Chris Boal was a former Sunnydale High student who tried to seduce Darla, not knowing of her true status, ending up drained by the innocuous-looking vampire.
Behind the scenes
The character is named Chris Boal according to a deleted scene from the first draft of the unaired pilot script.
Chris was the show's first clever decoy into making the audience think he was a vampire due to his pale complexion, dark clothing and his attempt to seduce a seemingly innocent female figure. However, it turned out that he was merely a victim and Darla was the vampire in this instance.
His death is a twist on the opening of Night of the Living Dead, where the creepy brother, Johnny, is seen teasing Barbara, the horror film cliché blonde girl, about monsters in a way that she doesn't find funny and he eventually ends up eating her. In this case, the blonde eats the creepy guy.
