This situation DOES NOT EXIST on Wikipedia. One doesn't go to our
article on a fictional topic expecting light banter about the
characters or a discussion of their relative hotness. One expects the

of the article to be in the business of spoilers; they don't discuss how
hot the characters are, but they do discuss other things which are not
spoilers.
One "expects the whole deal" only on a per-article basis, not on a per-section
but spoilers can be put on individual sections, or even within a section if
the spoiler doesn't appear at its top.
