Tamsen McDonough, who voices Lucy, the ship's computer, is never actually seen until Killjoys: I Love Lucy (2016). In that episode, she plays a cyborg who has had Lucy's artificial consciousness downloaded into it.

Thom Allison, who plays Pree, has a beautiful voice! He sings The Wayfaring Stranger (on S3:E9 The Reckoning Ball) at the Royale. Unfortunately, the spiritual/folk song becomes eerie as it is punctuated dramatically with brief scenes where: Turin toasts a drink with Gared, Dav and John talk and decide to go along with Dutch's plan, and Aneela (disguised as Dutch) murders Alvis. Allison has a holiday album available. The Wayfaring Stranger is an MP3.
