Listen (TV story)

 was the fourth episode of the eighth series of Doctor Who produced by BBC Wales. This episode is notable for providing a rare glimpse of the Doctor's childhood, as the First Doctor is seen as a child in this story. Also it shows Clara having affected the Doctor's timeline on a more personal level, as her soothing words to the frightened younger Doctor gave the War Doctor the idea many years later during the Last Great Time War to use the barn as the place to activate The Moment.

Synopsis
The Doctor has been pondering something for quite a long time: are we ever truly alone? With Clara at his side, they soon find the answer more terrifying and more complicated then they had ever imagined.

In his determination for an answer, the Time Lord will find himself delving into familiar pasts and eerie futures. Does the answer to the question lie at the end of the Universe? It's time to learn what scares this old man the most.

The Doctor

 * The Gallifreyan adult who visited the young Doctor in the barn was skeptical of him joining the Academy and becoming a Time Lord.
 * Clara has affected the Doctor's timeline since his childhood.
 * The Twelfth Doctor, upon awaking in the TARDIS, mentions 'Sontarans perverting the course of human history' to Orson Pink, presumably waking from a dream, repeating his first words as the Fourth Doctor. (TV: Robot)
 * The "shortest horror story" has been described as "The last man on Earth sat alone in a room. There was a knock on the door...". It is the opening (and closing) line of the story "Knock", written by Fredric Brown.
 * The Doctor in his youth didn't want his brother and the other boys at the House of Lungbarrow to hear him cry, so he sleeps in a barn.

Laws of Time

 * Clara breaks the Third Law of time and travels back in time on Gallifrey. How the time lock is bypassed isn't explained.
 * Clara breaks the First Law of time by crossing her own timeline.

Individuals

 * Clara says she'd never been to Gloucester.

Story notes

 * Clara's encounter with the Doctor as a young boy marks the second time a version of her has met his original incarnation, and the first from his perspective. One of her splinters created after she entered the Doctor's time stream had met the older First Doctor, suggesting which TARDIS to steal as he escaped Gallifrey. (TV: The Name of the Doctor)
 * Aside from archive footage and body/voice doubles this episode marks the first time in years that the First Doctor had appeared in an episode of the show, as well as been played by a different actor.
