In the near future, the Moon is revealed to be a giant egg about to hatch. A creature inside is causing destructive gravitational effects on Earth. Clara, the Doctor, and Courtney must decide whether to kill the creature or let it live. The Doctor forces Clara to make the choice herself. She chooses to save it, and the creature hatches harmlessly, laying a new egg. Clara is angered by the DoctorΓÇÖs manipulation and questions their relationship.
The Doctor takes Clara Oswald and Courtney Woods to what he claims is the Moon in the past, but they instead arrive in the near future where the Moon is revealed to be a giant egg on the verge of hatching.
The Doctor believes humanity should decide its own future, so he forces Clara to choose whether to destroy the creature inside the Moon or let it hatch, risking EarthΓÇÖs safety.
The Moon is revealed to be an enormous alien creature about to hatch. When it does, it lays another egg, restoring the Moon and avoiding long term consequences.
Clara becomes angry at the Doctor for abandoning her during a critical moment, causing a major rift between them and challenging their trust.
The episode deals with choice, responsibility, and the burden of decision making. It also explores trust and the consequences of leadership.
