The Girl Who Died (TV story)

 was the fifth episode of the ninth series of Doctor Who produced by BBC Wales.

The story is notable because it reveals the reason as to why the Twelfth Doctor regenerated with the same appearance as Lobus Caecilius: to remind himself to, no matter how impossible it seemed, always save someone, as he had saved Caecilius in his tenth incarnation. This marks the first time in the narrative of Doctor Who that an explanation has been given for why the Doctor looked similar to an individual he had met before, as Colin Baker, who had played the Time Lord Maxil, would later play the sixth incarnation of the Doctor. But unlike the Twelfth Doctor it was never explained how or why the Sixth Doctor took on an appearance similar to Maxil's.

It also revisited the idea of something alien taking over a historic era by impersonating an important figure. The concept was last seen in Robot of Sherwood.

It further re-introduced the concept of immortality, which was last seen in Journey's End with Jack Harkness, a former companion to the Doctor.

Synopsis
The Doctor and Clara are forced to help protect a Viking village from the Mire, one of the deadliest warrior races in the galaxy. Are they fated to suffer death due to being outnumbered? So what is it about a simple Viking girl that interests the Time Lord?

Plot
Clara is floating in space, calling the TARDIS for a pickup. However, the Doctor is busy trying to resolve a conflict, and is having trouble locking on to her location. Clara then notices that something is in her spacesuit; the Doctor suggests its a brain-eating parasite with an odd name - Love Sprite. Within moments of it getting too close to Clara's head, the Doctor materializes the TARDIS around him and takes off her helmet. As Clara re-ajusts, the Doctor squashes the creature; he explains that he sent the hostiles far away from their battlefield.

The Doctor decides to land the TARDIS to check on any damage. However, the moment they land, they are surrounded by vikings. The Doctor pulls out his sonic sunglasses, gloating that he wears the highest technology that the primatives will ever see on his face. A viking takes the glasses and snaps them in two. Seeing that he should have had a backup plan, the Doctor flatly tells Clara that they're going with the vikings.
