Biography
Travels with the Eleventh Doctor
She was a companion of the Doctor in the incarnation prior to the Twelfth Doctor, (COMIC: The Daft Dimension 477) much as her N-Space counterpart first travelled with the Eleventh Doctor. Also like her, (TV: The Bells of Saint John, The Name of the Doctor) she once entered the Doctor's time stream. She was subsequently able to remember what she had learned via the experience. (COMIC: The Daft Dimension 485)
Travels with the Twelfth Doctor
Shortly after a newly-regenerated Twelfth Doctor decided to overhaul the look of his TARDIS's control room to be extremely minimalistic, she gently tried to get him to understand that his idea was far too simplified. (COMIC: The Daft Dimension 477) He would eventually relent. (COMIC: The Daft Dimension 478, The Daft Dimension 479)
When she saw how large his Two Thousand Year Diary had gotten, Clara tried to convince the Doctor to go digital, but he refused, even as lugging the huge book around threatened to injure his back. (COMIC: The Daft Dimension 478)
After an adventure where she and the Doctor had met a legendary character, Clara asked the Doctor why they couldn't meet any more such figures, but the Doctor insisted that the vast majority were fictional. He was particularly dismissive of the possibility of meeting a certain being with "ludicrous" long arms, only for him to appear from behind the Doctor just as he and Clara walked out of the TARDIS onto a grassy plain. (COMIC: The Daft Dimension 479)
After going through an adventure similar to the N-Space Clara and Doctor's adventure on the Moon, (TV: Kill the Moon, COMIC: The Daft Dimension 480) Clara questioned how the creature had laid an egg bigger than itself, prompting the Doctor to demonstrate that the new moon was in fact very tiny, but in much closer orbit to the Earth than its predecessor. (COMIC: The Daft Dimension 480)
The Doctor and Clara later had a Christmas party in the TARDIS with Rusty. Despite the Dalek's objections, the two humanoids insisted on wrapping him in Christmas decorations and thus using him as a Christmas tree. As he protested, Rusty called the Doctor a "good Dalek" and insisted that he could see "beauty, divinity [and] hatred" in the Doctor's soul, but he failed to disturb the Doctor. (COMIC: The Daft Dimension 481)
Some time later, with the Doctor now having switched the control room desktop theme again to light-blue hexagons with an intensely blue time column, Clara finally asked the Doctor what the "significance" of the blackboard he'd installed in the control room really was. The Doctor gleefully demonstrated that the sound of scraping against the board was unbearable to many of his enemies, making a Cyberman, Dalek, Silent and Zarbi who'd snuck aboard all cringe and beg for mercy. (COMIC: The Daft Dimension 482)
Noticing, thanks to her knowledge of the Doctor's time stream, that it was the tenth anniversary "by Earth standards" of the Doctor's return from the Time War, Clara decided to surprise the Doctor with a cake. However, when she showed him th ten candles she had bought, he reminded her that by his own subjective timeline, counting all the time spent on Trenzalore, it was more like a thousand years. Annoyed, Clara gave up on the cake-and-candles idea, resolving to bake a soufflé instead. (COMIC: The Daft Dimension 485)
Clara was later unimpressed when she found the Doctor obsessively engaged in a flame war with Davros, with both men treated as equivalent to a "phase two" of the Time War even though it was purely text-based and involved such salvos as the Doctor making fun of Davros for misspelling the word "loser" as "looser".
