Hells civil war

Castiel pov
(Yn)has been training  .
I don't know what she's been training.
maybe she's getting powers or fight skills.
"Cas can we talk "
(Yn)whispered .
"Yes of course "
"I was just pondering the abyss of mind and Was wandering are we partners or boyfriend and girlfriend "
"I would say so "
"Ok " she stepped on her tip toes and kissed me sweetly on the lips .
"Then I guess  I should show you something "(Yn )grabbed my arms and took me to the dungeon.
"So watch my hands "(yn) eyes twinkled a shot of bravery .
My attention went to her hands .
Her eyes were winced  shut as her expression  showed complete anger .
Her hands tensed to fists .
Ferociously shaking until flames sprouted .
"Oh my gosh (yn) with your powers you can have an upper hand on kain " her eyes went to the size  of saucers.
"That's not all "
A grin spread across he lips .
Her eyes focused on a samurai  sword on the floor .
It flew to her hands .
And made a book fall .
"So that's what you've been doing all this time "
"The thought of you getting hurt because of my father upset me too much so I thought I'd learn a couple  tricks of the trade I'm gonna show the Winchesters now you wanna come "
"Anywhere with you " I sighed .
She took my  hand racing down the stairs .
"Sam Dean I've got to show you something  "
She happily squealed .
She set her hands ablaze and telekinetically  gave Sam a book .
Dean and Sam gave me a joyed look .
"When kain comes I will defeat him  you and Sam will say my entrance I will be there and it's gonna be war "
(Yn)dimmed the fire in her hands .
Her eyes were glued to me  .
She was about to speak as well she paused in thought .
"Yeah I've got something else to tell you guys" she leaped over to me squeezing  my hand .
"Me and cas are together "she looked deep in my eyes .
"You mean together together like kiss together told you you hit jack pot man keep it pg "Dean was suprised .
Sam had a look of dismay on his face .
"Yeah I'm really happy for you two if you'd excuse us we've got a kain to be worried about "
Out of nowhere kain appeared .
And (yn) eyes went grey a darker shade than the last  .
And kain welded his sword whiles (yn) hand set fire .
"You try plunge that  blade thing in me or my friends then ill melt your face as if it were a popsicle  on the fourth of July "
All of a sudden black ruffled wings protruded out of (yn) back .
"Well look at my baby girl all grown up I've been looking for you care for a stake out "
(Yn)eyes went black hole black and stared  into his with disgust 
"As long as it's youre blood guts and gore to make up a beautiful  cocktail I'm all ears "
"Oh your words hurt so much little (yn) "
"I am not little I'm you're biggest nightmare"
(Yn) encapsulated  flame grew higher with her anxiety.
"Come on  be the girl hulk we met go get them tiger " Dean cheered a grin plastered .
"Oh it would be my greatest pleasure "
(Yn) grasped kain and deans arm tightly and then used her telekinesis  to give there scars to her then she dissipated them both of with hell fire.
Touched kains shoulder  and teleprted him back .
She looked back at the boys her eyes normal colour .
She ran to me and devoured me in a hug her eyes winced stopping the tears from trailing down her face .
I held her closer by her waist .
Sam and Dean joined in the hug .
