While on the phone with Willow, Cordelia tells her that Wesley is there and then tells him that "Willow says hey."

Special Effects Supervisor Loni Peristere says they couldn't afford to shoot Vanessa's perspective using green-screen, so instead they came up with the "crazy idea" of painting the actors with glow-in-the-dark paint and shooting the scenes in the dark. The effect was intensified by offsetting the footage to create tracers, and then reversing the image - "it was supposed to tell the story that she sees the action before it actually happens," explains Peristere. "It was such a wacky idea and it really worked out well."
