>Bob made his first appearance in the pilot episode, "Northwest Passage", where he makes a brief appearance in a vision seen by Sarah Palmer. The character eventually grew into the series' main antagonist in the second season. Silva, a set dresser on the pilot, was given the role of Bob after a reflection of his face in a mirror was accidentally captured by the camera during filming. When series creator David Lynch saw Silva's face, he liked it so much he kept it in the show, and cast him as Bob.[2]
