“Entropy,” by Drew Z. Greenberg
Ah, springtime on the Hellmouth. Vampires flee in apparent terror, all thoughts of drinking the blood of the living forgotten as... wait! There isn’t a Slayer in sight! No Buffy, no friends, no ex-lovers or off-and-on allies, not even a plucky victim, a much-missed Watcher or a misguided, doomed cop. Instead we see the Trio, on quads. They are completely ineffective in catching the vamps, who nearly get away. The Sunnydale vampire population is becoming weaker and more prone to bolting without cause as time goes on, I think.
And for good reason, perhaps, because now Buffy does show up, as does Spike. Warren, showing true nerve if not actual courage, edges closer until he’s fray-adjacent, all so he can snatch a mystic disk off the ground. The disk, naturally, was the reason the three of them were chasing the undead in the first place.
It was nice of the vamps to drop the thing before it got dusted along with their clothes.
