When we have a series of episodes where every single episode depends on and develops from the previous, we may call that a sequel, or maybe a continuum.
Now let us say that we have a collection of fables, episodes or anecdotes that have the same characters, the same milieu, and the same themes; yet, this time, the episodes are NOT interdependent. They don't depend on each other in that you can watch/read 'any' one of them be it (in terms of order) from a beginning, medial, or final season, without having to watch/read the previous to understand, appreciate, and enjoy it (the one you're watching/reading). What do we call the 'episode' in this case?
Examples: a sitcom comedy show, or a show like Dr Who. Or, in literature, the novels of Sherlock Holmes.
Is there a specific term to describe the 'independent episodes' of these works?
