Sam was reading through some old cases that he had found in the library. It was his turn to watch their mystery angel, who was still unconscious. They held her in the dungeon, surrounded by a ring of fire. He was confused though, angels don't sleep, and they don't need to. So why would she be like this?

He was still pondering over this when he saw something move out of the corner of his eye. He turned to see that the girl was standing, eyes wide, looking at her surroundings. He shouted for his brother while watching her. The girl was short with long dark brown hair and hazel eyes. She was calm, considering that she was being held captive.

"Well, well, well, looks like our sleeping beauty has finally awoken," Dean smirked as he walked into the room.

"Sam and Dean Winchester," she smiled, "Its nice to finally meet you. Though I was hoping it wouldn't be like this." She looked down at the holy fire at her feet.

"Yeah, well, you're not getting out until you tell us who you are," Sam demanded.

"I'm Grace," she stated.

"Grace?" Dean snorted, "An angel named Grace." He kept laughing until Sam elbowed him in the ribs and gave him a look.

"What?"

Grace looked at him with a serious expression, "I'm no angel."

"Oh, yeah," Sam proclaimed. "Then what are you?"

"I'm just Grace," she said honestly, but the boys didn't believe her. Why should they? When they found her she was in a ring of fire and she flung a demon across the room. Dean was just about to say something when they heard a thud come from upstairs.

"That must be Cas," Dean said. He then turned and yelled out the door, "We're down here, Cas!"

"C-cas? Do you mean, C-castiel?" she stuttered. Her eyes went wide and a quick look of panic crossed her face.

"I take you've met him before," Sam claimed as a blued eyed man wearing a trench coat walked into the room. Grace immediately dropped her head. But it was too late, he saw her and froze.

"I thought you were dead," Castiel retorted.

Grace let out a nervous laugh, "I guess you didn't wish hard enough."

"No, you should be dead. That wound I left you should have killed you," he pressed and Grace shrugged.

"What the hell is going on," Dean shouted.

Castiel looked at Grace, urging her to explain. But she kept quiet, confused.

"Wait, hold up, so you're not going to kill me," Grace questioned.

"No, the only reason I tried to all those years ago was because I was ordered to." Cas explained.

"Oh."

"Is anyone going to tell us what is going on," Sam asked frustrated.

Castiel walked over to the supply cabinet, picked up a jug of water and put the fire out and looked at Grace intently. Grace sighed and began to talk. "A few centuries ago angel and a human fell in love. He even chose to fall to be with her. They lived happily for a few months, until the angels came for him. He knew he was going to die, so he gave her the only thing he could. His grace."

When she finished telling her story it was quiet. The two brothers just stared at her, stunned. "So you are an angel," Sam replied.

"Not fully, no. I'm sort of between an angel and human."

"Damn, you're pretty hot for being as old as you are," Dean joked.

At this Grace rolled her eyes. "Just remember this, Dean; I can put you on your ass in a second," she said, earning her a chuckle from Sam. "Oh, and by the way, how did you find me? Don't get me wrong, I'm thankful for you saving me, but I'm not the easiest to find."

"A demon named Crowley asked us to get you," Dean answered.

"Crowley?!"
