(Yn)was growing more depressed .
She didn't show it but I could see it in her eyes .
How they were clouded how they were becoming more dull .
How when her demon side shone her eyes would go as black as oblivion.
How she carried herself  in a don't care fashion 
She sauntered towards me and whispered "meet me my room 10 minutes "
Something about her voice was different then before .
I walked up the stairs wandering  what (yn) would need .
I knocked on the door .
She slowly came to the door with streaks of saltiness under her eyes .
"Come on in cas "
Her voice was groggy and hoarse.
She strode to close the door  her back smashing the back of it.
"Cas we need to talk "
I saw more tears pricking  her eyes .
"My dad's been requesting my presence and wants me to go home I don't want to though because  I love  you and I want to hunt with the Winchesters He says if not he wants  war because I disintegrated  the blade of kain "
She stared in my eyes tears streaming down her face .
I held her in a firm embrace .
"I will protect you "
I said.
she got out  of the hug and  showed me her arm were a mark .
It was different  it had a halo  with horns .
Then she gripped the collar of my trench coat and   said "cas sometimes most of the time  I have dark times   but you cas are definitely the light " she grazed my cheek with the back of her  hand .
"Well I'll help you no matter what "
I said  .
I grabbed (yn) hand tracing the lines .
"I love you too "
(Yn) enveloped me in her arms crying on my shoulder .
I ruffled her hair and I hushed her sobs kissing her hair .
When Sam and Dean barged in and she stared up wiping the tears away .
"Well boys we've got a truck load of stuff to do including  a mighty fine demon "she patted the Winchesters shoulders .
And skipped down the stairs .

The very nature of him it's facinating.
His voice, his mind , his looks ,his eyes.
His trench coat is etched  in my  memory.
It's scent of petrol and nature and blood .
His kiss is soft yet passionate;rough yet smooth ;sensational yet calm.
His embrace is very meaningful  and special .
I feel safe encapsulated in his onyx wings.
My imagination drifts to other thoughts .
His topless chest ,his trench coat on the floor our legs entangled .

Castiel pov
I can't stop thinking about her .
Whatever I do to distract myself  I just can't separate the thoughts .
I might ask Sam and Dean .
But first I need to tell them What (yn)
Told me .
