Walking quietly from one door to the next, Dean checked them and the windows. Everything was intact and secure. He made his way to the service entrance, stepping outside for some fresh air. Slight movement in the shadows had his hand immediately reaching for his gun. In the next second the shadowy movement resolved more clearly. "Hello, Dean."
He relaxed a small amount, he’d always be wary around this visitor. "We have it as done as it’ll get. There’s really only one sticky spot."
The figure in front of him nodded, but said nothing.
Dean was hit with a flash of inspiration so suddenly it nearly shoved him off his feet. He narrowed his gaze, studying his visitor closely. "You can help. Sam and I, we can’t do this alone, we need help. Your help. I’ve never asked anyone for anything like this before, but I think I have an idea, if you’ll help us. We’re out of options and have no where else to turn."
Nodding slowly was the answer Dean had hoped for. He blinked and was alone, Dean’s visitor had vanished.

We've done it. Finally! The last episode of Season. Enjoy!
