Spike was on his way out of town to find Dru when he smelled it. Blood. A lot of blood. Curious, he pulled over and followed the scent. He found the witch’s boyfriend venting on whatever he could find.
The ground was slippery with blood and viscera and the wolf also wore a healthy coat of the stuff. Spike admired the sheer rage with which the boy fought and didn’t hesitate to stake a fledge sneaking up on him. Oz turned with a snarl and Spike smiled.
Fight or fuck? Oz attacked and Spike laughed.
Maybe a bit of both.
