Running from the Inevitable by The Enemy of Reality
With a tub of ice-cream in her lap, Buffy wallows in misery over Angel disappearing out of her life in a puff of overly dramatic smoke. Her life gets turned upside down when her hated enemy staggers drunk off his face to her front porch. Not only is he demanding her help, he is invading her personal space. She's had enough!
Post-S3. Angel and Drusilla are a no show. Meanwhile Buffy and Spike embark on an adventure full of childish bickering, UST and reluctant camaraderie that will change what they thought were unshakable perceptions. |
