Prologue:

Gabriel sat, pleased at his new plan that was laid out in front of him. The Winchesters and his dearest brother may think he's dead, but that doesn't mean that he can't have some fun with them.

He smiles at his work once more and rises from the couch, eating a newly formed candy bar while laughing at his brilliant ideas.

Castiel will not be pleased. Neither will Dean-o or Samsquatch.

But does Gabriel care?

Of course he doesn't; he's the trickster.

Let the fun begin.
