Some things you just feel.

Relying on each other brings the slayers close

A race, struggle to stay alive until dawn.

A new world is born out of the death of the first.

Faith gets a little revenge for Buffy's moments with Spike.

The Slayer faces her biggest nemesis to date.  Buffy centric with glimpses of Faith.  A lost slayer variation.

Buffy, lost in life, embarks on a journey of discovery, looking for a place to belong.

Buffy has vanished without a trace. Faith is among those sent to track Buffy down. But is she ready to find Buffy? And is Buffy ready to be found?

Set after Season 7.

After Twilight is beaten, the world's left without magic and what's left of the slayer army and the Scoobies has scattered. Giles is dead, and he's left most of his will to Faith.

Based in Britain, and rehabilitating Angel, Faith decides to build a new Watcher's Council, and to work to try to back hope to the world. It's hard to see if she'll manage.

Alt-Season 9.

"Been a while, V. How long did it take you to think of your opening 'intro-pun-ction'?"

"Ha ha, good one! You know me. I love to make an entrance," Buffy said cheerfully, standing a few feet away from Faith, looking pale and wearing all different hues of black. "And it has been a while. I thought about paying you guys a visit. But I had a feeling you wouldn't have invited me in."

"Can you blame me?" Faith said, feigning playfulness. "If you were me, you'd have done the same."

"Touché," Buffy said with a disarming smile. "I'm sure that's what I would have wanted."

"Just carrying out your will, V," Faith said, surprised at how steady her voice came out.

Or...

The one where Buffy quite literally becomes a "Vampire" Slayer, and Faith must eliminate her. 

Faith is on the path of righteousness. Are you wondering how she got there? Or more importantly, if can she stay on it? Set two years after an alternate season eight with minor tweaks in back-story.
