Clara Oswald

Clara Oswald was a companion of the Eleventh Doctor.

She appeared to be a version of the woman whom the Eleventh Doctor believed to be one and the same, along with Clara Oswin Oswald, Oswin Oswald and Clara Oswald.

She was a fan of the book Summer Falls, written by Amelia Williams, of which Chapter 11 was her favourite. (TV: The Bells of Saint John)

Biography
At some point in her life, she and her friend visited a graveyard, where she walked by the tombstone of 19th century Clara Oswald and ironically stated, "I don't believe in ghosts." (TV: The Snowmen)

Clara originally planned to travel after attending university, spending the week before leaving with family friends. During this week, however, their mother died, and she decided to stay in order to be a nanny for the children, Artie and Angie Maitland. Despite this she still intended to travel at some point, and kept the book which was her inspiration, 101 Places to See.

She owned a laptop but, as she did not have any computer skills, phoned a technical support line given to her by "a woman in the shop" who described it as the best "in the universe", which was in fact the number to the phone on the front of the Doctor's TARDIS. She created a mnemonic device, "Run you clever boy and remember," to help her recall her Wi-Fi password, but later clicked on the Great Intelligence's Wi-Fi connection when the Eleventh Doctor caused her to mistype it.

After accessing the Intelligence's Wi-Fi, Miss Kizlet sent a Spoonhead to upload her to the data cloud, which disguised itself as the little girl on the cover of Summer Falls. She was also given computer knowledge and technical skills. Although the Doctor arrived in time to stop Clara from being completely uploaded, she retained the technical knowledge that Miss Kizlet had given her.

The Doctor first took her aboard the TARDIS in order to stop a commercial aeroplane that had been sent to kill them, and then to have breakfast the next morning, arriving at the South Bank, whilst Kizlet had to take "the long way round".

After the Doctor was able to hack into the Intelligence's basic systems, Clara was able to use her new technical skills in order to access his employees webcams and use them to find their social networking profiles which gave their location, the Shard. As soon as she had figured this out, she was uploaded to the data cloud by a Spoonhead disguised as the Doctor.

After being downloaded back to her body a second time, Clara confronted the Doctor about what happened to her and they discussed her desire to travel, as well as her responsibilities. The Doctor asked her to travel with him, promising to bring her back without anyone ever knowing she was gone, but she surprised him by refusing to go and telling him to come back the following day, after seven, and ask again.
