6. Why Does Clara Skip The Number 23?
Doctor Who premiered on November 23, 1963. When the Doctor flips through the book 101 Places to See he finds on Claras shelf he comes across a page that is titled Property of with a chart of Claras years up to the age of 24. Year 23, however, is missing. When Clara types the password for the wifi (RYCBAR123) she is stopped by the Doctor before she can type the 3 instead mistyping it as 4. Its almost as if Clara cannot access the concept of 23 like a hard drive that cannot access a certain sector and skips over it. Clara's tombstone in "The Snowmen" lists her birthday as November 23, the same day as the birth of Doctor Who. What is the significance of 23 for both the Doctor and Clara?
