 According to Aycox, the exorcism of the demon from Meg Masters took two days to shoot; the first day of filming lasted 13 hours, while the second lasted for "about a half a day". Director Kim Manners used 360-degree shots and close-ups to make the sequence exciting. In the scene following the exorcism, in which Bobby is bent over a dying Meg, Aycox and Ackles read their lines off-screen so that Beaver's reaction could be shot. However, the two were "so slap-happy" to be almost done that they could not stop laughing; to everyone's surprise, Beaver was able to keep a straight face. The set — Bobby Singer's home — was filled with waist-high stacks of six thousand books.
