Hello Fanfiction, it's zammi. This is my firt story, please tell me what you think. This is supposed to be set sometime about midway through season 10. Dean still has the mark of Cain. Read, review, flame, hate, whatever, just do something!

Chapter 1

Dean woke up to a blaring rendition of Lady by Styx, to which he responded with the Winchester glare. Sam patted him on the back and countered with a simple "your boyfriend is here." Cas stood awkwardly outside the Impala where Dean and Sam where bickering. Dean turned down the radio and casually slid out.

"What have you got for us today, Cas? Angels? Demons? Ghosts? Mutant Parakeets?"

"To my knowledge, there have been no recorded incidents involving hunters and mutated avians."

"Not the point Cas. What is it?"

"I believe someone is imprisoning or killing angels."

"Oh. Any idea who or why?"

"I hear they make good boyfriend material" Sam butted in.

He was met by an angry look and a confused stare.

"Where do you believe the angel-napper is hiding out?" Dean asked.

"Somewhere in the vicinity of Denver. I cannot see the area from heaven, and no angel known to frequent that area has been heard from in over a week."

"OK. We can be there in less than three hours." Dean said, already planning out the route in his mind.

"It would be more efficient for me to fly there"

"Sorry Cas, but you are sitting this one out. Thanks for the job, but flying an angel into the angel version of the Bermuda Triangle is not a good idea."

After contemplating triangle of Bermuda, Cas responded with righteous gusto: "An angel may be responsible for these disappearances, and if so it is my duty to protect my brothers and sisters. I have hunted with you before, and on more than one occasion, saved you life. I am coming."

"If this is an angel, won't they sense you zapping in? You know, Angel sonar and all? And more importantly, whoever this is taking out angels. You are an angel. Go take a week off and work on your tan. You need it." Dean quipped.

"I am uncertain as to how skin tone effects my performance as a hunter. However, I can minimize risk of detection by riding with you to Denver. As long as I do not use angelic powers, I should not show up on 'angel sonar.'"

"I don't know Cas. This just seems like a bad idea."

"How many times have you entered a trap know it was a trap?"

Dean and Sam share a long, tense, look and Sam shrugged and said "He's right, you know."

"Hop in Cas" Dean sighed, defeated.

Two and a half hours, six Chick-O-Sticks, an argument over whether or not Redbone was from Texas or California, and a discussion over the feasibility of a killer mutant parakeet later…

"Cas, how do you know someone is responsible for this? Could it just be residual turmoil in heaven from the war?"

"You might call it a gut feeling, intuition, a hunter's insight, a sixth sense, a hunch, healthy suspicion-"

"We get it, Cas, we get it." sniped Sam.

Dean stopped the Impala by an older building in Aurora1 and asked "you picking up anything Cas? Any vibes, feelings, senses,-

"Not you too! Get a room!" cried Sam.

They began to explore the suburbs, splitting into teams of two. Dean insisted rather forcefully that he go alone, and that Castiel and Sam go together. With a knowing wink, Sam walked off after Cas, leaving Dean to not admire the view from behind.

Dean walked away from the neighborhood, toward a small forest. He wandered through the trees, looking for anything out of the ordinary. Dean was an experienced hunter, and he could tell when things were normal and when things were supernatural.

After a fruitless search, the plaid-clad hunter began to trek back to the car. He was about to call Sam's cell when he saw a blinding flash of white light, and heard a shout. He sprinted towards the sound, and got their just in time to see Castiel, lunging away from the source of the light. Dean surged forward, trying to grasp Cas's sleeve. Years of combat- trained instincts kicked into high gear. He watched as the ground fell away from underneath the light, and the ravine spread out, quickly engulfing the ground beneath the angel and the human. They collided as they fell, Dean still holding on to Cas's arm. The next moment they were swallowed by the earth and thrust into darkness.

1Aurora is a suburb to the East of Denver.
