Vermifuge by aeraecura
Freed from the Fresh parasite's control, Sans finds himself in an Underground that isn't quite his own. He takes what's been given to him as best he can. (Or: a slightly gentler alternate ending for a character with a disturbing fate, as written by a canon purist who feels no love for AU content. With apologies to Hiroyuki Owaku.)
