Sam's POV
The sunlight streamed through the curtains as morning sent me my wakeup call. I squinted and lifted my free hand to shield my face from the sudden bright light blinding me.
Turning my head slightly i saw Sierra, still fast asleep, with her arms loosely hanging around my neck and the front of her body on my forearm.
A small smile crept onto my lips as my eyes traced over her, her face so peaceful and beautiful, i wish i could've stayed here for ever. But i knew i couldn't.
I slowly and carefully, withdrew my arm from beneath her body so as not to wake her from her sleep. She shuffled slightly and let out a small breath as she rolled over to face me, her eyes still closed.
I had to hold back a small laugh as i stood up, looking down on her lying on the bed, her hair a like a mane in front of her face and her jaw half open, her tongue lolling slightly in her mouth.
Silently i changed into some fresh clothes and ran my fingers through my hair in order to calm the mess of bedhead i was now possessing.
Once i had pulled together all my things into my bag, i turned back to Sierra's motionless figure. I moved over to her and planted a kiss on her cheek, not wanting to leave her but knowing i had to.
"I'm sorry," I said softly as i made my way out the door and slowly drew it shut behind me.
Moving quickly down the stairs i came to greet Bobby, Dean and Cas stood waiting for me.
"You sure you want to leave her here?" Bobby asked me, his facial expression screaming disapproval.
I nod curtly and exchange a brief look with Dean who, when his eyes meet mine, give me sympathy and understanding. I'm grateful for that.
"If you would like i can wait with her until she wakes up, it may be safer." Cas suggests and i hesitate before agreeing and thanking him.
Then, i follow Dean and bobby out to the impala. We were going to Detroit. He always said it would happen in Detroit.

Sierra's POV
It was almost an instant feeling when I woke up, that something wasn't quite right but i couldn't place it.
I opened my eyes slowly, letting my vision clear and focus on my surroundings. Sam was gone, but i didn't doubt he was probably downstairs with Bobby or Dean so i didn't let that worry me too much.
Grunting slightly I pushed myself into a sitting position, and untangling myself from the sheets I allowed myself to observe the room a little more.
There was definitely more stuff in here last night, or at least I had thought there was. Frowning, I got to my feet and moved to the door. The house was silent.
I could feel my stomach twisting into knots as I made my way across the landing and to the stairs where I saw no sign of anyone.
"Sam?" I called, leaping down the staircase, hoping I'd find them in the kitchen or the living room.
"Dean?" No answer, "Bobby!"
The panic began to rise in my voice, what if they were hurt or in danger? Why the hell would they leave me here on my own?
Suddenly it came to me. I knew exactly where they had gone. Detroit.
I swore under my breath and lashed out at the wall with my fist, pain erupting from my hand as I felt the bones crunch upon the impact with the brick.
I let out a cry of pain, clutching my hand to my chest and falling backwards to the ground.
"SHIT" I screamed, a white hot rage rising in my stomach, tears stinging my face as they rolled down my cheeks.
"Sierra is everything alright?" A familiar voice came from behind me.
I spun around quickly on my knees and looked up, my eyes locking with Castiel's.
"How could you let him do this?"I hissed through gritted teeth.
After a few seconds of Castiel simply staring silently in response, I let out yet another yell of anger and slumped sideways into the wall.
I was crying uncontrollably now, but despite this, I looked up at the angel, my eyes pleading with him.
"Castiel, I need you to help me, take me to him" I begged, "Please."
Castiel stared at her for while, contemplating whether or not he should do what the girl was asking.
He hadn't fully agreed with sam's decision, he still doubted whether or not any of their plan would work. However, he had made Sam Winchester a promise, one he wasn't sure he could break.
He looked down at the girl, crying on his knees before him and he felt something inside him soften slightly. Whether it was compassion or sadness or empathy, the angel was unsure but he knew he felt something.
Castiel tilted his head, confused by the feelings he suddenly felt.
He knew he had to help her.
"I can't do anything to help you, I'm human, currently at least," Cas began and he saw Sierra's face fall, "But I might know someone who can."
--
About an hour later, Cas had managed to form a summoning spell for another angel. Someone who he believed would be able to help them.
Castiel lit a match and threw it into the bowl containing the ingredients to summon him. A white flame flared up in the bowl and Sierra winced at the brightness of the light.
When her eyes reopened, a tall man with styled blonde hair stood before them, hands on his hips.
"Seriously Castiel?" The angel began, looking over to Cas, "I was in the middle of a rather lovely-"
Sierra's eyes met with his and he stopped.
"And who's this?" He asked, his eyebrows raised as he began circling around her, looking her up and down.
"Balthazar this is Sierra," Cas began, "and we need a favour."
