Blair Witch- Fog Kills Fellowes

"Eat my heart, huh?" Crawford reached down, pulled off his belt, and tied Fellowes's hands with it. "All you're going to be eating is prison food."
Now it was Fellowes's turn to howl in frustration. He writhed underneath Crawford, trying to throw him off: his body was one long, corded muscle.
Crawford leaned into him, pressing his weight down.
It occurred to him that quite probably he was going to have to knock the man out to get him safely back to town.
Wouldn't that be a damn shame.
"Get off of me!" Fellowes yelled.
Crawford grinned.
And the wind, which had died out almost completely, began to blow again.
Fellowes stopped struggling. "No. No! Okee, I do not--I can beat this man!"
Fog rose on the rock. The wind howled.
"No! Okee, don't!" Fellowes started to struggle again, if anything more frantically than before.
The fog swirled around the two men like a thing alive, darting this way and that. It seemed to settle for a moment around Crawford's leg, where
Fellowes had cut him, and it--
Squeezed.
Crawford gasped.
Then the fog was off him and on Fellowes.
"No!"
The man's scream turned into something wordless. His body tensed--
--and then he stopped struggling and went suddenly limp.
The fog lifted. The wind died.
Crawford rolled Fellowes over.
Blood dripped from scars freshly carved on his forehead.
...

Crawford sat on the rock.
The night sky above was pitch-black and full of stars. The moon shone brightly; the clouds had all cleared.
Fellowes lay before him, his eyes wide and unseeing.
Crawford was alive. And Fellowes was dead.
