Betrayed, Forgotten, Abandoned. by Loup Noir
Summary: In the aftermath of her battle with Angelus, an injured and emotionally shattered Buffy comes to the realisation that she has nothing left: her mother has disowned her, her friends have abandoned her and Angel, soul newly restored, has left her alone as he flees for the scene of his crime. Spike's unlife is left bereft of purpose now that Drusilla is gone, thrown into Hell by his hated grandsire. The two broken souls realise that all they have are each other and desperately cling to the last, fragile connection as they take their leave from Sunnydale.
Perhaps the two mortal enemies can rebuild that which they have lost...
