Here's some more information for your mind to crunch - try and work out what happens next - would love to hear your theories :P
"What do you want?" She demanded struggling to free herself from the invisible grip to no avail.
"Just you, darling little Sammy is just a bonus" he smirked.
Sam and Dean looked at each other confused.
"You are not going to get your hands on him...ever" she said struggling harder more determined, trying to overpower him with sheer will.
"I wasn't really asking for permission sweetheart. First I'll have to deal with you three...but you know how it goes, ladies first" it said winking at her.
"Bring it" she said meaning every word.
He contracted his hand, accepting her challenge. Her insides felt like they were in the palm of his hand.
"You'll...never...get...him" she choked.
"We'll see" he said clearly not convinced.
Her body suddenly went lax.
"We'll let her bleed out. Who goes next? Dean of course, wouldn't touch big Sammy, my father wouldn't like that"
He was walking closer to the boys but he suddenly could go no further and Sam, Dean and the woman were released from his grip and unceremoniously fell to the floor with a thud.
Dean went to the woman and saw a pool of blood growing around her.
With her head in his hands she spluttered trying not to choke on her blood and failing.
"Devil...trap...take...that...bitch" she said before coughing out more blood. (A/N - the devil's trap is actually underneath the carpet floor, so clearly she is no newbie)
The baby began to cry.
"Sammy" she said picking herself up from the floor.
"Hey, take it easy, you've lost a lot of blood"
"Sammy needs me" she said trying to push pass Dean and failing.
"Sam you take care of this douche?"
"Yeah, go", Sam stepped forward and began to exorcise the demon.
Dean moved out of her way and waited for her to lose her footing to support her weight. Being a hunter he knew she wouldn't ask or take help if she could avoid it.
He took her to where the baby's cries could be heard.
She slipped out of his grip and used the baby's crib for support.
"Everything's ok Sammy, go back to sleep" she said smiling once his eyes closed.
"Quite a kid you got there. Now let's get you cleaned up"
Dean came up next to her and helped support her.
She told Dean to help her into the spare room. He helped her to lay down on the bed.
Sam joined them to let them know it was done.
"This doesn't look good" Sam said looking at the damage the demon had done.
"He's my brother", "the baby" she clarified, changing the subject.
"Any other family?"
"A family of hunters" she laughed painfully, "if only. Just me and Sammy left. I think you might want to call Castiel" she said on the verge of passing out.
"How do you know about Cas?"
"You could say we have a history. You get him, he can clear up all the answers, Dean" she said looking at the silver band on his finger.
"Who are you?"
"Soon" was all she would say, eyes growing heavy.
"I think you're going to have to go to hospital"
"Call Cas, he'll know what to do" was all she said before she passed out from blood loss.
Dean flipped open his cell and speed-dialled Cas. He said the address and he flipped the cell shut, knowing he was already on his way.
"Can you do anything to help her Cas?" Dean said as soon as the Angel appeared by her side.
"I'll try" he said in his serious voice.
He closed his eyes and concentrated hard with his hand over her heart.
"I've healed her internally" Cas said clearly drained somewhat.
"That'll have to do" Dean said.
Cocky bugger wasn't he (the demon).
Who the hell is she? What has she got to do with ending the apocalypse? How does she know Castiel?
A/N - Stay tuned. Same rules as last time, a week maximum, reviews speed up the next post.
