Castiel has been keeping Dean's daughter Mary a secret from him but when Mary's mother is taken, Dean finds out about her. After the death of her mother Dean has to become the parent he never wanted to be.

Castiel

"Castiel how nice to see you again"

I enter the house, I decided to knock on the door to be allowed to enter

"hello Amanda" she smiles

"how are you? You haven't visited for a few months"

"I have been busy" she nods

"so how is Dean?"

"the same" she smiles

"Mary is in the living room"

I nod and walk in the other room to see Mary Winchester, the only child of Dean, my best friend,

"she's looks more like him with every day"

I nod, she has his green eyes and dark blond hair, but she looks more like her mother

"Castiel!" she says happily and jumps into my arms

"you are going to be four soon so I thought I would visit"

she hugs me tightly

"thank you for visiting Castiel" said Amanda leaving the room

"I drew you a picture"

I walk her over to the table and set her down, she hands my the picture, I look at it, it is very good for someone her age, I believe she will be an artist when she grows up

"thank you Mary"

I kiss her forehead, as guardian to the Winchester brothers and I being their friend I have taken responsibility for this little one Dean never meant to create, that has always amazed me about humans. How they ever plan on having children but they are born anyway.

"Castiel are you coming to my birthday party next week"

I shake my head

"no little one I have other duties to do"

being here in Lawrence where it all began makes me feel odd

"okay but will you come see me soon"

I nod

"of course little one"

she hugs my leg, I pet her head and pick her up, such a beautiful little girl

Hey Cas we could use your help

I sigh

"I have to go little one"

she nods "I love you Castiel" I rub her back

"I love you too Mary"

I walk into the kitchen

"I have to go goodbye Amanda"

she smiled "goodbye Castiel"

I walk out of the house and transport back to the bunker

"hey Cas" said Dean

Mary is really beginning to look just like him

"what do we have?" I ask

I wish I could tell him about Mary but the day I first met Amanda she asked me not to tell him. She didn't want to complicate his life, she is a very kind woman.
