Five Disturbing Dark Fics
1) Twitch by spuzz: This is not fluffy Spander in any way, shape, or form. Instead, what you have is a portrait of Spike going off the rails and taking Xander on a very bad ride.
2) Innocence (the If You Love Me Remix) by snowpuppies: We were told how evil Angelus was, but we never really got to see it on the show. Snowpuppies has stepped in to rectify that lapse with a look at what would have happened if Angelus had shown us who he really is back at the apartment with Buffy.
3) Last One Standing by kallie_kat: A dark classic. Angelus has taken almost everything away from Willow... but he's working on the one thing she has left. Her mind.
4) Does the Mouse Scream by snogged: Angelus has some...fun with Fred. This one's won awards and for good reason.
5) The Perils of Fantasy by salustra: Yes, Angelus is at it again... and he's got Cordelia right where he wants her. *shivers*
