A brief recap of Doctor Who season 2 episode 3
Titled The Well, the show's third episode takes the Doctor and Belinda 500,000 years into the future on a mysterious planet named 6767. They arrive at a mining colony to find soldiers investigating a scene of massacre with a ton of dead bodies. The mission commander, Shaya Costallion, informs the duo that their ship will take another five hours to return as the planet is engulfed in galvanic radiation.
The soldiers discover the only survivor of the massacre, a deaf woman named Aliss Fenley, who claims the others started acting erratically before killing each other. The Doctor recollects his past visit to the planet, when it was called Midnight, and remembers the terrifying entity that sent shivers down his spine.
To his horror, he notices the entity's presence as a shadow behind Aliss, killing whoever stands behind her. As the entity begins killing the soldiers one after the other, the Doctor creates a mirror effect from the reflective mercury to trick it into killing itself. However, it latches onto Belinda before the group can escape inside an airlock.
Shaya shoots Belinda (which she survives), causing the entity to attach itself to the former. Shaya sacrifices herself to save the group by jumping into the titular well that the entity came from. However, the last minutes of the episode hint that the entity has survived and attached itself to one of the surviving soldiers, Mo.
As they escape in TARDIS, the Doctor and Belinda reflect on the fact that the group had never heard of Earth, implying that something catastrophic must have happened to the planet in the past half a million years.
