Castiel Novak is a serial killer whose ultimate goal is to make sure everyone knows exactly who he is. His face is seen by every single camera he goes by and yet he is elusive as the night. Dean Winchester is an assassin who has the ultimate goal to stay hidden. He is known as the Elusive Knight: the deadliest assassin who is in and out. When he's done, the only thing that lets people know that it was his work, was a single black-dyed Lilly pinned to the breast of his targets. But when Dean is finally caught on camera by none other than his own brother, his life is thrown into chaos. When Dean is given the assignment to assassinate none other than Castiel Novak, the Elusive Knight sees his chance to make sure that Cass knows he's after him. Castiel is finally able to see who the Elusive Knight is, and he definitely likes what he sees. When he is alerted by none other than Dean himself by camera, Castiel chooses his next victim. With both of them after each other, communicating through the cameras that follow them, they each try to outsmart the other. But as they learn more about each other, after studying each other, they grow more interested by the other. When they finally meet, will they be able to carry out what they set out to themselves, or will fate bring them together in a different way?

Sequel to the summer camp AU Sam, Dean, Gabriel and Castiel all went to a camp on the summer of 2013. They were in a cabin together, became friends, and eventually became closer than that.

But when Dean and Sam left, and Gabriel and Castiel a few days later...there wasn't much hope. They said they'd fight to find each other...but when all the odds are against you, there's no way you can win. So what they did instead was wait. They waited until the winter of 2018.

Castiel and Dean have grown up together since they were four years old. Now the two have become completely different from one another, one being a punk and the other a jock. Yet nothing stops the two from being the best of friends. When a drunken night in a camping tent turns their whole relationship upside down, will their friendship survive? [FURTHER DESCRIPTION IN FIRST PART]

On principle, Castiel never works with new and “up and coming” talent. But just this once, he decides to make an exception with Dean Winchester, who he ends up bending all his rules for.

It's 1995, and Castiel's high school years are destined to be difficult: home-schooled until eighth grade, he is awkward, shy, and socially inept. The weird kid with the funny name would rather isolate himself and draw in his sketchbook than deal with the constant bullying he faces every day. Things only get worse in his junior year when he excels in home economics class, leading the captain of the baseball team, Alastair, to start taunting him for being gay. Then new student Dean Winchester arrives at Flour Bluff High School, sharing many of Castiel's classes. Castiel has seen his type before -- handsome, athletic, arrogant, and sure to be the most popular kid in school. But Castiel eventually learns that he and Dean have more in common than he thought, and they form an unlikely friendship.
