Black Buddha: Part 1

A shot outside the Raven with two extras, a bald smoker and a long-haired person opening the door to club and going in, was recycled from Season 2, Episode 4, Bad Blood. That same scene was also used as opening shot for Season 2, Episode 22, Curiouser and Curiouser.

When Tracy finds Vachon at the morgue, his right hand is missing. When she regains consciousness in her car with him driving with both his hands, she simply says "your hand" and doesn't question it further.
