Clara Oswald splinters

Several splinters from Clara Oswald were created when she stepped into the Doctor's timeline.

These splinters met the Doctor in many forms (every form was a person with time sensitivity), each time being born and dying. She met and saved the lives of the Doctor's first twelve incarnations (excluding his war incarnation). She noted, however, that he rarely ever noticed her. (TV: The Name of the Doctor) Though Clara initially believed that all of her splinters had died after saving the Doctor, she later learnt that many had survived encountering him and lived their own lives. (COMIC: Blood and Ice) Clara retained jumbled memories of her echoes, remembering some moments of their lives in great detail while recalling others only as vague dreams. (PROSE: Into the Nowhere, GAME: Lost in Time) Although River Song initially told Clara that the echoes "wouldn't be her", (TV: The Name of the Doctor) the prime Clara sometimes referred to elements of her splinters' lives as things which had occurred to her personally. (GAME: Lost in Time)

Her many lives and encounters with the Doctor included, but were certainly not limited to:
 * The First Doctor as he was stealing a TARDIS from Gallifrey. She told him not to steal the one he intended to take but the one next to it, as even though the navigation system was "knackered", he would have much more fun.
 * The Second and Eighth Doctors were both present in a park with palm trees.
 * The Third Doctor driving past her in Bessie. When she tried to shout his name, he turned to his rear view mirror, catching a glimpse of her.
 * The Fourth Doctor on Gallifrey where Clara tried to catch up to him.
 * The Fifth Doctor battling Omega inside the Matrix.
 * The Sixth Doctor walking through the TARDIS and past one of Clara's splinters; she called out to him, but he didn't seem to notice her.
 * She watched the Tenth Doctor while in the Library. (TV: The Name of the Doctor)
 * Clara spotted the Seventh Doctor clinging onto the edge of a cliff on Iceworld in the far future (TV: Dragonfire) and he seemed to notice her. (TV: The Name of the Doctor)
 * As a queen or monarch of some sort.
 * As a Morestran.
 * As an inhabitant of Atlantis.
 * As a member of the Happiness Patrol.
 * As a Guardian on the Ark during the 57th Segment of Time.
 * As a Maori from New Zealand.
 * As an Egyptian, possibly a monarch Nefertiti.
 * As a military officer, circa World War II.
 * As a 51st century astronaut. (COMIC: Blood and Ice)

At one point after Amy Pond and Rory Williams were sent to the past in New York City, an elderly echo of Clara noticed that Amy had a similar "glow" about her that the Doctor had, but Amy's was fading. She decided to follow Amy, in case she ever needed help. One Fall, when Amy and Rory vacationed at Lake Erie, Amy finally spoke to her and the echo asked her to pass on a message: "Run you clever boy, and remember..." Amy later wrote about this encounter in a foreword to an edition of her book Summer Falls, addressing it to the Doctor; her description of the encounter and her quoting of Clara leaves it unclear as to whether this echo ever actually encountered the Doctor.

In November of 1963, Constable Oswald had filled out the missing person report for Susan Foreman. (PROSE: Susan's Diary)

Behind the scenes
Ashlyn Oswin, a recurring character from the independent series 10,000 Dawns, was suggested to be a splinter of Clara Oswald, with both the design of the character being based off the likeness of Jenna Coleman and the April Fools' Day special The Forgotten Heroines of 10,000 Dawns implying she was a lost splinter, as well as implying that she was the individual posing as Clara whom the Twelfth Doctor briefly interacted with in Twice Upon a Time, rather than actually Clara herself as was the official intent. As the story featured no license to any DWU elements, it isn't covered by this Wiki, although the crossover story Birthdays are Made for Memories that featured a cameo of Ashlyn, is covered.
