This one was a tussle. Whew! I wound up bringing in DEATH from the Discworld as an opposite number for my favorite cranky Southern doctor. (I'm not at all sure of his voice - Disc!fic is a thing I generally don't even try - but... *shrugs* Either it's good or it isn't.)
Fandoms: Star Trek: TOS, Discworld
Characters: Dr Leonard "Bones" McCoy, Death
Prompt:
#3: Present
YOU CAN'T SAVE HIM, YOU KNOW.
The slim, blue-clad doctor glares across the room. I can try.
IT'S HIS TIME TO GO.
Blue, so they say, is the color of eternity. Death's eyes are blue.
So are Leonard McCoy's.
I don't tell you how to carry that scythe, he snaps; don't you go tellin' me how to do my job. What kind of a doctor d'you think I am, anyway?
A STUBBORN ONE, Death admits wryly. BUT EVEN YOU MUST SEE THAT EVERYTHING HAS ITS APPOINTED TIME TO DIE.
Doesn't mean I'll just step back 'n' let it. Now scram.
