Trivia / The Sarah Jane Adventures S4 E5-6 "Death of the Doctor"

• The Character Died with Him: Sarah mentions Harry Sullivan in the past tense, implying that he passed away at some point (Ian Marter having died in 1986).
• Character Outlives Actor: Barbara Wright and Ben Jackson are both mentioned to still be alive, despite Jacqueline Hill and Michael Craze's deaths.
• Fandom Nod
  Clyde: Even your eyes are different! For some reason I thought the eyes would stay the same. Can you change colour or are you always white?
  The Doctor: Not at all! I can be anything!
  Clyde: And is there a limit? I mean, how many times can you change?
  The Doctor: Five hundred and seven.
  Clyde: Oh!

  • Fridge Brilliance sets in when you realize what Russell T Davies did there: Five hundred and seven. 507. 5 + 0 + 7 = 12, referring to the Doctor's original 12 regenerations.
  • When Clyde, Rani and Santiago find their way to the Groske's home in the ventilation ducts, there is a stuffed panda toy◊ in the background. This is possibly a nod to Katy Manning's Doctor Who Expanded Universe role as Iris Wildthyme and her stuffed companion Panda.
• Role Reprise: Katy Manning returns on-screen as Jo Jones for the first time since "The Green Death" 37 years prior.
• What Could Have Been: Steven Moffat suggested that Amy Pond make a cameo, but the budget didn't stretch to Karen Gillan.
