This starts off in the past with the ending of ep 13 season 2, Houses of the holy.

This story will have Destiel in it later on, just a warning in case you know, you don't like that kind of thing.

Dean walked through his and Sam's motel door after seeing an attempted murderer get shish kabobed through the stomach. Sam was putting away his clothes, "How was your day?" Dean rhetorically asked.

Sam didn't acknowledge Dean, as the elder walked slowly toward his brother. "You were right, it wasn't an angel…it was Gregory."

Dean shook his head and reached for his flask, taking a swig and then holding it out to his little brother, knowing it would help him calm down a bit. Sam was hesitant but ultimately took the silvery object, trying to dull his sorrows at least a little. "I don't know Dean, I just…" Sam sat down on the old spring motel mattress, "I wanted to believe…so badly in it. It's so damn hard to do this, what we do. All alone ya know and…there's so much evil out in the world, Dean, I feel like I could drown in it. And when I think about my destiny, when I think about how I could end up…"

"Yeah well, you know what? I'm watching out for you." Dean sat across from Sam on the identical twin bed.

"Yeah, I know you are…but you're just one person Dean." The boys looked at each other sorrow and pain filled their eyes. Dean knew it was true, he is only one person but everyday he wakes up and looks at his baby brother and hopes it's enough. Hopes that he can do what his father told him to do, protect Sammy. "And I needed to think that there was something else watching too, you know Dean? Some higher power, some greater good…and then maybe…"

"Maybe what?" Sam stared at the wall with a sad smile gracing his features, small tears welling up in the eyes.

He looked to Dean, "Maybe I could be saved." Dean shut his eyes; he just wished his brother thought that he was enough to save him. He felt like he let John and Sam down.

"But," Sam laughed, "I just clouded my judgment and you're right we gotta go off what we know. What we can see, what's right there in front of our own two eyes."

As Dean was about to tell Sam about the now dead guy he was pursuing earlier a wired flapping noise was heard, like bird wings, and suddenly a man of his early thirties was standing in the middle of their shabby room. "Hello Dean."
