Excellent capture if the inner workings of newly souled Spike's fractured mind. His mental follow through to all those chances at killing Buffy nicely bookend his dreams of saving the slayer after her sacrifice. It is his love of her, his quest to grab her elusive, slippery heart, that has led him to this tortured place, so it's no wonder he dreams of ending her before the torture can begin.

This slips into canon beautifully, and you leave me feeling Spike's deep conflict and pain. Excellent job.
