In the middle of the perfectly symmetrical blue dunes of Indigo 3, there's a temple devoted to chaos. The nuns are a bit upset, though, when people suddenly get bitten in half by sentient crocodiles.
Lucie is forced to become a nun, is subsequently kidnapped and hypnotised by the crocodiles, and she and the Eighth Doctor are told to go bash in each other's skulls in mortal combat.
The Doctor: "Am I alright? Lucie's possessed by an aging crocodile, armed with an evil mace, smashing her way out of a hypothetical cupboard in a vision of the ancient world of Sobek, in order to kill me, but otherwise..."
After all that, Lucie is almost forced to stay at the temple forever, but the nuns decide that the Doctor is a chaotic element that should be tempered by Lucie's calm presence. They charge her with being his moral guardian on his future journeys. The Doctor and Lucie try very hard to keep a straight face.

- Brainwashed and Crazy: Lucie when she is possessed and tries to kill the Doctor.

- They Should Have Sent A Poet: Indigo 3 is a planet of perfectly symmetrical blue dunes, where once in every 83 years, the blue rains cover the sand with gorgeous flowers.
- Why Did It Have to Be Snakes?: Lucie's terrified of crocodiles.
- You Put the "X" in "XY": She puts the 'Lucie' in 'hallucination'.
