- Actor-Shared Background: Number Six confirms the Village's information that he was born on 19th March 1928 and volunteers that it was at 3:15 am. This was Patrick McGoohan's real birth information.
- Technology Marches On: The episode uses a cordless phone as an eerie, impossible-seeming device that Number Six does a Double Take at. Though it does still have an odd Zeerust design so nowadays it can seem like that's what he's noticing.
