and gingerly placed his new born in her cradle and went besides Kayla.
Wrapping an arm around her and stroking her brown hair matching Sams, he felt his lips quivering as another tear escaped his eye. 

CASTIELS POV 

I'm so sorry sweet treasure... I couldn't... I couldn't do anything... I just wish there was someway that I can turn back in time and we could just get married... that's it... no Ava.. no kids... we were still happy the way we were but I had to bring these 2 nephlims... I love you and them so much! I don't know what I would do without you, our girls, your boys and Jack in my life... I'm so sorry! I failed you!! 

I don't know what to do with Ava's destiny... it has to happen anyways one way or another... This is gonna be so hard for all of us.... It's already hard enough for me let alone for you, Kayla... the mother... the one who carried her and held her with  comfort from your belly for 9 months... the one who sacrificed herself to bring her into the world only to be taken away from you again by my brothers and sisters. 
I'm still trying to find a way for this, sweet treasure.... Nothing is stopping me. I'm gonna keep on fighting... for Ava... for you... This... ends now.
