Trivia / Arrow S 4 E 6 Lost Souls

• Development Gag: The team has to steal a component of the machine to return Ray to normal from Ted Kord's company, in reference to how Ray was originally going to be Kord until the DC higher-ups wouldn't let the show use him.
• Real Life Writes the Plot: Dinah didn't appear when she was speaking with Sara because actress Alex Kingston was busy filming Doctor Who in the UK.
