This is the first episode that we really get to see Spike's feelings for Buffy. And they start the way they will continue for the rest of the series, for the most part--his love for her is steeped in both tenderness and violence, never a good combination. Passion, for Spike, is tied to physical fighting and pain. The episode follows the inner conflict in Spike that is flitting around under the surface--he can't decide whether he wants to kill her or screw her. This is somewhat resolved in the end of the episode when Spike goes to find Buffy, toting a shotgun and promising to kill her, but finds her sitting on her front porch crying because her mother is sick. Instead of shooting her on the spot he sits down beside her to comfort her. A lot of people would see this as the end of his internal conflict, but it isn't--their relationship is violence and passion for the rest of the series, in a typically unhealthy way.
