Companion: Donna Noble (Catherine Tate)
Summary: The Doctor and Donna visit the planet Midnight. The Doctor plans to take a shuttle to see a sapphire waterfall, but Donna is uninterested. The Doctor boards the shuttle, saying “What could possibly go wrong?” and effectively jinxing the trip. The shuttle soon malfunctions, and all the passengers are trapped. Knocking is heard outside, and suddenly one of the passengers starts copying everyone’s words uncontrollably. She is now possessed , and as the monster becomes stronger, the Doctor begins to lose control over the situation. And the other passengers slowly distrust the Doctor.
Review: Oh crap, this episode! I LOVE it! Bottle episodes have always been Doctor Who’s greatest strength, and this is one of the best. What makes the episode so great is how minimal it is. We never see the monster at all, and that’s what makes it all the more frightening. The Doctor is usually the one who is in control, but this time he’s not. And with no companion to help, the Doctor is completely on his own.
Continuity: We see yet another image of Rose for this season, as it is a motif for the 4th Series. The Doctor learns of the lost moon of Poosh in this episode, which is later referenced in “The Stolen Earth/Journey’s End”.
Trivia: This episode marks another guest appearance by Patrick Troughton’s son David Troughton. He also appeared in “The Curse of Peladon” and “The Monster of Peladon”, where he played Peladon and he also portrayed the Black Guardian, a foe of the Fourth and Fifth Doctors.
