I wanted to rec Kallysten's
seasonal_spuffy story
(Don't) Call Me Love.
It's a wonderful futurefic about Buffy's soul being born again and destined to stop an apocalypse. The question and expectation of whether this new Slayer will come to love Spike becomes more about whether these two can get past their own insecurities and hangups to discover what's real beneath both facades of external identity. What's true within one's soul. Kallysten dances a fine line between the old and new identity within Buffy and the newly called Cameron - but it's just enough to realize what's different for both doesn't matter compared to what's true underneath. It takes the concept of soulmates and makes it about souls who choose their mate for themselves, not souls who are destined to love because fate determines it for them.
