Their ride was quiet, each in their own thoughts, as Dean pulled the car next to the bunker door. Mary exited the car and walked with Dean to the door. He opened the door and led her into the home of the Men of Letters.

"Dean!" Sam yelled from the kitchen, hearing the sound of feet on the metal stairs. He came out of the kitchen into their meeting space before stopping when he saw Mary.

"Sam," Dean said, standing beside her. "This is Mary. She-" He stopped, unsure what to say. Mary immediately smiled and extended her hand as she walked towards Sam.

"Hi, I'm Mary. It's nice to finally meet you. Sorry about Jess and Amelia, they sounded like great women." They shook hands, Sam's eyes doubling in size. He looked at his brother who shrugged and rolled his eyes. Sam pulled his hand away a little too quickly but Mary didn't seem to mind. She looked back at Dean.

"Who is this?" Sam asked, finally finding his voice. She turned back around, her brunette hair bouncing around her oval face.

"My name is Mary. I don't like to repeat myself so before we go further," she turned back to Dean. "Shall we call Cas and I'll tell you everything?" Dean nodded and went to find Cas as Mary and Sam took seats around the world map table. A few moments later, Cas and Dean returned to them and took their own seats at the table.

"Start talking," Dean said.

"Such a demanding tone," Mary said, unsuccessfully trying to lighten the mood." Fine. A few months ago, I was approached by a man and woman. He said his name was Chuck and her's was Amara." Dean looked at his brother and best friend before turning back to Mary. "He said that they had made a mistake and wanted to help set it right. Eventually he said he was God and she was his sister. They wanted to give you a gift to apologize for what they did."

"And that gift is what?" Dean asked.

"Me," she said. Dean scoffed at her claim. "I know how that sounds, but I'm telling the truth. Chuck gave me his books and said they were really biographies of you all. I've spent the past few months reading about you all and your cases. That's part of why I know so much about you."

"What do you mean 'part'," Sam asked. Mary took a deep breath.

"My full name is Mary Singer." Both boys straightened in their seats.

"Singer," Dean said. "As in Bobby Singer?" Mary nodded.

"Bobby is my uncle. His father had an affair and my grandmother gave my father his last name. I met my uncle about four years ago. He wasn't happy about the situation, he never liked his father. We did a DNA test and confirmed we are related. He's been training me to be a hunter since then." Dean's head rocked back again.

"So now you're a hunter."

"Oh honey, I'm a lotta things." She smirked at him, her eyes glittering. He cleared his throat and shifted in his seat. "Well, this has been fun. Cas?" She turned to the silent angel. "Would you like to take a peek into my memories before I find a room to stay in for the night?" Castiel flicked his eyes to Dean who nodded. Cas stood and walked behind Mary's seat, putting his hands on either side of her head an inch away. The brothers watched as Mary closed her eyes and Cas's hands glowed a soft yellow. After a few heartbeats, Cas dropped his hands and stepped back.

"Take the room on the second door to the left," Dean said. She thanked him and wandered towards the rooms. The boys waited until they heard the door click.

"Dean what the hell?" Sam said.

"What?" Dean said. "What do you want me to say, Sam? I met her at the bar, she knew a lot about me, about us. Should I have walked away?" Sam closed his mouth and let out a breath through his nose. "Cas, what'd you see?"

"It's just what she said. Chuck and Amara. Meeting Bobby and the DNA test. I didn't see any hidden information."

"Okay, so now what?" Sam asked.

"Tomorrow, I'll call Bobby. Now, I'm getting a beer." Dean pushed himself up from the chair and headed to the kitchen.

"Sam," Castiel said. "Keep an eye on her. I trust what she said and what I saw, but I don't trust Chuck." They nodded and went to bed.
