A mysterious nun haunts the residents of the local nursing home. It soon turns out that an entire sisterhood serves under an old famous mythical beast...
Tropes
- Ancient Astronauts: The Gorgons of Greek myth.
- Big Damn Heroes: Maria shows up at the climax and uses Bea's mirror to block the transfer and send the snake entities back at the Gorgon.
- Bitch in Sheep's Clothing: The nuns are generally outright evil, but when Alan walks up to one of them, she switches to what the script calls “Julie Andrews mode”.
- Continuity Nod:
- Bea Nelson-Stanley, who was an Adventurer Archaeologist in her younger days, recalls having encountered the Sontarans among other alien races.
- Clyde jokes that he'll never grow old because someday, he'll be able to transplant his brain into a robot. Sarah Jane responds with an exasperated sigh, likely thinking about the Cybermen.
- Chrissie Jackson's taxi had an advert on it for Henrik's - the store Rose worked at in "Rose".
- Dramatic Irony: Alan reckons he would look good as a Greek statue.
- I Was Quite a Looker: Mrs Randall claims this.
- It Was Here, I Swear!: Chrissie returns to Sarah's house right after Alan is released from the petrification, none the wiser, protesting that Sarah has gotten carried away by making a statue of Alan, but now that he has changed back to normal, she cannot incriminate his neighbour for this, finally giving up.
- Light Is Not Good: Oh, so very much.
- Locking MacGyver in the Store Cupboard: Luke in the cellar full of gardening tools.
- Mythology Gag:
- There's only one person a Doctor Who fan will be thinking of when Luke says "I need a screwdriver."
- The Gorgon Medusa is defeated with a mirror. It's a Greek Mythology gag.
- Noodle Incident: Edgar had a run-in with the Sontarans at some point.
- Retired Badass: Judging by her moment of lucidity, Bea Nelson-Stanley must have been a force to be reckoned with in her younger years.
- Shout-Out:
- A nun threatens to show how her boss will "solve a problem like Maria."
- There is a mention of the 1964 movie The Gorgon starring Christopher Lee, Barbara Shelley, and Patrick Troughton. The mention of the latter also makes it a Mythology Gag.
- When she finds the 'statue of Alan', Chrissie refers to Sarah Jane as a 'bunny boiler'.
- When she realises Maria doesn't know the connection between mirrors and gorgons, she rolls her eyes and murmurs "what do they teach them in schools these days?"
- Stalker Shrine: Chrissie mistakes her petrified husband for one of these when she sees him standing in Sarah Jane's living room.
- Taken for Granite: Several Innocent Bystanders, one alien collaborator and Alan; though luckily for Alan, the process hadn't finished so he got better. Also the gorgon.
- The X of Y
- You Watch Too Much X: The nun's response when Clyde guesses she has tentacles under her habit. It turns out that the nuns are ordinary humans brainwashed into helping parasitic aliens.
