[Spike had been right. It was incredibly satisfying to know he could go all out on the vampire and not have to worry about murdering someone. He didn't hold back and just as well, every blow he received only helped to keep his own fire going.
Of course, after a while he started to lose that energy and adrenalin. He started to get tired and achy. His limbs or body were taking enough of a beating to start to protest. He kept going as long as he could but soon the fatigue and alcohol combination was too much. One last blow to his gut and he toppled over backwards. There probably wasn't nearly enough force behind it to lay him out but Sam was sprawled over the ground. He groaned, breathing hard and letting the dome spin above him dizzily.]
