If there was anything aside from sex and Passions that Spike could get any pleasure out of, it was definitely this. Getting into the fight. Trading blows with an opponent, spilling blood. All of it. He remembered when he used to go out and kill people for fun. They usually weren't quite as defensive as Buffy was, but all the same it made him feel completely overjoyed. Help the helpless? No. Spike would much prefer to beat them down instead. It was different when he find a good match though. It made the fight all worthwhile. Killing Slayer's. Highly advanced vampire hungers. Whatever it was, Spike loved it. It gave him a rush that nothing else could possibly provide.
The corner of his mouth tilted upward as he charged her. This was fun.
