The only mystery worth solving.
She's not possible.
CLARA OSWIN OSWALD ✖ SERIES: DOCTOR WHO ✖ FC: JENNA LOUISE-COLEMAN ✖ RESERVED
Clara Oswald is a mystery. The most important mystery the Doctor has said is worth solving. The Doctor has encountered the woman thrice now, once in Victorian England where she worked as a barmaid and also a governess. The Doctor first met Clara under the name of Oswin Oswald, as a human-converted dalek, whom was a junior entertainment manager aboard the Alaska starliner, which had crashed into the dalek asylum before conversion. Because of what had happened to the woman was so horrific, Oswin created her own dream surroundings around her where she believed she now lived and survived off of soufflés. Second time round in was in 19th Century London where Clara was extremely curious of the Doctor and followed him to the TARDIS on a cloud, joining him again as a plan to trap the ice governess. Whilst inside the TARDIS, Clara asked whether there was a kitchen, due to her liking to make soufflés. The Doctor gave her a key just before the governess reached the top and dragged Clara down to her death. The soufflés were what made the Doctor realize that Clara and Oswin were indeed the same woman. The Doctor searched for Clara until he found her again in modern day Britain, where she is now his current companion and assistant during their adventures through time and space. Clara herself is a feisty young woman who possesses very high intelligence and can’t help her curiosity at times. She has a feisty, fearless yet flirtatious attitude and can easily don a new personality and accent if needed.
That’s difficult to answer. The doctor can take us pretty much anywhere, so really I’d love to see the stars and visit far off places. This planet is cutting it a bit slim, don’t you think?

Surprise, sometimes, will come around.
I will surprise you sometime.
I’ll come around.
