I just want to say that even though Sarah didn't particularly love this pairing, it was my favorite. Angel was cursed with a soul. Their love was tragic, but it could never be. But Spike fell for Buffy of his own accord and did everything to be with her. He was there for her when no one could understand what she was dealing with. He was there for Dawn through EVERYTHING. He chose to go through the agony and hardships of getting a soul so he could love Buffy legitimately (in her eyes).
