Recap: Doctor Who S18 E3 "Full Circle"
Login: A little patience goes a long way.
The Doctor: Yes. Too much patience goes absolutely nowhere.The TARDIS is on its way to Gallifrey to return Romana home, a task the Doctor has been putting off (and Romana has been letting him) for over a season, when it falls into a Negative Space Wedgie. The result is apparently only a momentary disturbance, but when they arrive at their destination, it isn't Gallifrey. They're in the right place, and the right time, but — they eventually discover — the wrong universe. (For ease of discussion, they subsequently dub the two universes "Normal Space" and "Exo-Space", or "N-Space" and "E-Space" for short.)Meanwhile, the inhabitants of the planet that isn't Gallifrey have problems of their own. Years ago, a starliner from the planet Terradon made a crash landing on the planet, where they were attacked by the local lifeforms. The survivors of the attack set about trying to repair the starliner and return to Terradon, a task at which their descendents are still working. And now the season of Mistfall is approaching, when all take shelter within the hull of the starliner to avoid the mysterious dangers lurking in the fog. But there are dangerous mysteries inside the starliner as well.At the end of the story, Adric, one of the people from the starliner, stows away in the TARDIS.
- Can't Argue With Time Lords: Romana is summoned back to Gallifrey. The Doctor's casual invokation of this trope almost reduces her to tears.
- Death by Origin Story
- Despair Event Horizon: Romana is clearly fighting not to cry at the thought of being forced back to Gallifrey with no say in the matter.
- Fog of Doom: Subverted; K9 reveals that it's non-toxic.
- Forgotten Fallen Friend: Adric only mentions his brother Varsh's death once after this story and seems to suffer no emotional repercussions from it, much to the chagrin of Matthew Waterhouse, who had lost his own older brother in real life.
- Friend to All Children: As usual, the Doctor.
- Healing Factor: It's a bit of a plot point in this story that all of Adric's people can heal faster than human normal. You'd think this would be handy for a companion, but it turns up once in Adric's stories and then never again.
- Infant Immortality: Sadly averted with the Marshchild.
- In Harm's Way: Romana really doesn't want to stay on Gallifrey again.
- Negative Space Wedgie: Here, a "Charged Vacuum Emboitment."
- People in Rubber Suits: The Marshmen
- Plug 'n' Play Technology: The image translator.
- Propaganda Machine: Some characters are convinced that Mistfall is this.
- Stock Episode Titles: 45 uses
- Tomato in the Mirror: The revelation that the Alzarians are really just evolved Marshmen, who replaced the original Terradon crash survivors after the survivors all died off or were killed.
- Ungrateful Bastard: When the young Tylos goes back against Varsh's warnings and saves one of the crew from a Marshman. The man pauses as he sees Tylos is being attacked, and promptly leaves him to die in his place.
- Up the Real Rabbit Hole: Of course our universe is the Normal one.
