As we gear up for the Doctor Who two-part season finale, the stakes have finally been revealed - and it's not looking good for Planet Earth.
In the latest episode, The Interstellar Song Contest, which is set 900 years in the future, the hologram of Graham is summoned to the museum area of the Harmony Arena when Belinda (Varada Sethu) mentions her home - Planet Earth.
Reeling off facts about the planet, Graham says: "Planet Earth: age-old home of the human race. Also dogs, cats, polar bears and measles."
When the Doctor orders him to explain, Graham goes on: "The history books say Planet Earth ended on the old Earth date May 24th 2025" - the date Belinda left Earth.
Graham continues: "It is said the planet disintegrated into rock and dust and ashes. All the memories here were sieved from the rubble of a civilisation that died in a single second. Cause: unknown."
As for what could have caused the destruction of Earth, there are plenty of possibilities. But our guess is it's something to do with Mrs Flood (Anita Dobson), who seems hell-bent on causing havoc in the Doctor's world.
Doctor Who continues next Saturday (24th May), with new episodes available from 8am on Saturdays on BBC iPlayer in the UK and later the same day on BBC One. The series is available on Disney+ outside of the UK.
