WHITE HAT. Buffyverse Term/Concept/Idea/Intratext.

Designation used by Vamp Xander in "The Wish" to name those individuals (Oz, Larry, Giles) who continue to fight the good fight against the vampire takeover of a Buffy-less Sunnydale. The name obviously derives from the classic Western, in which the good guy routinely, conventionally wore a white hat.
