I didn't think I could actually do this, but then I remembered one last story, so, for Halloween, the spooky/scary/horror stories I've written -- and there are very few, out of something like 100 stories I've written:
The Final Fate of Bootstrap Bill: in three parts, linked at the bottom of each story. Moonlight & Memories, Jack Sparrow Remix, and Full Fathom Five Variant. Only canon-compliant through the first movie, but I still had fun working out what really happened to ol' Bootstrap.
Divergence: Firefly, written before the Big Damn Movie, but may remind people of some of the final scenes there.
Expectations: Angel, Season 3 - Darla and her little bundle of anticipatory joy.
Myths & Shadow Plays: Spike, post "Helpless", Season 7, stuck in the basement of Sunnydale High.
End of the world (as we know it): Forever Knight/X-Files crossover, post-alien-invasion, Natalie & Doggett.
Urban Myth: Ghostbusters-- and God, this one is old. 1992. Ray picks up a hitchhiker on a rainy night.
There. Six, when it's supposed to be five, but that may be all the creepiness I've committed, so: Happy Halloween, everyone!
