Clara Oswald

Clara Oswald was a human living on Earth at some point after the 19th century.

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 and Oswin Oswald.

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 wanted to travel after university, but before she left she spent a week with family friends. During that week, their mother died, and she put off her travels to nanny for the children, Artie and Angie. Although she didn't have computer skills, she was very clever and enjoyed an old book called Summer Falls, where she preferred the eleventh chapter to the tenth. Despite her inadequacy with the Internet, she attempted to use it one morning at Angie's house and created a mnemonic device, "Run you clever boy and remember," to help her recall the wifi password, but had to contact tech support anyway. "A woman in the shop" gave her the number to the Doctor's TARDIS and although he tried to help her, she clicked on the Great Intelligence's wifi connection by accident. The Doctor arrived in time to stop Clara from being completely downloaded, but she accidentally came back with the tech package that Miss Kizlet gave her. This allowed her to hack the Great Intelligence's operatives and discover their location before she was downloaded again, this time successfully. After being freed the Internet a second time, Clara confronted the Doctor about what happened to her and they discussed why her desire to travel and her nanny 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.
