If you don't mind a self pimp, I have a Gen fic (could be slash if you wanted it to be) called Running Out of Time (http://authoressnebula.livejournal.com/tag/running+out+of+time), four small parts, and it's finished. It's post Everyone Loves a Clown, and what I really wanted to see happen to the boys.

Also, I'd like to point you in the direction of these great (finished, gen) fics:

Residue by Buffyaddict (http://www.limp-sam-fanfiction.com/buffyaddict/residue.html) (post Born Under a Bad Sign)

The Darkness Between by Faye Dartmouth (http://www.limp-sam-fanfiction.com/fayes/darknessbetween.html) (post Shadow)

In The Twilight by Darktales (http://www.limp-sam-fanfiction.com/darktales/inthetwilight.html) (post Devil's Trap, goes AU after the car crash a bit)

Unanswered Calls by Onari (http://www.fanfiction.net/s/3030974/1/Unanswered_Calls) (post Provenance, alternate ending of sorts).

Good search; I approve. ^_^
