 The cast and crew were very emotional during filming, as they were concerned that this might be the last episode ever filmed and the series cancelled if the strike was a lengthy one. Olmos helped to work up the cast's emotions for the shoot by telling everyone that the show was ending. According to co-writer Weddle, Olmos repeatedly told the cast, "This is the end, I think we all feel that. They're not going to bring the show back. They 'll pull the sets down. We'll never shoot another episode." Actress Kandyse McClure improvised the lullaby her character hums before committing suicide, and series composer Bear McCreary used the melody for part of the episode's musical soundtrack.
