[janie-tangerine.livejournal.com]

Title: Fire Of Unknown Origin
Rating: R
Pairing: Jacob/Castiel
Words: 1565
Summary: Castiel had told him to pay attention, it was, as humans sometimes said, like playing with fire; and Jacob had smiled his bright, angelic smile and said that if he got burned, it'd have just been fate.
Spoilers: er, general S4 for SPN (if you know who Castiel is then you're safe) and The Incident (5x16/5x17) for Lost.
Disclaimer: sure as hell they aren't mine, otherwise I wouldn't have lost half an hour between Lostpedia theories and angel lore. And I'm not rich enough, anyway.
A/N: originally written for the Porn battle for the prompt fate. Title stolen from Patti Smith. Entering for lostfichallenge #95, crossover. Using also for sacred_20 #15, fate, and au_abc, x-over.

(Once, Jacob wasn't his name. That was before he fell, but after the Fall. )
