Note: Inspired by an amazing gif-set on tumblr where Cas isn't an angel but a demon. This is my take on that AU, we'll see where this goes, yeah?
Jimmy Novak was intended for the angel of the Lord, Castiel. His entire bloodline was designed to manufacture the perfect vessel for Castiel's Grace; for him to use for holy purposes.
Upon falling from the Divine Fields, Castiel no longer had the right to any holy missions, nor his vessel. While Castiel was, technically, a demon now, the Fallen Ones could not pick a vessel as easily as a demon could, nor could they force entry. They still needed permission. And what human would give permission to a messenger from Hell, sent to Earth to ensure the beginning of the Apocalypse? Certainly not a sane one.
Castiel was not below lying to get what he needed for this mission, however.
"I come to you with the urgency of a holy mission, Jimmy", Castiel says, enforcing dark power into the words. Jimmy shudders under the force of it, looking all around him to try and pinpoint the source of it, but Castiel stays cloaked. "Will you help me?"
"But why me? What help can I be of for you? I'm just a man," Jimmy says.
"You should not think so lowly of yourself, James Novak," Castiel says. "You are special amongst men, a unique creature, chosen for bigger purposes than you can imagine."
"But my family..."
"Tell me, Jimmy, do you believe in God?" Castiel interrupts.
Jimmy nods. "Of course."
"Then believe me when I tell you this; in the name of the Father I swear, no harm will come to your family."
The words slide easily from the fallen angel. They don't even cause a twinge of pain. God doesn't care, either way, so why should there be any wrath awaiting for lying in His name?
Jimmy swallows. "Then, yes, Castiel. I will help you."
Castiel promised no pain would be inflicted on him. Castiel promised rewards for his servitude. Castiel promised safety for his family. As the dark smoke pushes its way down Jimmy's throat and lungs, tearing flesh and tissue on it's way down, and he connects to the angel - the demon - he knows none of the words Castiel spoke were true, and he screams, and screams, until his mouth is silenced by a will which is not his own.
And after, he continues to scream within the confines of his own mind, which have now become a prison.
