This was a moment in time that never should be reached.
Castiel glances at the male - the demon tied down in front of he and Sam. Blood stains of markings surround the abomination on the floor. A single chair, backed by steel metal. Engravings mark the wrist and ankle cuffs.
Dean Winchester snarls at them, and Sam pulls out a needle.
"This is for your own good, Dean." His brother says, just as Castiel completes a sigil on the wall. Dean Winchester, about to be cured? Most of Hell would try to put a a stop to that happening.
Abuse and cries and swears and threats are thrown out over the next couple of hours, but slowly, slowly (Castiel scarcely believes it) Dean’s eyes soften. Beads of sweat form on his head. The scowl disappears.
Castiel knows, and Dean knows, but Sam is still there, a blinking flashlight of hope.
"We can cure you, Dean. We’re nearly there."
Dean takes moments to reply. Castiel shakes his head, and moves in before.
"No, Sam. You need to let it rest."
"Sammy, I… You need to let me go…" Dean finally manages out. "The mark… it…"
"Dean. Give it to me."
Dean stares. He shakes his head.
Castiel, for now, says no more.
Another injection later, and Dean has been begging for the end of his life for the past 20 minutes. It’s agony to Cas’ heart. Dean’s pleadings suddenly stop for a moment.
Castiel looks up and at Dean, whom he is sure has tears in his eyes. Dean still isn’t cured. Not with the mark.
"Cas, you can do it. Put an end to… to…"
Castiel stands there, and gives one shake of his head. “No. I can’t.”
"Cas, please, I can’t… I can’t be this…”
Dean flexes his hand, and something within Cas spots the opportunity, and dives for it.
He grasps Dean’s hand and almost immediately, pains sears through Cas’ broken, stolen grace, and blinds his senses as he hits the ground.
He sees the mark on his arm. He feels it.
It feels… It feels…
He uncurls himself, and stands up slowly. He looks at the Winchesters.
Castiel grabs the first blade. He hears Dean weakly shout something.
It’s been one month.
Castiel is waiting.
