Crossword clue: Series finale?

The answer "ETC" is short for "et cetera," which means "and other things" or "and so on." In a series finale, many storylines and characters come to an end, but there are often hints about what happens next or other details left unsaid. So, "ETC" fits well because it suggests that there is more to the story beyond just the finale. It's a clever way to indicate that the series is ending, but not everything is fully wrapped up.
