Behind the scenes

  • In real life, Doctor Who, commonly referred to as The Doctor, is indeed a staple pop culture character from the eponymous British TV series.
    • Joanie's mention is correct: considering she was born in 1998, Cecile became pregnant with her sibling seven Doctors later, as from 1996 there were technically seven incarnations of the character, including one inserted retroactively right after Eighth Doctor, who was concurrent with Joanie's birth first appearing in 1996.
    • The Doctor is indeed often seen using a sonic instrument, albeit usually not a wrench, but a screwdriver. However, sonic wrench was once mentioned in an audio play spin-off, which is canon to main TV continuity. It is unknown whether mention just spoofed the sonic screwdriver and resulted into something already invented or writers Thomas Pound and Jeff Hersh specifically referenced the audio play.
