Note: If a series focuses on a particular Doctor, there is no need to add the relevant category to each individual episode. It is perfectly acceptable to add the category to the series page as a whole and leave out individual episodes.

For example, Twelfth Doctor Adventures is in the category "Stories featuring the Twelfth Doctor", but not all of its episodes are in the category. This helps to keep the categories from clogging up.
