A Gnarol demon attended Xander and Anya's wedding
Behind the Scenes
In the original script of "As You Were", Anya and Xander argue over where one of their wedding guests, a Gnarol, would be seated. Xander suggests putting him on table five which is for singles while Anya insists they place on table two with Xander's aunt and uncle where it's more prominent, warning Xander that the Gnarol would kill them for insulting him.
